由在有限的地上使用各态历经的矩阵和多项式的性质的最小的多项式,我们在场为关于在有限的地(TSEPEM ) 上的各态历经的矩阵的二方面的取幂问题的一个多项式时间算法,和分析算法的时空复杂性。根据这个算法,公钥计划不基于 TSEPEM 是安全的。
By using the minimal polynomial of ergodic matrix and the property of polynomial over finite field,we present a polynomial time algorithm for the two-side exponentiation problem about ergodic matrices over finite field (TSEPEM),and analyze the time and space complexity of the algorithm.According to this algorithm,the public key scheme based on TSEPEM is not secure.
