Abstract: Cybersecurity is a critical aspect for automotive applications. In this paper we approach this issue from a cryptographic point of view. In particular, we propose the use of a post-quantum code based cryptosystem based on a special family of low-density parity-check (LDPC) codes, called fully connected monomial LDPC codes. We also investigate some properties of these codes.

Abstract: Information security has become a crucial issue not only from the technical standpoint, but also from the managerial standpoint. The necessity for organizations to understand and manage cyber risk has led to the rise of a plethora of risk assessment methods and tools. These approaches are often difficult to interpret and complex to manage for organizations. In this paper, we propose a simple and quantitative method for the estimation of the likelihood of occurrence of a cyber incident. Our approach uses a generalized logistic function and a cumulative geometric distribution to combine the maturity and the complexity of the technical infrastructure of an organization with its attractiveness towards cyber criminals.

Data transmission in automotive applications and security/safety requirements
Proceedings 2020 AEIT AUTOMOTIVE
Autore/i: Cancellieri, Giovanni; Battaglioni, Massimo
Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: Radio communications have a fundamental importance for assuring data exchange between vehicles and from infrastructures to vehicles, or vice-versa. With reference to assisted driving and even completely autonomous driving, such communications must satisfy very high degree of security, with the goal of assuring also the safety of drivers and passengers. Two frameworks are expected to provide a support for secure data transmissions: 5G technology and wireless V2X protocols. Interoperability between them and a proper interface with automotive buses are recommended, in order to reach the best performance and to decrease the costs. In this respect, an efficient use of channel coding can guarantee error correction, i.e., reliable communication, and also strong resilience against cyber attacks.

Abstract: The human society in the information age deeply relies on digital information processing, communication and storage. Photonic routing and switchingis expected to be exploited in future all-optical networks. Channel coding is needed in order to protect information against natural disturbances, and modern coding schemes are able to reach the ultimate limits predicted by Shannon. On the other hand, postquantum cryptography is necessary for assuring security against cyber attackers, possibly provided with quantum computers. Source coding, especially in video data compression, is recommended for optimizing the bandwidth usage. Spread spectrum systems can solve the problem of radio transmissions over common frequency bands. These technologies are of crucial importance for the evolution of networks and of the whole Internet, allowing people to interact each other and access information in the web. Nowadays, the conventional Internet of people has moved into the pervasive Internet of Things providing innovative services in a variety of application fields. In this respect, domotic systems, based on ambient and wearable sensors, appear of dramatic importance in the design of future assisted living protocols.

Autore/i: Battaglioni, Massimo; Santini, Paolo; Baldi, Marco; Cancellieri, Giovanni
Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: In this paper we propose an efficient and general method to obtain structured generator matrices for QC-LDPC codes. Moreover, we devote particular attention to the family of fully-connected monomial codes and perform a statistical analysis of their low-weight unavoidable codewords, whose weight gives an upper bound on their minimum distance.

Connections between low-weight codewords and cycles in spatially coupled LDPC convolutional codes
IEEE TRANSACTIONS ON COMMUNICATIONS
Autore/i: Battaglioni, Massimo; Baldi, Marco; Cancellieri, Giovanni
Classificazione: 1 Contributo su Rivista
Abstract: In this paper time-invariant spatially coupled low-density parity-check convolutional codes (SC-LDPC-CCs) are considered, and the connections existing between their low-weight codewords and cycles in their Tanner graphs are studied. Using the polynomial representation of these codes, we show that parity-check matrices having columns with weight ≥ 2 can be analyzed considering a certain number of parity-check sub-matrices having regular columns with weight 2. These sub-matrices are associated to cycles in the code Tanner graph and define as many codes we denote as component codes. Based on this observation, we find that codewords of the main code can be expressed as a combination of codewords of the component codes. The design of codes free of codewords up to a certain weight is also addressed. We show that low-weight codewords in the main code can be avoided by removing some types of cycles in its Tanner graph. Our design approach is applied to some well known ensembles of SC-LDPC-CCs to prove its effectiveness.

