A secure wireless communication system by integrating RSA and Diffie-Hellman PKDS in 4G environments and an intelligent protection-key chain with a data connection core

In this paper, we propose a novel security scheme, called the security system with RSA and Diffie-Hellman algorithms for a 4G environment (Se4GE for short), which as an LTE-based system integrates the RSA and Diffie-Hellman algorithms to solve some of the security drawbacks of current 4G broadband wireless transmission. The Se4GE is an end-to-end ciphertext transfer mechanism which dynamically changes the encryption key to enhance the security of data transmission in a 4G wireless environment. The Se4GE also produces a large amount of connection random keys, called an intelligent protection-key chain, through a combination of encryption or decryption functions to provide users with broader demands for security services.
