Abstract: Microcontrollers are the small scale embedded devices that serves in most WSN in processing and communicating the data acquired by sensors. The AVR family encloses classy devices under 8 bit microcontroller category. Light weight crypto algorithms are designed to incorporate rational security in embedded devices. This study aspires in improvising the performance of 64 bit light weight block cipher HIGHT through software optimizations with AVRGCC compiler of Atmel Studio open source tool under windows platform. A modification on HIGHT algorithm is also proposed in this study to enhance its security level by additional manipulation on plain text prior to processing by the original algorithm. The coding is tailored towards decline in cost (memory requirement) and lift in performance (execution cycles, throughput). The obtained results of original HIGHT implementation are compared against a similar study. The modified HIGHT algorithm suggested in this study brings out augmented security with trifling drop off in unique attributes of embedded devices, the cost and performance.
