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...

The security of a strong proxy signature scheme with proxy signer privacy protection
In 1996, Mambo et al. first introduced the concept of a proxy signature scheme, and discussed the delegation of the signing capability to a proxy signer. In 2001, Lee et al. const...

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...

Proxy Cryptography Revisited
In this work we revisit and formally study the notion of proxy cryptography. Intuitively, various proxy functions allow two cooperating parties F (the “FBI”) and P (the “pro...

Revisiting Fully Distributed Proxy Signature Schemes
In a proxy signature scheme, a potential signer delegates his capabilities to a proxy signer, who can sign documents on behalf of him. The recipient of the signature verifies both...
