An Area-Optimized and Power-Efficient CBC-PRESENT and HMAC-PHOTON

This paper introduces an area-optimized and power-efficient implementation of the Cipher Block Chaining (CBC) mode for ultra-lightweight block cipher, PRESENT, Keyed-Hash Message Authentication Code (HMAC)-expanded PHOTON by using a feedback path single in scheme. The proposed scheme is designed, taped out, integrated as System-on-a-Chip (SoC) 65-nm CMOS process. An experimental analysis comparison between conventional CBC-PRESENT/HMAC-PHOTON with basis performed. has 128-bit plaintext/text secret key, which have gate count 5683/20,698 low power consumption 1.03/2.62 mW throughput 182.9/14.9 Mbps at maximum clock frequency 100 MHz, respectively. overall improvement area dissipation 13/50.34% 14.87/75.28% when compared to design.
