The signcryption is a relatively new cryptographic technique that is supposed to fulfill the functionalities of encryption and digital signature in a single logical step. Several ...
An efficient signcryption scheme based on elliptic curve is proposed in this paper. The signcryption scheme combines digital signature and encryption functions. The proposed schem...
A directly public verifiable signcryption scheme is introduced in this paper that provides the security attributes of message confidentiality, authentication, integrity, non-repud...
Secure multicast represents the core component of many web and multimedia applications such as pay-TV, teleconferencing, real-time distribution of stock market price and etc. The ...
This paper presents a new identity based key agreement protocol. In id-based cryptography (introduced by Adi Shamir in [33]) each party uses its own identity as public key and rece...
