Topics in cryptology

Meer over het boek

This collection covers various topics in cryptography, showcasing significant advancements and research findings. It begins with an overview of the first 30 years of cryptographic hash functions and the NIST SHA-3 competition. The exploration of public-key cryptography includes breaking RSA-based PIN encryption with minimal queries and efficient decryption methods for small encryption exponents. The text discusses resettable public-key encryption in virtual environments, hybrid encryption's plaintext-awareness, and speed records for NTRU. It also highlights high-speed parallel software implementations and refinements of algorithms over Edwards curves. Anonymity in cryptographic systems is addressed through new constructions for anonymous HIBE and identity-based adaptations of the Diffie-Hellman protocol. The work on extended sanitizable signature schemes and side-channel attacks emphasizes vulnerabilities in cryptographic protocols. Countermeasures against these attacks are proposed, including unrolling cryptographic circuits and addressing fault attacks on EMV signatures. The collection further delves into cryptanalysis, with topics like linear cryptanalysis of reduced-round PRESENT and dependent linear approximations. Practical key recovery attacks and rebound attacks on reduced hash functions are also examined. Lastly, it discusses the security of CBC MACs and the verification of hash chains, contributing to the ongoing
