A Bottleneck Attack on Crypton
Crypton is a 12-round blockcipher proposed as an AES candidate by C.H. Lim in 1998. In this paper, we present two bottleneck attacks on reduced round version of... -
Cryptanalysis of multivariate schemes
Multivariate Cryptography can be defined as public key cryptography based on the computational hardness of solving a system of polynomial equations in several... -
HFE and BDDs: A Practical Attempt at Cryptanalysis
HFE (Hidden Field Equations) is a public key cryptosystem using univariate polynomials over finite fields. It was proposed by J. Patarin in 1996. Well chosen... -
