Elucidating the vulnerability of IC cards and establishing countermeasures
TOGAWA, Nozomu Professor (Faculty of Science and Engineering School of Fundamental Science and Engineering)
In the scan path design, “scan registers” are incorporated randomly into the LSI, so it was originally secret information that only the designer knew.We demonstrated that it is possible to decipher the cryptographic processing of LSI in IC cards by making use of the regularity...
