New Transport Layer Security using Metaheuristics and New Key Exchange Protocol

Abstract

The easiness of data transmission is one of the information security flaws that needs to be handled rigorously. It makes eavesdropping, tampering and message forgery by malicious more simple. One of the protocols developed to secure communication between the client and the server consists of using Transport Layer Security (TLS). TLS is a cryptographic protocol that allows encryption using record protocol, authentication and data integrity. In this paper, a new TLS version is proposed, named Transport Layer Security with Metaheuristics (TLSM), which is based on a recently designed metaheuristic symmetric ciphering technique for data encryption, combined with hash function SHA-SBOX and a new method for private key exchange. Compared to the existing TLS versions, the suggested protocol outperform all of them in terms of level of security of the encrypted data, key management and execution time.
