In 2007, l-Invertible Cycles (lIC) was proposed by Ding et al. This is one of the most efficient trapdoors for encryption/signature schemes, and of the mixed field type for multivariate quadratic public-key cryptosystems. Such schemes fit on the implementation over low cost smart cards or PDAs. In 2008, Fouque et al. proposed an efficient attack against the lIC signature scheme by using Grobner basis algorithms. However, they only explicitly dealt with the odd case, i.e. l is odd, but the even case;, they only implemented their proposed attack in the odd case. In this paper, we propose an another practical attack against the lIC encryption/signature scheme. Our proposed attack does not employ Grobner basis algorithms, and can be applied to the both even and odd cases. We show the efficiency of the attack by using some experimental results. Furthermore, the attack can be also applied to the lIC-scheme. To the best of our knowledge, we for the first time show some experimental results of a practical attack against the lIC- scheme for the even case. |
