— In this paper, we propose a new pairing-based proxy signature. Most remarkable point in our proposal is that our scheme realizes short signature. More concretely, the explicit ...
This paper will show that Hsu and Wu’s efficient nonrepudiable threshold proxy signature scheme with known signers and Yang, Tzeng and Hwang’s efficient nonrepudiable threshol...
This paper presents a novel method that allows the delegation of signature power to one or more entities that jointly play the role of a proxy signer. This work is different from ...
A proxy blind signature scheme is a digital signature scheme which combines the properties of proxy signature and blind signature schemes. Recently, Tan et al. proposed two proxy ...
In this paper we shall introduce a new electronic payment concept based on the popular direct debit payment model, entitled periodical payments. The direct debit model currently i...