Design and Analysis of Time-Invariant SC-LDPC Convolutional Codes with Small Constraint Length
IEEE TRANSACTIONS ON COMMUNICATIONS
Autore/i: Battaglioni, Massimo; Tasdighi, Alireza; Cancellieri, Giovanni; Chiaraluce, Franco; Baldi, Marco
Classificazione: 1 Contributo su Rivista
Abstract: In this paper, we deal with time-invariant spatially coupled low-density parity-check convolutional codes (SC-LDPCCCs). Classic design approaches usually start from quasi-cyclic low-density parity-check (QC-LDPC) block codes and exploit suitable unwrapping procedures to obtain SC-LDPC-CCs. We show that the direct design of the SC-LDPC-CCs syndrome former matrix or, equivalently, the symbolic parity-check matrix, leads to codes with smaller syndrome former constraint lengths with respect to the best solutions available in the literature. We provide theoretical lower bounds on the syndrome former constraint length for the most relevant families of SC-LDPCCCs, under constraints on the minimum length of cycles in their Tanner graphs. We also propose new code design techniques that approach or achieve such theoretical limits.

Hindering reaction attacks by using monomial codes in the McEliece cryptosystem
Proc. IEEE ISIT 2018
Autore/i: Santini, Paolo; Baldi, Marco; Cancellieri, Giovanni; Chiaraluce, Franco
Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: In this paper we study recent reaction attacks against QC-LDPC and QC-MDPC code-based cryptosystems, which allow an opponent to recover the private parity-check matrix through its distance spectrum by observing a sufficiently high number of decryption failures. We consider a special class of codes, known as monomial codes, to form private keys with the desirable property of having a unique and complete distance spectrum. We verify that for these codes the problem of recovering the secret key from the distance spectrum is equivalent to that of finding cliques in a graph, and use this equivalence to prove that current reaction attacks are not applicable when codes of this type are used in the McEliece cryptosystem.

Time-invariant spatially coupled low-density parity-check codes with small constraint length
Proc. IEEE BlackSeaCom 2016
Autore/i: Baldi, Marco; Battaglioni, Massimo; Chiaraluce, Franco; Cancellieri, Giovanni
Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: We consider a special family of spatially coupled low-density parity-check (SC-LDPC) codes, that is, time-invariant low-density parity-check convolutional (LDPCC) codes, which are known in the literature for a long time. Codes of this kind are usually designed by starting from quasi-cyclic (QC) block codes, and applying suitable unwrapping procedures. We show that, by directly designing the LDPCC code syndrome former matrix without the constraints of the underlying QC block code, it is possible to achieve smaller constraint lengths with respect to the best solutions available in the literature. We also find theoretical lower bounds on the syndrome former constraint length for codes with a specified minimum length of the local cycles in their Tanner graphs. For this purpose, we exploit a new approach based on a numerical representation of the syndrome former matrix, which generalizes over a technique we already used to study a special subclass of the codes here considered.

Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: We consider a special family of spatially coupled low-density parity-check (LDPC) codes known as LDPC convolutional codes and propose a design technique based on symbolic hyper-graphs aimed at achieving good codes with small syndrome former memory order. We define conditions on the minimum syndrome former memory order that must be imposed in order to avoid short local cycles in the codes Tanner graphs and to achieve good minimum distance. Code design examples are provided, accompanied by error rate performance assessments based on Montecarlo simulations.

Low-rate LDPC Convolutional Codes with Short Constraint Length
Proc. International Conference on Software, Telecommunications and Computer Networks (SoftCOM 2015)
Autore/i: Baldi, Marco; Cancellieri, Giovanni
Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: We study a family of LDPC convolutional codes having code rate of the type 1/a, and analyze their minimum distance and local cycles length properties. We consider some low weight codewords that are known from the literature, and are easily obtained from the symbolic parity-check matrix of these codes. Starting from the structure of such codewords, we follow a twofold approach: i) we exploit graph-based techniques to design these codes with the aim to maximize their minimum distance while keeping the syndrome former constraint length as small as possible and ii) we provide a simple form for their generator matrices that allows to perform exhaustive searches through which we verify that the code design actually reaches its target. We also estimate the normalized minimum distance multiplicity for the codes we consider, and introduce the notion of symbolic graphs as a new tool to study the code properties.

