Description
JST CREST Project “Mathematical Modelling for Next-Generation Cryptography” focuses on developing foundations for the mathematical modelling of the next-generation cryptographic systems, hereby addressing the risk brought by recent advances in cryptanalysis, in particular, by quantum computation and the physical attacks on the cryptographic devices (such as the power analysis). JST CRESTプロジェクト「次世代暗号に向けたセキュリティ危殆化回避数理モ デリング」は、最先端の数学理論を用い、予想困難な未来のセ キュリティ危殆化 回避数理モデリングを確立し、新しい暗号解読法、量子計算機等、想定される最 強の攻撃者をモデル化し、その攻撃に対する防御方法 を確立する。
