摘要：
For the public key encryption scheme based on the ergodic matrices constructed by Pei et al., this paper proves that breaking this scheme is not harder than solving polynomial discrete logarithm problem on finite field applying the properties of ergodic matrices and linearization method. Thus, we show that their proof of security is not correct for this public key encryption scheme. ©, 2014, Tien Tzu Hsueh Pao/Acta Electronica Sinica. All right reserved.
