| Abstract(in English) | In this paper we describe an improvement of a fast DES implementation in software proposed by Biham at the 4-th Fast Software Encryption Workshop(FSE'97). That is, we propose a new algorithm which minimizes the number of instructions for computation of S-boxes, which is the factor dominating of the performance of Biham's implementation. Our algorithm is applicable to other functions used in other block ciphers. We can reduce the number of instructions for 1 round of DES from 1040 to 942. |
