Threshold proxy signatures

IEE Proceedings - Computers and Digital Techniques, 1999
A (t, n) threshold proxy signature scheme allows t or more proxy signers from a designated group of n proxy signers to sign messages on behalf of an original signer. The authors review both Zhang's threshold proxy signature scheme and Kim's threshold proxy signature scheme.

Multi-proxy Signature and Proxy Multi-signature Schemes from Bilinear Pairings

2004
In electronic world, proxy signature is a solution of delegation of signing capabilities. Proxy signatures can combine other special signatures to obtain some new types of proxy signatures. Due to the various applications of the bilinear pairings in cryptography, many pairing-based signature schemes have been proposed. In this paper, we propose a multi-

A Generic Construction of Proxy Signatures from Certificateless Signatures

2013 IEEE 27th International Conference on Advanced Information Networking and Applications (AINA), 2013
The primitive of proxy signatures allows the original signer to delegate proxy signers to sign on messages on behalf of the original signer. It has found numerous applications in distributed computing scenarios where delegation of signing rights is common.

Certificateless Proxy Signature and Its Extension to Blind Signature

2010 Fourth International Conference on Network and System Security, 2010
In this paper, a certificateless proxy signature scheme is introduced. The advantage of our scheme is that it can be extended into a certificateless proxy blind signature scheme very easily.

Threshold proxy signature schemes

1998
Delegation of rights is a common practice in the real world. Proxy signature schemes have been invented to delegate signing capability efficiently and transparently. In this paper, we present a new nonrepudiable proxy signature scheme. Nonrepudiation means the signature signers, both original and proxy signers, cannot falsely deny later that he ...

Efficient Generic Forward-Secure Signatures and Proxy Signatures

2008
We propose a generic method to construct forward-secure signature schemes from standard signature schemes. The proposed construction is more computationally efficient than previously proposed schemes. In particular, the key updating operation in the proposed scheme is orders of magnitude more computationally efficient than previous schemes, making it ...

Proxy Signature Schemes

2006 1ST IEEE Conference on Industrial Electronics and Applications, 2006
Throughout these years, there are plenty of enhanced proxy signature schemes being developed such as threshold proxy signatures, nominative proxy signatures, one-time proxy signatures, multi-proxy signature, proxy multi-signature and proxy blind signature.

Proxy Re-signatures in the Standard Model

2008
This paper studies proxy re-signature schemes. We first classify the expected security notions for proxy re-signature schemes with different properties. We then show how to attack on a recently proposed bidirectional scheme that is purported to be secure without random oracles, and discuss the flaw in their proof.

A Generic Construction for Proxy Signature Scheme

2011
In proxy signature, the original signer can delegate his signature power to the proxy signer. Due to the extensive application of proxy signature, some schemes have been presented, but there is not a general model for proxy signature scheme, especially for the scheme with good properties.
