Download or read book Design and Analysis of RC4-like Stream Ciphers [electronic Resource] written by Matthew E. McKague and published by University of Waterloo. This book was released on 2005 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: RC4 is one of the most widely used ciphers in practical software applications. In this thesis we examine security and design aspects of RC4. First we describe the functioning of RC4 and present previously published analyses. We then present a new cipher, Chameleon which uses a similar internal organization to RC4 but uses different methods. The remainder of the thesis uses ideas from both Chameleon and RC4 to develop design strategies for new ciphers. In particular, we develop a new cipher, RC4B, with the goal of greater security with an algorithm comparable in simplicity to RC4. We also present design strategies for ciphers and two new ciphers for 32-bit processors. Finally we present versions of Chameleon and RC4B that are implemented using playing-cards.
Book Synopsis Stream Ciphers in Modern Real-time IT Systems by : Alexandr Alexandrovich Kuznetsov
Download or read book Stream Ciphers in Modern Real-time IT Systems written by Alexandr Alexandrovich Kuznetsov and published by Springer Nature. This book was released on 2021-11-19 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the most complete description, analysis, and comparative studies of modern standardized and most common stream symmetric encryption algorithms, as well as stream modes of symmetric block ciphers. Stream ciphers provide an encryption in almost real-time regardless of the volume and stream bit depth of converted data, which makes them the most popular in modern real-time IT systems. In particular, we analyze the criteria and performance indicators of algorithms, as well as the principles and methods of designing stream ciphers. Nonlinear-feedback shift registers, which are one of the main elements of stream ciphers, have been studied in detail. The book is especially useful for scientists, developers, and experts in the field of cryptology and electronic trust services, as well as for the training of graduate students, masters, and bachelors in the field of information security.
Book Synopsis RC4 Stream Cipher and Its Variants by : Goutam Paul
Download or read book RC4 Stream Cipher and Its Variants written by Goutam Paul and published by CRC Press. This book was released on 2011-11-16 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: RC4 Stream Cipher and Its Variants is the first book to fully cover the popular software stream cipher RC4. With extensive expertise in stream cipher cryptanalysis and RC4 research, the authors focus on the analysis and design issues of RC4. They also explore variants of RC4 and the eSTREAM finalist HC-128. After an introduction to the vast field of cryptology, the book reviews hardware and software stream ciphers and describes RC4. It presents a theoretical analysis of RC4 KSA, discussing biases of the permutation bytes toward secret key bytes and absolute values. The text explains how to reconstruct the secret key from known state information and analyzes the RC4 PRGA in detail, including a sketch of state recovery attacks. The book then describes three popular attacks on RC4: distinguishing attacks, Wired Equivalent Privacy (WEP) protocol attacks, and fault attacks. The authors also compare the advantages and disadvantages of several variants of RC4 and examine stream cipher HC-128, which is the next level of evolution after RC4 in the software stream cipher paradigm. The final chapter emphasizes the safe use of RC4. With open research problems in each chapter, this book offers a complete account of the most current research on RC4.
Book Synopsis Analysis and Design of Stream Ciphers by : Rainer A. Rueppel
Download or read book Analysis and Design of Stream Ciphers written by Rainer A. Rueppel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now a decade since the appearance of W. Diffie and M. E. Hellmann's startling paper, "New Directions in Cryptography". This paper not only established the new field of public-key cryptography but also awakened scientific interest in secret-key cryptography, a field that had been the almost exclusive domain of secret agencies and mathematical hobbyist. A number of ex cellent books on the science of cryptography have appeared since 1976. In the main, these books thoroughly treat both public-key systems and block ciphers (i. e. secret-key ciphers with no memo ry in the enciphering transformation) but give short shrift to stream ciphers (i. e. , secret-key ciphers wi th memory in the enciphering transformation). Yet, stream ciphers, such as those . implemented by rotor machines, have played a dominant role in past cryptographic practice, and, as far as I can determine, re main still the workhorses of commercial, military and diplomatic secrecy systems. My own research interest in stream ciphers found a natural re sonance in one of my doctoral students at the Swiss Federal Institute of Technology in Zurich, Rainer A. Rueppe1. As Rainer was completing his dissertation in late 1984, the question arose as to where he should publish the many new results on stream ciphers that had sprung from his research.
Book Synopsis Design of Stream Ciphers and Cryptographic Properties of Nonlinear Functions by : Yassir Nawaz
Download or read book Design of Stream Ciphers and Cryptographic Properties of Nonlinear Functions written by Yassir Nawaz and published by . This book was released on 2007 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Block and stream ciphers are widely used to protect the privacy of digital information. A variety of attacks against block and stream ciphers exist; the most recent being the algebraic attacks. These attacks reduce the cipher to a simple algebraic system which can be solved by known algebraic techniques. These attacks have been very successful against a variety of stream ciphers and major efforts (for example eSTREAM project) are underway to design and analyze new stream ciphers. These attacks have also raised some concerns about the security of popular block ciphers. In this thesis, apart from designing new stream ciphers, we focus on analyzing popular nonlinear transformations (Boolean functions and S-boxes) used in block and stream ciphers for various cryptographic properties, in particular their resistance against algebraic attacks. The main contribution of this work is the design of two new stream ciphers and a thorough analysis of the algebraic immunity of Boolean functions and S-boxes based on power mappings.

