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...

Threshold RSA for Dynamic and Ad-Hoc Groups
Abstract--We consider the use of threshold signatures in adhoc and dynamic groups such as MANETs ("mobile ad-hoc networks"). We first show that known threshold RSA signat...

On the Security of Some Nonrepudiable Threshold Proxy Signature Schemes
A (t, n) threshold proxy signature scheme enables an original signer to delegate the signature authority to a proxy group of n member such that t or more than t proxy signers can ...

On the Security of Two Threshold Signature Schemes with Traceable Signers
A (t, n) threshold signature scheme allows t or more group members to generate signatures on behalf of a group with n members, while any t−1 or less members cannot do the same th...

Fully Distributed Threshold RSA under Standard Assumptions
The aim of this article is to propose a fully distributed environment for the RSA scheme. What we have in mind is highly sensitive applications and even if we are ready to pay a pr...
