Outline of Final Research Achievements

Cryptographic VLSI techniques have been established for assuring electromagnetic security with remarkably high tamper resistance against side-channel attacks. Three research items include: (1) On-chip detection of the proximate placement and approach of electromagnetic micro probes as the side-channel attack sensing technique, (2) integrated simulation techniques of electromagnetic coupling between the electromagnetic micro probe and on-chip side-channel sensors and also circuit operations, (3) positive usage of side-channel information for the authentication of cryptographic cores. These research items have been successfully completed and demonstrated with the fabricated integrated-circuit (IC) chips and prototype systems.
