Abstract. We describe implementations for solving the discrete logarithm problem in the class group of an imaginary quadratic field and in the infrastructure of a real quadratic fi...
Many applications using cryptographic hash functions do not require collision resistance, but some kind of preimage resistance. That's also the reason why the widely used SHA-...
We provide the first description of and security model for authenticated key exchange protocols with predicate-based authentication. In addition to the standard goal of session ke...
Hamsi is one of 14 remaining candidates in NIST's Hash Competition for the future hash standard SHA-3. Until now, little analysis has been published on its resistance to diffe...
We introduce a "generalized small inverse problem (GSIP)" and present an algorithm for solving this problem. GSIP is formulated as finding small solutions of f(x0, x1, . ...
