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.

In cryptography, ciphers is the technical term for encryption and decryption algorithms. They are an important sub-family that features high speed and easy implementation and are an essential part of wireless internet and mobile phones. Unlike block ciphers, stream ciphers work on single bits or single words and need to maintain an internal state to change the cipher at each step. Typically stream ciphers can reach higher speeds than block ciphers but they can be more vulnerable to attack. Here, mathematics comes into play. Number theory, algebra and statistics are the key to a better understanding of stream ciphers and essential for an informed decision on their safety. Since the theory is less developed, stream ciphers are often skipped in books on cryptography. This book fills this gap. It covers the mathematics of stream ciphers and its history, and also discusses many modern examples and their robustness against attacks. Part I covers linear feedback shift registers, non-linear combinations of LFSRs, algebraic attacks and irregular clocked shift registers. Part II studies some special ciphers including the security of mobile phones, RC4 and related ciphers, the eStream project and the blum-blum-shub generator and related ciphers. Stream Ciphers requires basic knowledge of algebra and linear algebra, combinatorics and probability theory and programming. Appendices in Part III help the reader with the more complicated subjects and provides the mathematical background needed. It covers, for example, complexity, number theory, finite fields, statistics, combinatorics. Stream Ciphers concludes with exercises and solutions and is directed towards advanced undergraduate and graduate students in mathematics and computer science.

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.

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.

The book is designed to be accessible to motivated IT professionals who want to learn more about the specific attacks covered. In particular, every effort has been made to keep the chapters independent, so if someone is interested in has function cryptanalysis or RSA timing attacks, they do not necessarily need to study all of the previous material in the text. This would be particularly valuable to working professionals who might want to use the book as a way to quickly gain some depth on one specific topic.

Secure message transmission is of extreme importance in today's information-based society. Stream encryption is a practically important means to this end. This monograph is devoted to a new aspect of stream ciphers, namely the stability theory of stream ciphers, with the purpose of developing bounds on complexity which can form part of the basis for a general theory of data security and of stabilizing stream-cipher systems. The approach adopted in this monograph is new. The topic is treated by introducing measure indexes on the security of stream ciphers, developing lower bounds on these indexes, and establishing connections among them. The treatment involves the stability of boolean functions, the stability of linear complexity of key streams, the period stability of key streams, and the stability of source codes. Misleading ideas about stream ciphers are exposed and new viewpoints presented. The numerous measure indexes and bounds on them that are introduced here, the approach based on spectrum techniques, andthe ten open problems presented will all be useful to the reader concerned with analyzing and designing stream ciphers for securing data.

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.
