A New digital signature scheme based on Stepwise Triangular Scheme (STS) is proposed. The proposed trapdoor has resolved the vulnerability of STS and secure against both Gr¨obner ...
The XTR public key system was introduced at Crypto 2000. Application of XTR in cryptographic protocols leads to substantial savings both in communication and computational overhead...
The McEliece cryptosystem is one of the few systems to be considered secure against attacks by Quantum computers. The original scheme is built upon Goppa codes and produces very l...
This paper reports security problems with improper implementations of an improved version of FEA-M (fast encryption algorithm for multimedia). It is found that an implementation-d...
At INDOCRYPT 2003 Abisha, Thomas, and Subramanian proposed two public key schemes based on word problems in free partially commutative monoids and groups. We show that both propos...
