This book constitutes the refereed proceedings of the 5th International Conference on Security and Cryptology for Networks, SCN 2006, held in Maiori, Italy in September 2006.The 24 revised full papers presented together with the abstract of an invited talk were carefully revised and selected from 81 submissions. The papers are organized in topical sections on distributed systems security, signature schemes variants, block cipher analysis, anonymity and e-commerce, public key encryption and key exchange, secret sharing, symmetric key cryptanalisis and randomness, applied authentication, and public key related cryptanalisis.
Distributed Systems Security: Foundations Edge Eavesdropping Games Universally Composable Simultaneous Broadcast Signature Schemes Variants Relations Among Security Notions for Undeniable Signature Schemes. Concurrent Blind Signatures Without Random Oracles Universal Designated Verifier Signatures Without Random Oracles or Non-black Box Assumptions Block Ciphers Analysis Understanding Two-Round Differentials in AES Related-Key Attacks on the Full-Round Cobra-F64a and Cobra-F64b. Anonymity and E-Commerce Constant-Size Dynamic k-TAA On Secure Orders in the Presence of Faults Balancing Accountability and Privacy Using E-Cash Public Key Encryption and Key Exchange About the Security of MTI/C0 and MQV Chosen-Ciphertext Secure Threshold Identity-Based Key Encapsulation Without Random Oracles A New Key Exchange Protocol Based on MQV Assuming Public Computations Secret Sharing Ideal Secret Sharing Schemes Whose Minimal Qualified Subsets Have at Most Three Participants Cheating Immune (2, n)-Threshold Visual Secret Sharing Rational Secret Sharing, Revisited Symmetric Key Cryptanalysis and Randomness On the Security of HMAC and NMAC Based on HAVAL, MD4, MD5, SHA-0 and SHA-1 Distinguishing Stream Ciphers with Convolutional Filters On Statistical Testing of Random Numbers Generators Applied Authentication Lightweight Email Signatures Shoehorning Security into the EPC Tag Standard …… Public Key Related Cryptanalysis Invited Talk Author Index
