Design and evaluation of novel hybrid quantum resistant cryptographic system for enhancing security in wireless body sensor networks

Data and information secrecy during storage or transmission has been preserved through the use of cryptography. Consequently, cryptography studies have also progressed from traditional Caesar cipher to the existing cryptographic protocols depending on quantum computing, starting with the latest modular arithmetic-based cryptosystems. The strength of modular arithmetic ciphers lies in the fact that they are computationally difficult to break, but with the advent of quantum computing, even these issues can be cracked with in polynomial time. Research on post-quantum cryptography began in response to this danger, with the goal of creating post-quantum algorithms that are immune to quantum computing. However, cryptographic methods confront a number of other problems, including, but not limited to, availability, integrity, and vulnerability. Despite the researchers’ successes, security is still a major issue for Quantum Computing. Because of its many advantages, cyberspace has quickly become the most common medium for disseminating information. Because of the exponential growth of science and technology, notably quantum computers, cyber security is now the top priority for the Internet and other wireless systems. The fundamental goal of this work is to create a Hybrid Quantum Cryptosystem that can be implemented in Wireless Body Sensor Networks. Using a series of comparisons with existing algorithms, we will determine how well our suggested hybrid algorithm operates in terms of key length, key generation time, decryption and encryption timings, and overall speed. The proposed approach attains 10.3 minimal rate of error, which outperforms the existing state-of-art techniques.
