ID-based multi-proxy signature, proxy multi-signature and ...
The multi-proxy signature scheme was first proposed in 2000 . In a multi-proxy signature scheme, an original signer could authorize a proxy group as his proxy agent. Then only the cooperation of all the signers in the proxy group can generate the proxy signatures on behalf of the original signer.
ID-Based Directed Multi-Proxy Signature Scheme from ...
Abstract. In a multi-proxy signature scheme, an original signer delegates his signing power to a group ofproxy signers. Then the group of proxy signers cooperatively generates a multi-proxy signatureon behalf of the original signer; and any one can verify the validity of the multi-proxy signature.But, when the signed message is sensitive to the signature receiver, it is necessary to combinethe ......
ID-based multi-proxy multi-signature scheme from bilinear ...
Here, we propose an ID-based multi-proxy multi-signature scheme using bilinear pairing and replacing the cer-tificate generation of Li and Chen scheme [5], by delegation generation.

Efficient ID-Based Multi-proxy Signature Scheme from ...
In this paper, we first propose an identity (ID)-based signature scheme from bilinear pairing and show that such a scheme can be used to generate an ID-based aggregate signature.
ID-Based Threshold Proxy Signature Scheme from Bilinear ...
Secondly, we propose an identity-based multi-proxy multi-signature scheme without bilinear pairings, where identity-based multi-proxy signature and proxy multi-signature schemes are its special cases.
Efficient ID-Based Multi-proxy Signature Scheme from ...
With the exploit of bilinear pairing over elliptic curves, several ID-based multi-proxy signature schemes have been developed till now [5,9,17]. In this paper, we have proposed an ID-based multi-proxy signature, based on ‘ k-plus problem’.
Identity-Based Directed Signature Scheme without Bilinear ...
Such directed signature schemes are applicable in many situations where the signed message is sensitive to the receiver such as signature on medical records, tax information etc. However all the existing directed signature schemes in ID based setting uses bilinear pairings over elliptic curves....
 Efficient and Secure Pairing-free ID-based Directed Proxy ...
A directed proxy signature scheme is a kind of signature scheme in which the verification ability is controlled by the proxy signer. Although many identity-based proxy signature schemes have been proposed in the literature, only a few identity-based directed proxy signature schemes are available. However, it has been found that all these ......
Secure proxy signature schemes from the Weil pairing
A proxy signature scheme is a method which allows an original signer to delegate his signing authority to a designated person, called a proxy signer. Up to now, most of proxy signature schemes are based on the discrete logarithm problem. In this paper, we propose a proxy signature scheme and a threshold proxy signature scheme from the Weil pairing, and also provide a security proof....
