This book constitutes the refereed proceedings of the 6th International Conference on Cryptology in India, INDOCRYPT 2005, held in Bangalore, India in December 2005. The 31 revised full papers presented together with 1 invited paper were carefully reviewed and selected from 148 submissions. The papers are organized in topical sections on sequences, boolean function and S-box, hash functions, design principles, cryptanalysis, time memory trade-off, new constructions, pairings, signatures, applications, e-cash, and implementations.

Progress in Cryptology - INDOCRYPT 2005

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.

This book constitutes the refereed proceedings of the 4th International Conference on Cryptology in India, INDOCRYPT 2003, held in New Delhi, India in December 2003. The 29 revised full papers presented together with 2 invited papers were carefully reviewed and selected from 101 submissions. The papers are organized in topical sections on stream ciphers, block ciphers, Boolean functions, secret sharing, bilinear pairings, public key cryptography, signature schemes, protocols, elliptic curve cryptography and algebraic geometry, implementation and digital watermarking, and authentication.
