Digital Proxy Blind Signature Schemes Based on DLP and ECDLP
نویسندگان
چکیده
In a proxy signature scheme, a potential signer delegates his signing power to a proxy, who signs a message on behalf of the original signer. In a blind signature scheme, the signee cannot link the relationship between the blind message and the signature of the chosen message. That is, the signee cannot make a linkage between the blind signature and the identity of the requester. Therefore, it is very suitable for electronic commerce application. In this paper, on the basis of the Schnorr blind signature, we present two digital proxy blind signature schemes, which satisfy the security properties of both the blind signature and the proxy signature.

Analysis of Sun et al.'s linkability attack on some proxy blind signature schemes
The proxy blind signature scheme allows the designated proxy signer using the proxy secret key to generate a blind signature on behalf of the original signer. Tan et al. presented the DLP-based and ECDLP based blind signature schemes. Awasthi and Lal proposed a improved DLP-based scheme later. Recently, Sun et al. presented linkability attack on Tan et al. s and Awasthi–Lal s proxy blind signat...
متن کاملOn the Security of Some Proxy Blind Signature Schemes
A proxy blind signature scheme is a digital signature scheme which combines the properties of proxy signature and blind signature schemes. Recently, Tan et al. proposed two proxy blind signature schemes based on DLP and ECDLP respectively. Later, compared with Tan et al.’s scheme, Lal and Awasthi further proposed a more efficient proxy blind signature scheme. In this paper, we show that Tan et ...
متن کاملAn Enhanced Proxy Blind Signature with two Intractable Problems
A proxy blind signature scheme is combination of two signature schemes particularly proxy signature and blind signature. In this signature scheme the original signer delegate his/her signing authority to some other entity named proxy signer. The proxy signer signs the documents or messages, but he cannot be able to find any link between the blind signature and the identity of the signature requ...
متن کاملA New Proxy Blind Signature Scheme based on ECDLP
A proxy blind signature scheme is a special form of blind signature which allows a designated person called proxy signer to sign on behalf of two or more original signers without knowing the content of the message or document. It combines the advantages of proxy signature, blind signature and multi-signature scheme and satisfies the security properties of both proxy and blind signature scheme. ...

Proxy blind signature is a combination 0f both the properties of proxy signature and blind signature scheme. This scheme is useful in many applications like e-voting, e-payment and mobile agent environments. This paper presents a new proxy blind signature scheme based on discrete logarithm problem(DLP), which satisfies the secure properties of both the blind signature scheme and the proxy signa...
