In this paper, we propose a new block cipher HIGHT with 64-bit block length and 128-bit key length. It provides low-resource
hardware implementation, which is proper to ubiquitous computing device such as a sensor in USN or a RFID tag. HIGHT does
not only consist of simple operations to be ultra-light but also has enough security as a good encryption algorithm. Our hardware
implementation of HIGHT requires 3048 gates on 0.25 μm technology.
