This paper describes the RTL design and hardware characterization of 64 bit light weight block cipher TWINE-80. Twine-80 is an inherently small hardware design with lesser number of gates and low power consumption compared to many of its counterparts. Twine has 36 rounds which reduces the chance of attacks. Hardware prototyping of twine cipher is done on Spartane6 FPGA. Structure of Twine is simpler...
Security plays a major role in the world of e-commerce. Cryptography is important for effective secure communication. The low-resource devices in the market needs lightweight ciphers for the hidden writing. In this paper a detailed study of HIGHT cryptographic algorithm is done. HIGHT is an ISO Standard block cipher which has 64-bit block length and 128-bit key length. HIGHT was designed to be proper...
The AES algorithm can be implemented in different styles at programming levels. The paper compares the hardware efficiency of different AES implementations with respect to their area, speed and power performance especially in two different styles -- one using controller and the other one is iterative method. These designs were described using Verilog HDL, simulated using Modelsim® and prototyped in...
