At CRYPTO 2000, a new public-key encryption based on braid groups was introduced. This paper demonstrates how to solve its underlying problem using the Burau representation. By thi...

Signcryption, first proposed by Zheng [4,5], is a cryptographic primitive which combines both the functions of digital signature and public key encryption in a logical single step,...
Abstract. Broadcast encryption provides a convenient method to distribute digital content to subscribers over an insecure broadcast channel. Traitor tracing is needed because some ...
We introduce a primitive called Hierarchical Identity-Coupling Broadcast Encryption (HICBE) that can be used for constructing efficient collusion-resistant public-key broadcast enc...
