【Abstract】 This article discusses the development of cryptography and presents the features and functions of the permutation matrix in the common algorithm. This paper emphasizes on a new permutation matrix and its features and functions. It gives the initial permutation matrix and the inverse initial permutation matrix’s generative algorithm. The algorithm has a high calculation speed, highlevel safety and reliability. The authors also provide the basic process and examples of the encryption and decipherment applying by this algorithm. This algorithm is applied to the Process and Interpretation of Well Detective Materials Workstation System, which is a project of the National Natural Science Fundation of China, and helps the system to improve its security and reliability.更多还原