Book Synopsis Domain Specific High-Level Synthesis for Cryptographic Workloads by : Ayesha Khalid
Download or read book Domain Specific High-Level Synthesis for Cryptographic Workloads written by Ayesha Khalid and published by Springer. This book was released on 2019-03-28 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an in-depth study of the design and challenges addressed by a high-level synthesis tool targeting a specific class of cryptographic kernels, i.e. symmetric key cryptography. With the aid of detailed case studies, it also discusses optimization strategies that cannot be automatically undertaken by CRYKET (Cryptographic kernels toolkit. The dynamic nature of cryptography, where newer cryptographic functions and attacks frequently surface, means that such a tool can help cryptographers expedite the very large scale integration (VLSI) design cycle by rapidly exploring various design alternatives before reaching an optimal design option. Features include flexibility in cryptographic processors to support emerging cryptanalytic schemes; area-efficient multinational designs supporting various cryptographic functions; and design scalability on modern graphics processing units (GPUs). These case studies serve as a guide to cryptographers exploring the design of efficient cryptographic implementations.

Book Synopsis New Stream Cipher Designs by : Matthew Robshaw
Download or read book New Stream Cipher Designs written by Matthew Robshaw and published by Springer Science & Business Media. This book was released on 2008-07-16 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This state-of-the-art survey presents the outcome of the eSTREAM Project, which was launched in 2004 as part of ECRYPT, the European Network of Excellence in Cryptology (EU Framework VI). The goal of eSTREAM was to promote the design of new stream ciphers with a particular emphasis on algorithms that would be either very fast in software or very resource-efficient in hardware. Algorithm designers were invited to submit new stream cipher proposals to eSTREAM, and 34 candidates were proposed from around the world. Over the following years the submissions were assessed with regard to both security and practicality by the cryptographic community, and the results were presented at major conferences and specialized workshops dedicated to the state of the art of stream ciphers. This volume describes the most successful of the submitted designs and, over 16 chapters, provides full specifications of the ciphers that reached the final phase of the eSTREAM project. The book is rounded off by two implementation surveys covering both the software- and the hardware-oriented finalists.

Download or read book Selected Papers from the 12th International Networking Conference written by Bogdan Ghita and published by Springer Nature. This book was released on 2021-01-04 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proceedings includes a selection of papers covering a range of subjects focusing on topical areas of computer networks and security with a specific emphasis of novel environments, ranging from 5G and virtualised infrastructures to Internet of things, smart environments and cyber security issues. Networking represents the underlying core of current IT systems, providing the necessary communication support for complex infrastructures. Recent years have witnessed a number of novel concepts moving from theory to large scale implementations, such as Software Defined Networking, Network Function Virtualisation, 5G, smart environments, and IoT. These concepts change fundamentally the paradigms used in traditional networking, with a number of areas such as network routing and system or business security having to adjust or redesign to accommodate them. While the benefits are clear, through the advent of new applications, use cases, improved user interaction and experience, they also introduce new challenges for generic network architectures, mobility, security, traffic engineering.

Book Synopsis Cryptanalysis of Lightweight Cryptographic Algorithms by : Mohammad Ali Orumiehchiha
Download or read book Cryptanalysis of Lightweight Cryptographic Algorithms written by Mohammad Ali Orumiehchiha and published by . This book was released on 2014 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stream ciphers are symmetric cipher systems which provide confidentiality in many applications ranging from mobile phone communication to virtual private networks. They may be implemented effciently in software and hardware and are a preferred choice when dealing with resource-constrained environments, such as smart cards, RFID tags,and sensor networks. This dissertation addresses cryptanalysis of several stream ciphers, and a hash function based on stream cipher. Also, the thesis investigates the design principles and security of stream ciphers built from nonlinear feedback shift registers. In a design view, any cryptographic attack shows a weak point in the design and immediately can be converted into an appropriate design criterion. Firstly, this thesis focuses on the WG-7, a lightweight stream cipher. It is shown that thekey stream generated by WG-7 can be distinguished from a random sequence with a negligible error probability. In addition, a key-recovery attack on the cipher has been successfully proposed. Then, a security evaluation of the Rakaposhi stream cipher identifies weaknesses of the cipher. The main observation shows that the initialisation procedure has a sliding property. This property can be used to launch distinguishing and key-recovery attacks. Further, the cipher is studied when the registers enter short cycles. In this case, the internal state can be recovered with less complexity than exhaustive search. New security features of a specific design based on nonlinear feedback shift registers have been explored. The idea applies a distinguishing attack on linearly filtered nonlinear feedback shift registers. The attack extends the idea on linear combinations of linearly filtered nonlinear feedback shift registers as well. The proposed attacks allow the attacker to mount linear attacks to distinguish the output of the cipher and recover its internal state. The next topic analyses a new lightweight communication framework called NLM-MAC. Several critical cryptographic weaknesses leading to key-recovery and forgery attack have been indicated. It is shown that the adversary can recover the internal state of the NLM generator. The attacker also is able to forge any MAC tag in real time. The proposed attacks are completely practical and break the scheme. Another part demonstrates some new cryptographic attacks on RC4(n,m) stream cipher. The investigations have revealed several weaknesses of the cipher. Firstly, a distinguisher for the cipher is proposed. Secondly, a key-recovery attack uses a method to find the secret key in real time. Finally, the RC4-BHF hash function that is based on the well-known RC4 stream cipher is analysed. Two attacks on RC4-BHF have been developed. In the first attack, the adversary is able to find collisions for two different messages. The second attack shows how to design a distinguisher that can tell apart the sequence generated by RC4-BHF from a random one.
