Key Agreement Protocol (KAP) Using Conjugacy and Discrete Logarithm Problems in Group Representation Level
The key agreement protocol based on infinite non-commutative group presentation and representation levels is proposed. Two simultaneous problems in group representation level are ...

Cryptanalysis of Group-Based Key Agreement Protocols Using Subgroup Distance Functions
Abstract. We introduce a new approach for cryptanalysis of key agreement protocols based on noncommutative groups. Our approach uses functions that estimate the distance of a group...
