| Research Abstract |
Side-channel attacks are methods, where attackers retrieve secret information by using physical phenomena leaked from cryptographic hardware such as power consumption and electromagnetic radiation. Exploring the attack limits of side-channel analysis, this research focused on the clarification of information leakage. We succeeded in deriving the theoretical bound for the amount of information leakage, and extended the understanding of the relationship between secret and random information handled in cryptology.