Sparse generator matrices for some families of quasi-cyclic low-density parity-check codes
Proc. SoftCOM 2014
Autore/i: Baldi, Marco; Cancellieri, Giovanni; Chiaraluce, Franco
Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: In this paper, we provide a general form for sparse generator matrices of several families of Quasi-Cyclic Low-Density Parity-Check codes. Codes of this kind have a prominent role in literature and applications due to their ability to achieve excellent performance with limited complexity. While some properties of these codes (like the girth length in their associated Tanner graphs) are well investigated, estimating their minimum distance is still an open problem. By obtaining sparse generator matrices for several families of these codes, we prove that they are also Quasi-Cyclic Low-Density Generator Matrix codes, which is an important feature to reduce the encoding complexity, and provides a useful tool for the investigation of their minimum distance.

Array Convolutional Low-Density Parity-Check Codes
IEEE COMMUNICATIONS LETTERS
Autore/i: Baldi, Marco; Cancellieri, Giovanni; Chiaraluce, Franco
Classificazione: 1 Contributo su Rivista
Abstract: This paper presents a design technique for obtaining regular time-invariant low-density parity-check convolutional (RTI-LDPCC) codes with low complexity and good performance. We start from previous approaches which unwrap a low-density parity-check (LDPC) block code into an RTI-LDPCC code, and we obtain a new method to design RTI-LDPCC codes with better performance and shorter constraint length. Differently from previous techniques, we start the design from an array LDPC block code. We show that, for codes with high rate, a performance gain and a reduction in the constraint length are achieved with respect to previous proposals. Additionally, an increase in the minimum distance is observed.

Classificazione: 3 Libro
Abstract: The book offers an original view on channel coding, based on a unitary approach to block and convolutional codes for error correction. It presents both new concepts and new families of codes. For example, lengthened and modified lengthened cyclic codes are introduced as a bridge towards time-invariant convolutional codes and their extension to time-varying versions. The novel families of codes include turbo codes and low-density parity check (LDPC) codes, the features of which are justified from the structural properties of the component codes. Design procedures for regular LDPC codes are proposed, supported by the presented theory. Quasi-cyclic LDPC codes, in block or convolutional form, represent one of the most original contributions of the book. The use of more than 100 examples allows the reader gradually to gain an understanding of the theory, and the provision of a list of more than 150 definitions, indexed at the end of the book, permits rapid location of sought information.

Interleaved product LDPC codes
IEEE TRANSACTIONS ON COMMUNICATIONS
Autore/i: Baldi, Marco; Cancellieri, Giovanni; Chiaraluce, Franco
Classificazione: 1 Contributo su Rivista
Abstract: Product LDPC codes take advantage of LDPC decoding algorithms and the high minimum distance of product codes. We propose to add suitable interleavers to improve the waterfall performance of LDPC decoding. Interleaving also reduces the number of low weight codewords, that gives a further advantage in the error floor region.

Progressive differences convolutional low-density parity-check codes
IEEE COMMUNICATIONS LETTERS
Autore/i: Baldi, Marco; Bianchi, Marco; Cancellieri, Giovanni; Chiaraluce, Franco
Classificazione: 1 Contributo su Rivista
Abstract: We present a new family of low-density paritycheck (LDPC) convolutional codes that can be designed using ordered sets of progressive differences. We study their properties and define a subset of codes in this class that have some desirable features, such as fixed minimum distance and Tanner graphs without short cycles. The design approach we propose ensures that these properties are guaranteed independently of the code rate. This makes these codes of interest in many practical applications, particularly when high rate codes are needed for saving bandwidth.We provide some examples of coded transmission schemes exploiting this new class of codes.

