Identity-Based Threshold Proxy Signature from Bilinear Pairings
Abstract. Delegation of rights is a common practice in the real world. We present two identitybased threshold proxy signature schemes, which allow an original signer to delegate he...

A Secure Nonrepudiable Threshold Proxy Signature Scheme with Known Signers
In the (t, n) proxy signature scheme, the signature, originally signed by a signer, can be signed by t or more proxy signers out of a proxy group of n members. Recently, an efficie...

An improvement of nonrepudiable threshold proxy signature scheme with known signers
In a (t, n) threshold proxy signature scheme, which is a variant of the proxy signature scheme, the proxy signature key is shared among a group of n proxy signers delegated by the ...

Original Signer's Forgery Attacks on Discrete Logarithm Based Proxy Signature Schemes
A proxy signature scheme enables a proxy signer to sign messages on behalf of the original signer. In this paper, we demonstrate that a number of discrete logarithm based proxy si...

A Time-stamping Proxy Signature Scheme Using Time-stamping Service
In current proxy signature schemes, an original signer delegates her signing capability to a proxy signer, and then the proxy signer can sign messages on behalf of the original si...

Improvement on Nominative Proxy Signature Schemes
In a nominative proxy signature scheme, an original singer delegates his signing power to a proxy signer, who generates a nominative signature on behalf of the original signer. In...

Efficient Generic Forward-Secure Signatures and Proxy Signatures
We propose a generic method to construct forward-secure signature schemes from standard signature schemes. The proposed construction is more computationally efficient than previous...

A secure method for signature delegation to mobile agents
This paper presents a novel method that allows the delegation of signature power to one or more entities that jointly play the role of a proxy signer. This work is different from ...

Cryptanalysis of Some Group-Oriented Proxy Signature Schemes
Abstract. A proxy signature scheme allows an entity to delegate its signing power to another entity. Since the notion of proxy signatures was first introduced, many proxy signatur...
