In the present era of e-world where security has got a larger weightage, cryptography has its role to play. Nowadays, the devices available in the market are of resource constrained type. Hence we need lightweight ciphers for the efficient encryption of data thereby increasing the performance. In this project a detailed study of HIGHT cryptographic algorithm is done which outperforms standard algorithms. HIGHT is an ISO Standard block cipher which has 64-bit block length and 128-bit key length. HIGHT was designed to be proper for the implementation in the low resource environment such as WSN, WBN, RFID tag or tiny ubiquitous devices. It is implemented on Spartan 6 FPGA evaluation kit and performance metrics are found out. A HIGHT cryptocore is being designed, characterized and implemented which will be a reference platform for hardware design engineers to model devices which require lightweight characteristics.
