A Novel Approach of Network Security Using Genetic Algorithm

Abstract

This article focuses on providing security of sensitive information and message transmission using symmetric key cryptosystem based on genetic algorithm and combined with mathematical and bitwise operators to provide confidentiality, authenticity, integrity, and nonrepudiation of the messages. A plain text is encrypted using a private key and resizer parameter taken as input from the user to produce an intermediate cipher which is further encrypted using genetic algorithm and mathematical operations to obtain the final cipher. The level of complexity of encryption and the size of the final cipher text can be regulated using the resizer parameter. The final cipher is decrypted first to obtain an intermediate cipher, which in turn is decrypted using the private key to get back the plain text. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
