A Group Signature Scheme with Efficient Membership Revocation for Middle-Scale Groups
This paper proposes a group signature scheme with efficient membership revocation. Though group signature schemes with efficient membership revocation based on a dynamic accumulator were proposed, the previous schemes force a member to change his secret key whenever he makes a signature. Furthermore, for the modification, the member has to obtain a public membership information of O( nN) bits, ...
متن کاملA Group Signature Scheme with Efficient Membership Revocation for Reasonable Groups
Though group signature schemes with efficient membership revocation were proposed, the previous schemes force a member to obtain a public membership information of O(`nN) bits, where `n is the length of the RSA modulus and N is the number of members joining and removed. In the scheme proposed in this paper, the public membership information has only K bits, where K is the number of members’ joi...
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 کاملGroup Signature Schemes with Membership Revocation for Large Groups
Group signature schemes with membership revocation have been intensively researched. However, signing and/or verification of some existing schemes have computational costs of O(R), where R is the number of revoked members. Existing schemes using a dynamic accumulator or a similar technique have efficient signing and verifications with O(1) complexity. However, before signing, the signer has to ...
