Security in devices in this connected world is becoming increasingly important. One of the main areas in security is maintaining integrity while sending data. This is solved using hash functions. For devices with limited processing capabilities, we need lightweight hashing functions. One such Hash Algorithm is Keccak which is a variant of SHA-3.The implementation of the Keccak algorithm is prominently basic gates which make it suitable for hardware implementation. In this paper, we suggest a modification to the original Keccak algorithm to reduce the area of implementation. This reduction in area in turn, is expected to provide a reduction in power consumption. The modified Keccak Algorithm is based on the original Keccak Algorithm as well as the Blake G Function.
