A Lattice-Based Group Signature Scheme with Verifier-Local Revocation
Support of membership revocation is a desirable functionality for any group signature scheme. Among the known revocation approaches, verifier-local revocation (VLR) seems to be the most flexible one, because it only requires the verifiers to possess some up-to-date revocation information, but not the signers. All of the contemporary VLR group signatures operate in the bilinear map setting, and ...

متن کاملAn Efficient Proxy Signature Scheme with Revocation
A proxy signature allows a designated person, called a proxy signer, to sign the message on behalf of the original signer. Proxy signatures are very useful tools when one needs to delegate his/her signing capability to other party. A number of proxy signature schemes have been proposed and succeeded for proxy delegations, but the schemes are in defective in proxy revocations. In this paper, we ...
متن کاملAttribute Based Group Signature with Revocation
In real life, one requires signatures to be from people who fulfill certain criteria, implying that they should possess specific attributes. For example, Alice might want a signature from an employee in Bobs company who is a member in the IT staff, a senior manager within the biometrics team or at least a junior manager in the cryptography team. In such a case an Attribute Based Group Signature...
متن کاملEfficient Member Revocation in Group Signature Schemes
Group signature schemes allow a group member to sign messages anonymously on behalf of the group. During last decade, group signature schemes have been intensively investigated in the literature and applied to various applications. Especially, as noted in [3], the complexity of member deletion stands in the way of real world applications of group signatures. In this paper, we propose a group si...