Finite-precision analysis of demappers and decoders for LDPC-coded M-QAM systems
IEEE TRANSACTIONS ON BROADCASTING
Autore/i: Baldi, Marco; Chiaraluce, Franco; Cancellieri, Giovanni
Classificazione: 1 Contributo su Rivista
Abstract: LDPC codes are state-of-art error correcting codes, included in several standards for broadcast transmissions. Iterative soft-decision decoding algorithms for LDPC codes reach excellent error correction capability; their performance, however, is strongly affected by finite-precision issues in the representation of inner variables. Great attention has been paid, in recent literature, to the topic of quantization for LDPC decoders, but mostly focusing on binary modulations and analysing finite precision effects in a disaggregrated manner, i.e., considering separately each block of the receiver. Modern telecommunication standards, instead, often adopt high order modulation schemes, e.g. M-QAM, with the aim to achieve large spectral efficiency. This puts additional quantization problems, that have been poorly debated in previous literature. This paper discusses the choice of suitable quantization characteristics for both the decoder messages and the received samples in LDPC-coded systems using M-QAM schemes. The analysis involves also the demapper block, that provides initial likelihood values for the decoder, by relating its quantization strategy with that of the decoder. A new demapper version, based on approximate expressions, is also presented, that introduces a slight deviation from the ideal case but yields a low complexity hardware implementation.

LDPC codes based on serially concatenated multiple parity-check codes
IEEE COMMUNICATIONS LETTERS
Autore/i: Baldi, Marco; Cancellieri, Giovanni; Carassai, A; Chiaraluce, Franco
Classificazione: 1 Contributo su Rivista
Abstract: This letter proposes a new class of serially concatenated codes that can be viewed as Low-Density Parity- Check (LDPC) codes. They are derived from Multiple Serially Concatenated Single Parity-Check (M-SC-SPC) codes, but they use different components, that we call Multiple Parity-Check (MPC) codes. In comparison with M-SC-SPC codes, the new scheme achieves better performance with similar complexity. The proposed codes can represent an alternative to the well-known family of Repeat Accumulate (RA) codes, being based on the same principles.

Iterative soft-decision decoding of binary cyclic codes
JOURNAL OF COMMUNICATION SOFTWARE AND SYSTEMS
Autore/i: Baldi, Marco; Cancellieri, Giovanni; Chiaraluce, Franco
Classificazione: 1 Contributo su Rivista
Abstract: Binary cyclic codes achieve good error correction performance and allow the implementation of very simple encoder and decoder circuits. Among them, BCH codes represent a very important class of t-error correcting codes, with known structural properties and error correction capability. Decoding of binary cyclic codes is often accomplished through hard-decision decoders, although it is recognized that soft decision decoding algorithms can produce significant coding gain with respect to hard-decision techniques. Several approaches have been proposed to implement iterative soft-decision decoding of binary cyclic codes. We study the technique based on “extended parity-check matrices”, and show that such method is not suitable for high rates or long codes. We propose a new approach, based on “reduced parity-check matrices” and “spread parity-check matrices”, that can achieve better correction performance in many practical cases, without increasing the complexity.

Design techniques of two-layer architectures for WDM optical networks
INTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS
Autore/i: Borella, A.; Cancellieri, Giovanni; Chiaraluce, Franco
Classificazione: 1 Contributo su Rivista
Abstract: A general method for designing multilayered WDM optical networks, based on the combined use of single- and multi-hop connection modes, is presented. It takes into account variable values for the number of users and wavelengths in each cluster. Closed form expressions are derived for the transmission capacity and the optimum number of channels for intra-cluster communications, either in the case of uniform or non-uniform traffic distribution. The analytical approach is particularly useful in the presence of constraints on the number of wavelengths, due to technological limits or non-linear phenomena, when sub-optimal solutions must be necessarily addressed. The proposed method is integrated with the adoption of well-known selection procedures, like simulated annealing or genetic algorithms, to reduce the computational effort.

