Abstract

The Lightweight Encryption Algorithm (LEA) is a block cipher algorithm developed to provide confidentiality in high-speed environments, big data, cloud, and mobile devices. There is an issue that these security algorithms' modules must be small in area and power in order to be loaded onto resource constraint devices such as passive RFID. In this paper, for the first time in LEA which is one of the block ciphers, Bit-Serial technique is used to realize small area and power. Using Samsung 65nm process, we could obtain 2240GE which is 49.8% less in terms of area compared to the state-of-the-art area-optimized LEA-128. The IP designed in this paper can be applied as a security module to resource constraint devices.
