Constructing Cryptographic Hash Functions from Fixed-Key Blockciphers
We propose a family of compression functions built from fixed-key blockciphers and investigate their collision and preimage security in the ideal-cipher model. The constructions ha...

Circular-Secure Encryption from Decision Diffie-Hellman
We describe a public-key encryption system that remains secure even encrypting messages that depend on the secret keys in use. In particular, it remains secure under a "key cy...

Improved Bounds on Security Reductions for Discrete Log Based Signatures
Despite considerable research efforts, no efficient reduction from the discrete log problem to forging a discrete log based signature (e.g. Schnorr) is currently known. In fact, ne...

Preimages for Reduced SHA-0 and SHA-1
In this paper, we examine the resistance of the popular hash function SHA-1 and its predecessor SHA-0 against dedicated preimage attacks. In order to assess the security margin of ...

Cryptanalysis of the GOST Hash Function
In this article, we analyze the security of the GOST hash function. The GOST hash function, defined in the Russian standard GOST 34.11-94, is an iterated hash function producing a ...

Key-Recovery Attacks on Universal Hash Function Based MAC Algorithms
Abstract. This paper discusses key recovery and universal forgery attacks on several MAC algorithms based on universal hash functions. The attacks use a substantial number of verif...
