Title: Communication and certification method by n-ary expressed cipher, its device and storage medium which stores communication and certification program by the n-ary expressed cipher
Inventor: TAKAGI TAKESHI
IPC: H04L9/30
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To greatly improve the decoding speed while maintaining nearly the same strength in comparison with the strength of a conventional RSA cipher and a Rabin cipher by decoding the value of the least significant digit in an N-ary method from ciphered sentence data and successively decoding the value of the most significant digit in the N-ary method using the value of the decoded least significant digit. SOLUTION: A data coupling processing section 35 performs the N-ary expression of K digits coupling the data of respective blocks so that the value of each digit of one N-ary number M(n) becomes the respective blocks Mi(0<=i<=K-1) of a divided plain sentence and delivers the N-ary number M(n) to a ciphering processing section 37. That is a decoding speed corresponding to this is greatly increased by using the N-ary expression in which an open key N is made as a basic number for the ciphering. Therefore, the decoding of the least significant digit by the N-ary expression is decoded by using the same decoding method as a conventional method and the most significant digit excluding the least significant digit expressed by the N-ary is decoded by solving a first degree congruence expression using the value of the decoded least significant digit.
