Implementation and Validation of Skien Cryptographic Hash Function Using High Speed Reversible Adders in Verilog Hdl

Abstract

Security has become a curial aspect in the design and use of computer system and network. Hash functions are used for many applications in cryptography mainly in digital signatures and message authentication code and in network security. Hash functions play a significant role in today's cryptographic applications. SHA (Secure Hash Algorithm) is a famous message compress standard used in computer cryptography, it can compress a long message to become a short message abstract. In this paper, SHA is implemented using Verilog HDL. In this paper encryption and decryption of the of the cipher text is implemented using SHA algorithm, where different types of adders are used in the process of encryption and compared. The proposed work deals with the construction of high speed adder circuits. Design and modeling of various adders like Ripple Carry Adder, Kogge Stone Adder, and Brent Kung Adder is done by using CMOS and GDI logic and comparative analysis is coated.