PPM transmission over a photon counting channel: comparison among various transmission formats
EUROPEAN TRANSACTIONS ON TELECOMMUNICATIONS
Autore/i: Cancellieri, Giovanni; Chiaraluce, Franco; Gambi, Ennio
Classificazione: 1 Contributo su Rivista
Abstract: A detailed analysis for a variety of transmission formats suitable for photon communication systems is presented. More precisely, starting from the basic orthogonal pulse position modulation (PPM), here assumed as a reference, several alternative modulation schemes are discussed. They can be seen as extensions of the basic format or, equivalently, as particular cases of the most complete alphabet obtained by considering all the possible combinations of high and low levels in a transmission organized over slotted time intervals. The analysis is developed in comparative terms, looking at the three parameters which are usually invoked for performance evaluation, i.e. transmission capacity, cut-off rate and bit error rate. Closed form expressions are given in all the examined cases, stressing the role, as figures of merit, of the transmission efficiency and the bandwidth expansion factor. At a parity of the latter parameter, it is shown that the performance of basic PPM can be improved, even significantly, by resorting to the alternative transmission formats. In particular, they maintain the spectral occupancy within acceptable limits, whereas the bit error rate can be lowered using alphabet puncturation or asymmetric error correcting codes.

All-optical polarization modulator based on spatial soliton coupling
JOURNAL OF LIGHTWAVE TECHNOLOGY
Autore/i: Cancellieri, G.; Chiaraluce, F.; Gambi, E.; Pierleoni, P.
Classificazione: 1 Contributo su Rivista
Abstract: The possibility of realizing an all-optical polarization modulator is theoretically demonstrated. Basic device exploits the cross-phase modulation effect involving spatial solitons in a Kerr-like nonlinear material. It is shown that a weak wave (modulating signal) can be used to control a stronger wave (pump signal), in such a way to obtain a polarization switch, if their input phase difference is exactly equal to 90° and the two waves exhibit mutual orthogonal polarizations. Since the required relative phase may be difficult and sometimes impossible to maintain, an improved solution is then proposed which eliminates any effect due to random phase difference between the colliding solitons. It is based on the adoption of a suitable control device employing two additional nonlinear blocks excited by solitons with equal amplitude and linear polarization. The resulting field is then subjected to self-phase modulation. The structure is completed by a cascade of linear and nonlinear waveguides acting as proper soliton filters. This way, the behavior as an all-optical polarization modulator is ensured, even in the most critical input conditions, corresponding to a phase difference of 12.5° for our choice of the physical and geometrical parameters.

Abstract: The feasibility of AND, OR, and EX-OR functions based on the interaction of optical solitons is proved by use of a five-layer dielectric structure with a nonlinear core. With the exception of the OR logic gate, the design of these devices is rather flexible, offering a wide variety of choices with respect to both the geometrical parameters and the input power levels.

Abstract: A concatenation of Reed-Solomon and repetition codes with symbol interleaving is considered for applications in which the message length is limited and the probability of incorrect received symbols is high. An analysis is developed with reference to a Packet Radio Network, using Spread Spectrum modulation, simultaneously affected by random errors and burst errors. The results obtained are compared with those derived by numerical simulation. It is shown that a canonical formulation can be used for the case of full interleavers, but it cannot be applied to encoding schemes with partial interleavers. In the latter situation a modified, improved, approach is proposed.

Abstract: The Distributed Queue Dual Bus (DQDB) protocol with BandWidth Balancing (BWB) mechanism is unable to effectively support multiple priority levels that may be necessary for providing new services to network users. Thus, fair allocation of bandwidth among users is assured only in the case of one level of traffic priority. To overcome this limitation, this paper introduces a novel mechanism called Extended Counting BandWidth Balancing (ECBWB), which augments and enhances the operation of the current BWB mechanism. Simulation results, obtained under particularly severe traffic overload conditions, show that the proposed mechanism has better performance but minimal added complexity with respect to the current version of the protocol.

Abstract: In questo lavoro vengono presentate le principali caratteristiche e le relative limitazioni delle metodologie F.E.M. applicate all’analisi delle guide d’onda dielettriche a frequenze ottiche. In particolare, sono discusse le problematiche connesse alla scelta delle componenti di campo, del funzionale e del reticolo. Vengono inoltre analizzate le soluzioni più efficienti per la trattazione di domini illimitati e per l’eliminazione delle soluzioni spurie.
