Development of Next Generation Encryption Algorithm for Data Transmission in 3G/4G Network

Abstract

AbstractSecurity plays an important part in communication systems. This work focuses on Development of Next Generation Encryption Algorithm enhanced by using variable key cipher where a stream of sub keys of AES is generated from the original key with feedback from previous cipher block and each sub block is encrypted with different sub keys. The use of variable key cipher makes the system nonlinear and creates confusion in the use of keys.The above technique is projected to develop more resistance to attacks and structural analysis, thus increasing the complexity of the system. Performance of the system will be evaluated on the basic of Encryption time, Decryption time, throughput and CPU usage
