    Multi-exponentiation algorithm based on binary GCD computation and its application to side-channel countermeasure

    A series of algorithms for evaluation of multi-exponentiation are proposed based on the binary greatest common divisor algorithm. The proposed algorithms are inversion free and have the capability to evaluate ...

    Universally composable secure TNC model and EAP-TNC protocol in IF-T

    This paper analyzes trusted network connect (TNC) protocols within the universally composable (UC) framework. We propose the first TNC model in the UC framework by first designing the TNC ideal functionality ℱTNC

    A new approach for UC security concurrent deniable authentication

    Deniable authentication protocols allow a sender to authenticate a message for a receiver, in a way which the receiver cannot convince a third party that such authentication ever took place. When we consider a...

    Provable efficient certificateless group key exchange protocol

    Certificateless public key cryptography (CL-PKC) avoids the inherent escrow of identity-based cryptography and does not require certificates to guarantee the authenticity of public keys. Based on CL-PKC, we pr...

    Security extension for the Canetti-Krawczyk model in identity-based systems

    The Canetti-Krawczyk (CK) model is a formalism for the analysis of key-exchange protocols, which can guarantee many security properties for the protocols proved secure by this model. But we find this model lac...
