The Dual-key Matrix Encryption Algorithm Improvements In Pki Technology And Its Implementation

With coming of the knowledge economy age and rapid development of the information technology as well as the formation of the economic globalization, the transmission paths of information more and more counts on the telecom networks, especially Internet. We select the computer network securities as our study object and develop the studies through combining the network construction, the public system of cipher keys and cipher codes and modern electronic commercial platform. Positive trial is done in this area.The main contents of the thesis are as follows:1. Introduce the dual-key matrix encryption method, which is suitable for digital signature.2. Base on RSA algorithm ,we construct a dual-key matrix encryption method.3. Design a dual-key matrix algorithm4. Design a program for an enterprise, which will realize its cash-in business operation (such as selling books) through the telecom electronics platform .5. Application of dual-key matrix encryption method in this program.
