Anonymity is one of the main concerns in group-oriented cryptography. However, most efforts, for instance, group signatures and ring signatures, are only made to provide anonymity ...
A group key agreement (GKA) protocol allows a set of users to establish a common secret via open networks. Observing that a major goal of GKAs for most applications is to establish...

To protect privacy in large systems, users must be able to authenticate against a central server without disclosing their identity to the network. Private identification protocols ...
As the core operation of many public key cryptosystems, group exponentiation is central to cryptography. Attacks on its implementation in embedded device setting is hence of great ...
A multisignature scheme for specified group of verifiers needs a group of signers' cooperation to sign a message to a specified group of verifiers that must cooperate to check...
