An Enriched Ciphering Method to Evaluate Performance of EEA2-algorithm for LTE Security

In order to address vulnerabilities in LTE security and the objective to strengthen the implementation of encryption and decryption algorithms in LTE, we proposed a method for integration of an algorithm with a dynamic matrix generation scheme of 16*16 elements during AES implementation. Implementing such algorithm eradicates the vulnerability that causes a hacker to access plain text. The vulnerability arises within the implementation of AES. This research explores Enriched Ciphering algorithm for number of scenarios based on function calls and time metrics that increases 3.9 times when there is a change in size of the plain text. We evaluated the proposed algorithm referred to as Enriched Ciphering Algorithm based on various use cases, including compression and decompression of cipher text that provides an extra layer of complexity to strengthen the security, and provides performance improvements of 13.9 percent when executing the Enriched Ciphering algorithm with big data size.
