Title: Ciphering device and decoding device
Inventor: KABASHIMA SHOSUKE
IPC: H03M7/14
Filed: 2000-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a public key ciphering system in which the safety of ciphering is maintained while a normal user easily conducts deciphering. SOLUTION: The symbol Cs represents a matrix of m rows and n columns having two elements '1' in every row, and Cn a reversible matrix of M rows and M columns having two elements '1' in every row. A plain sentence vector ξis multiplied by a matrix Cn-1Cs and a random vector η in which the appearance probability of '1' is p is added to obtain a ciphered sentence z. Then, the matrix Cn-1Cs and the value p are defined as public keys and the matrices Cn and Cs are defined as secret keys. In order to decode, the ciphered sentence z is multiplied by Cn to obtain a vector b and a parity inspection equation b=CsS+Cnτ is defined. Then, the equation is solved with respect to the vectors S and τ by using a probabilistic search method such as belief propagation and the estimated value of the sentence ξ is obtained as the solution of S.
