Abstract:
Position-based cryptography has attracted lots of researchers’ attention. In the mobile Internet, there are many position-based security applications. For the first time, one new conception, threshold proxy signature based on positions is proposed. Based on one secure positioning protocol, one model of threshold proxy signature based on positions is proposed. In the model, positioning protocols are bound to threshold proxy signature tightly, not loosely. Further, we propose one position-based threshold proxy signature scheme, its correctness is proved, and its security is analyzed. As far as we know, it is the first threshold proxy signature scheme based on positions.
