Abstract


Position-based cryptography has attracted lots of researchers’ attention. In the mobile Internet, there are lots of position-based security applications. For the first time, one new conception, positioning-protocol-based symmetric cryptography is proposed. Based on one secure positioning protocol, one symmetric model is proposed. In the model, positioning protocols are bound to symmetric cryptography tightly, not loosely. Moreover, we propose one concrete positioning-protocol-based symmetric scheme, its correctness is proved. To our best knowledge, it is the first positioning-protocol-based symmetric scheme.
