Embodiment Construction
[0048] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0049] In the past, in order to realize the update of the key, there is a third-party intervention and a large number of parameters are defined in the authentication protocol. The complexity of the authentication protocol is very high.
[0050] The quantum states used in many existing protocols are entangled states with more than three particles. However, the preparation of entangled states with more than three particles requires a lot of resources and is difficult to prepare, which increases the cost of the identity authentication process.
[0051] Moreover, in many existing protocols, after the identity authentication pro...
