An RSA-based (t, n) Threshold Proxy Signature Scheme with Freewill Identities

In a t, n threshold proxy signature scheme, an original signer can authorize a proxy group with n proxy signers to generate a proxy signature on behalf of the original signer..

In this paper, we elabo- rate on the merits of SDVS schemes and proxy signature schemes to propose an efficient strong designated verifier proxy signature (SDVPS) scheme in which

In this paper, a new attack is proposed to show that, both in Hwang et al.’s and Sun’s schemes, the threshold proxy signatures can be forged by the cooperation of only one

claimed that Chien et al.’s scheme cannot meet the untraceability property of the blind signature later.. In this paper, we show that Hwang et al.’s claim is incorrect and Chien

She extended the threshold Mignotte scheme [7] in order to address the weighted access structure in which the set of participants is partitioned into several compartments, a
