Embodiment Construction
[0043] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0044] Such as figure 1 , Public places need their own positioning servers, and have the ability to access and analyze wireless signals, that is, they need to be equipped with server wireless access points. There should be multiple identifiable WiFi hotspots in the public place, and mobile terminal users also have the ability to access and analyze wireless signals when passing through the public place.
[0045] The positioning server of the mobile terminal in a public place needs to locate the mobile terminal user passing through ...

The invention provides an authentication method between users of two adjacent mobile terminals, and belongs to the field of safety of a wireless communication network. Based on two adjacent user safety certificates, a pre-shared secret key, a trust facility or a public key system is not needed. Meanwhile, a non-parameter bayesian model is introduced to classify physical characteristics of a wireless data package to obtain a shared surrounding data package, so as to improve the accuracy of the two adjacent certificates and provides relatively flexible adjacent range control. Influences including loss of a signal path and the like can be caused by environments of middle-size and small-size public places, and a plurality of Wi-Fi (Wireless-Fidelity) accessing points in the public places cause that all clients cannot easily obtain same surrounding data package sequences, so that attackers outside the adjacent ranges cannot easily obtain all the shared surrounding data packages between a positioning server and the user of each mobile terminal. The method can be used for defending the attackers outside the adjacent ranges; meanwhile, private information including the positions of the users of the mobile terminals and the like is protected and the safety of the mobile terminal services based on the positions is improved.
Description
technical field [0001] The invention belongs to the field of wireless communication network security, in particular to an authentication method between adjacent mobile terminal users. Background technique [0002] With the rise of surrounding businesses and location-based mobile advertising, people's demand for navigation and positioning continues to increase, especially in some small and medium-sized public places, such as airport halls, railway station waiting halls, EMU trains, supermarkets, libraries , showrooms, department stores, etc. At the same time, with the popularization of smart phones to "everyone", the server wireless access points in public places push various information to mobile terminal users passing through the location, such as advertisements, discounts, promotions, safety reminders, warm reminders, etc. This requires the wireless access point of the server to be able to determine whether there is a mobile terminal user passing by within its vicinity, s...
