A Secure Communication System with Multiple Encryption Algorithms

Information security is a necessary safeguard for mobile e-commerce and a secure communication system to obtain high quality secure communication in wireless environment is introduced, which is integrating three kinds of encryption algorithms including AES, RSA and CPRS chaos encryption. Secure communication framework based on three-layer encryption model is proposed: (1) AES layer of system code decrypt, system boot and the system self-destruct; (2) RSA layer of authentication, key negotiation and key management functions; (3) CPRS layer of communication data stream encryption and decryption. The implementation and optimization of the above-mentioned three kinds of algorithms are discussed. The experiments show the three kinds of encryption algorithms are safe and reliable to achieve a high degree of secure communication.
