Positioning-Protocol-Based Digital Signature

Position-based cryptography has attracted many researchers’ attention. In mobile Internet, there are lots of position-based security applications. In the paper, one new conception, positioning-protocol-based digital signature is proposed. Based on a secure positioning protocol, one model of positioning-protocol-based digital signature is proposed. In the model, the positioning protocol is bound to digital signature tightly, not loosely. Further, we propose one concrete positioning-protocol-based digital signature scheme and its correctness is proved.
