Digital Proxy Blind Signature Schemes Based on DLP and ECDLP
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 ...
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. ...
متن کاملThe new protocol blind digital signature based on the discrete logarithm problem on elliptic curve
In recent years it has been trying that with regard to the question of computational complexity of discrete logarithm more strength and less in the elliptic curve than other hard issues, applications such as elliptic curve cryptography, a blind digital signature method, other methods such as encryption replacement DLP. In this paper, a new blind digital signature scheme based on elliptic curve...
متن کاملRandomization Enhanced Blind Signature Schemes Based on RSA
In this letter, we show that Fan-Chen-Yeh’s blind signature scheme and Chien-Jan-Tseng’s partially blind signature scheme are vulnerable to the chosen–plaintext attack. We also show that both schemes can be modified so that the chosen– plaintext attack is impossible. But, still Chien-Jan-Tseng’s partially blind signature scheme is vulnerable. It fails to satisfy the partial blindness property. ...
متن کاملUntraceable Blind Signature Schemes Based on Discrete Logarithm Problem
Abstract. With the help of a blind signature scheme, a requester can obtain a signature on a message from a signer such that the signer knows nothing about the content of the messages and is unable to link the resulting message-signature pair; namely, a blind signature scheme can achieve both blindness and untraceability. Due to the above properties, the blind signature scheme can be used in cr...
