Stamped Proxy Blind Signature Scheme
نویسندگان
چکیده
This paper presents two types of digital signature schemes combinely that are blind signature and proxy signature. In the proxy blind signature scheme, a signer other than the original signer signs the document as the agent of the original signer not knowing the meaning of the message. In this paper, an enhanced proxy blind signature is proposed, in which a time stamp approach is added to the proxy blind signature scheme which is based upon the discrete logarithm problem (DLP).

An Application of time stamped proxy blind signature in e-voting
Voting is a way for a voter to make a decision or express an opinion or to choose a candidate. E-voting (Electronic Voting) refers to both the electronic means of casting a vote and the electronic means of counting and publishing that votes. The E voting system has some specific advantages as compared to the traditional voting system. In this paper, a secure and efficient e-voting protocol is p...

متن کاملAnalysis of Some Attacks on Awasthi and Lal's Proxy Blind Signature Scheme
A proxy blind signature combines the properties of proxy signature and blind signature. Recently, Awasthi and Lal proposed a more efficient proxy blind signature based on the proxy signature scheme proposed by Mambo et al.. Later, Sun et al. and Das et al. gave some attacks on Awasthi and Lal’s scheme respectively. In this paper, we analyze the two attacks and we point out that those attacks do...
متن کاملA Proxy Blind Signature Scheme over Braid Groups
A proxy blind signature scheme is the combination of proxy signature and blind signature scheme. In 2009,Verma proposed a proxy blind signature scheme over braid groups. Verma claimed that the proposed scheme is secure against all possible security lapses and also satisfy all essential security attributes.This paper analyzes Verma’s proposed scheme and found that this scheme suffers with the se...
