Generalisation of Kipnis and Shamir Cryptanalysis of the HFE public key cryptosystem Year: 2007 Volume: 1 Issue: 12 3773 - 3776 Pages Authors: Omessaad Hamdi Ammar Bouallegue Sami Harari Abstract: In [4], Kipnis and Shamir have cryptanalised a version of HFE of degree 2. In this paper, we describe the generalization of this attack of HFE of degree more than 2. We are based on Fourier Transformation to acheive partially this attack. Keywords: Public cryptosystem cryptanalisis HFE.
