Design A High Speed Novel Cryptography Using F.F Multiplier

Abstract

The requirement of information security on network has become more and more important. Cryptography is a method for providing information confidentiality, authenticity and integrity. There are various challenges to implement cryptography algorithm such as execution time, memory requirement, and computation power. Nowadays, digital communication protocols rely on cryptographic mechanisms to protect sensitive information from unauthorized access and modification. Cryptographic primitives, such as block and stream ciphers, are key components of many information security applications, employed to provide privacy, authentication, and data integrity. Cryptography must be able to provide highly efficient algorithms that combine strong security with optimal implementability.  This paper is concerned with the design of very large scale integration (VLSI) circuits for cryptographic functions and block cipher authenticated encryption modes.
