First Experimental Result of Power Analysis Attacks on a FPGA Implementation of LEA
Yongdae Kim and Hyunsoo Yoon
Abstract
The lightweight encryption algorithm (LEA) is a 128-bit block cipher introduced in 2013. It is based on Addition, rotation, XOR operations for 32-bit words. Because of its structure,it is useful for several devices to achieve a high speed of encryption and low-power consumption.However, side-channel attacks on LEA implementations have not been examined.In this study, we perform a power analysis attack on LEA. We implemented LEA with 128-bit key size on FPGA in a straightforward manner. Our experimental results show that we can successfully retrieve a 128-bit master key by attacking a first round encryption.
