Comparative Insights into State-of-the-Art Cryptographic Techniques and Design Approaches

The modern communication technology has experienced huge changes with the rapid growth of the Internet. This expansion has made human beings more dependent on it, but has also raised security issues during information exchange. While being transferred over a public network, attackers may monitor and capture the data packets if they are unencrypted. Consequently, the communication process may be interrupted and intercepted. Attackers can combine multiple methods to grab the transmitted data. Therefore, security of information is imperative prior transmission. Cryptography is a security measure to make data unintelligible to intruders. Numerous research studies have been conducted over the decades to introduce a variety of cryptography methods. Additionally, a number of analyses have been carried out to determine the optimal encryption technique based on specific characteristics, each with its own shortcomings. This prompts individuals to implement robust security measures. This paper provides a comprehensive analysis of contemporary cryptography methods, while also reviewing several existing related research efforts.
