An Architecture-Independent Instruction Shuffler to Protect against Side-Channel Attacks

Embedded cryptographic systems, such as smart cards, require secure implementations that are robust to a variety of low-level attacks. Side-Channel Attacks (SCAs) exploits the information such as power consumption, electromagnetic radiation and acoustic leaking through the device to uncover the secret information. Attackers can mount successful attacks with very modest resources in a short time period. Therefore, many methods have been proposed to increase the security against SCA. Randomizing the execution order of the instructions that are independent, i.e., random shuffling is one of the most popular among them.
