A secure wireless communication system integrating RSA, Diffie---Hellman PKDS, intelligent protection-key chains and a Data Connection Core in a 4G environment

摘要: In broadband wireless technology, due to having many salient advantages, such as high data rates, quality of service, scalability, security, mobility, etc., LTE-A currently has been one the trends system development. This provides several sophisticated authentication and encryption techniques enhance its security. However, still suffers from various attacks, like eavesdropping replay attacks. Therefore, in this paper, we propose a novel security scheme, called for 4G environment (Se4GE short), which an LTE-A-based integrates RSA Diffie---Hellman algorithms solve some LTE-A's drawbacks where stands LTE-Advance is system. The Se4GE end-to-end ciphertext transfer mechanism dynamically changes keys enforce transmission also produces logically connected random keys, intelligent protection-key chain, invokes two encryption/decryption provide users with broader demands services. analytical results show that higher level than
