AboutAbout the lab
Examining the security of cryptography to protect information
The Igarashi Lab studies cryptanalysis, which evaluates the security of ciphers, and information security.
Its research background lists research on the security evaluation and analysis of symmetric-key cryptosystems since 2006.
The listed research fields include block ciphers, stream ciphers, hash functions, and random numbers.
Cryptographic implementation is also one of its research keywords.
