A note on an identity-based ring signature scheme with signer verifiability
Recently, Herranz presented an identity-based ring signature scheme featuring signer verifiability where a signer can prove that he or she is the real signer by releasing an authorship proof. In this paper we show that this scheme is vulnerable to a key recovery attack in which a user’s secret signing key can be efficiently recovered through the use of two known ring signatures and their corres...
متن کاملAn improved identity-based ring signature scheme from bilinear pairings
Lin-Wu’s ID-based ring signature scheme from bilinear pairings is unreasonable. In this paper, we improve it, and obtain a reasonable ID-based ring signature scheme from bilinear pairings.
متن کاملA short identity-based proxy ring signature scheme from RSA
Identity-based proxy ring signature concept was introduced by Cheng et al. in 2004. This primitive is useful where the privacy of proxy signers is required. In this paper, the first short provably secure identity-based proxy ring signature scheme from RSA assumption has been proposed. In addition, the security of the proposed scheme tightly reduces to the RSA assumption, and therefore, the prop...
متن کاملForward Secure Identity Based Ring Signature Scheme for Images
Due to the advance of new technology data sharing has never been easier in this world. An accurate analysis on the shared data provides a group of benefits to both the society and individuals. Data sharing between two members or group of members must take into account several issues. They are efficiency, data integrity and privacy of data owner. To overcome this issue Ring signature concept is ...
متن کاملEfficient Identity Based Ring Signature
Identity-based (ID-based) cryptosystems eliminate the need for validity checking of the certificates and the need for registering for a certificate before getting the public key. These two features are desirable especially for the efficiency and the real spontaneity of ring signature, where a user can anonymously sign a message on behalf of a group of spontaneously conscripted users including t...
