VLSI Implementation of Cryptographic Algorithms & Techniques: A Literature Review

Through the years, the flow of Data and its transmission have increased tremendously and so has the security issues to it. Cryptography in recent years with the advancement of VLSI has led to its implementation of Encryption and Decryption techniques, where the process of translating and converting plaintext into cypher text and vice versa is made possible. In this paper, the review of various aspects of VLSI's implementation of encryption and decryption are covered. To systemize the material, the information about topics such as Private Key Encryption, Index Technique, Blowfish Algorithm, DNA cryptography, and many more are reviewed. Ultimately, with this review, the basic understanding of different VLSI techniques of Encryption and Decryption can be studied and implemented.
