This paper describes PayCash, an Internet payment system that was designed to offer strong security and privacy protection. This system is based on the concept of electronic cash,...
An identity-based signcryption scheme with (t, n) shared unsigncryption is proposed, which is the integration of the signcryption scheme, the (t, n) threshold scheme and zero know...
This paper describes a hardware architecture for modular multiplication operation which is efficient for bit-lengths suitable for both commonly used types of Public Key Cryptogra...
The efficiency of the core Galois field arithmetic improves the performance of elliptic curve based public key cryptosystem implementation. This paper describes the design and imp...
