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...
Today's headlines abound with the promised explosion of the Internet of things. Studies claim that there will be the existence of billions of internet connected devices in coming years. The small size and limited processing power of many connected devices could inhibit encryption and other robust security measure. Here cryptography plays a pivotal role. Also most of the devices available in the market...
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...
