把PKCY的破译归结为其等效密码体制的破译,建立了用矩阵方程组求等效秘密密钥的方法.研究了解该类矩阵方程组的算法.实现了PKCY的唯公开密钥快速破译.
At the same time, the deciphering of PKCY is attributed to the deciphering of its equivalent cryptosystem, and the method of finding the equivalent secret key by using matrix equation system is established.An algorithm for solving this kind of matrix equations is studied and PKCY-only public key deciphering is realized.
