  The certificateless public key cryptography (CL-PKC) setting, makes it possible to overcome the problems of the conventional public key infrastructure and the ID-Based public key cryptography, concurrently. A certificateless signcryption (CL-SC) scheme is an important cryptographic primitive which provides ...  Read More

An efficient certificateless signcryption scheme in the standard model

P. Rastegari; M. Berenjkoub

Volume 9, Issue 1 , January 2017, , Pages 3-16

  Certificateless public key cryptography (CL-PKC) is a useful method in order to solve the problems of traditional public key infrastructure (i.e., large amount of computation, storage and communication costs for managing certificates) and ID-based public key cryptography (i.e., key escrow problem), simultaneously. ...  Read More

Provably secure and efficient identity-based key agreement protocol for independent PKGs using ECC

M. Sabzinejad Farash; M. Ahmadian Attari

Volume 5, Issue 1 , January 2013, , Pages 55-70

  Key agreement protocols are essential for secure communications in open and distributed environments. Recently, identity-based key agreement protocols have been increasingly researched because of the simplicity of public key management. The basic idea behind an identity-based cryptosystem is that a public ...  Read More
