The invention discloses an authentication switching method with privacy protection in an LTE (long term evolution)/LTE-A (LTE-advanced) network. After ME (mobile equipment) is accessed to the LTE/LTE-A network for the first time and successfully finishes access authentication with an AAA (authentication, authorizing and accounting) server, the AAA server generates a pseudonym set for the ME. When the ME needs to be switched to a new AP (access point) due to movement, only one unused pseudonym needs to be selected from the pseudonym set to perform identity authentication, the real identity of the ME does not need to be provided, so that leakage of a user identity and position privacy can be avoided, and anonymity and untraceability are realized. In the authentication switching process, key agreement is realized based on a Diffie-Hellman key exchange algorithm, the mutual authentication process is finished by hash function value verification, bilinear pairing operation is omitted, and authentication delay is reduced.

The invention discloses a combined handover authentication method and system used for goods escorting. The method is characterized by including the following steps that: (a) handover task information is pre-stored to a remote server; (b) handheld terminals transmit handover requests through a wireless network, detect geographic positions where signals are transmitted, and after conformation between the geographic positions and geographic positions pre-stored in the remote server are confirmed, opening codes are send back; (c) the handheld terminals open authentication interface display, and read several pieces of authentication tag information, are coupled with the remote server through the wireless network, and judge whether the obtained authentication tag information is correct or not through comparison, at the same time, download personnel information, and the method enters a manual authentication phase; and (d) physical handover is performed, and tag information of handover items is uploaded, and the handover terminates. The system can keep real-time communication with the remote server through the wireless network. According to the combined handover authentication method and system, an electronic fence is set, and information can be uploaded and downloaded on line, and the controllability, timeliness and reliability of a handover process can be ensured, and situations such as handover errors and omissions can be avoided; and the whole handover process has traceability, so that the whole handover process is safer and more reliable.

The invention discloses a quick switching authentication method for a low-orbit satellite communication network, which comprises the following steps that: a user terminal and a satellite terminal carry satellite inherent equipment information to register in a ground management center, and an original satellite selects a satellite switched by the user terminal according to the periodicity of the satellite to send a switching application request message; if successfully decrypting the authentication information of the user terminal, the switching satellite repliess a switching permission response message to the original satellite; the original satellite receives the switching permission response message of the switching satellite, generates switching preparation information and sends the switching preparation information to the user terminal; the user terminal receives the switching preparation message, determines the switching time, and sends a switching authentication request message to the switching satellite; the switching satellite receives the switching authentication request message and sends switching authentication response information to the user terminal; the user terminalreceives and verifies the switching authentication response information to complete a switching authentication process; According to the method, the security of the switching authentication process of the user terminal is ensured while the switching authentication time delay and the calculation overhead are reduced.

According to the data feedback method and system provided by the invention, after the mobile terminal calls out the authentication code, the pose data of the mobile terminal is acquired through the sensor of the mobile terminal, and the code scanning authentication state prompt signal of the authentication equipment is acquired through the signal acquisition equipment of the mobile terminal; whether the mobile terminal performs a code scanning authentication action or not is judged according to the pose data; and a code scanning authentication result is judged according to the acquired code scanning authentication state prompt signal, and the authentication result is displayed on a page of the mobile terminal. According to the method and the system, the code scanning authentication resultcan be fed back to the mobile terminal in real time in an offline state of the authentication equipment or the mobile terminal, and the mobile terminal is prompted to switch the authentication code after the code scanning is failed. Therefore, real-time feedback of data in an offline state is realized, and the user experience is improved.

The invention discloses a group pre-switching authentication method and device based on a trusted relay, and the method comprises the steps: carrying out the group authentication of a user terminal through the trusted relay, and recording the information of the user terminal passing the authentication to a pre-switching set; predicting the track of the user terminal in the pre-switching set to obtain a target base station of the user terminal; and comparing the current base station coverage range of the user terminal with the position information of the user terminal, and switching the user terminal to a target base station by using a trusted relay when the position of the user terminal exceeds the current base station coverage range. The group pre-switching technology and the trusted execution technology are combined, group switching can be rapidly and safely carried out, it is guaranteed that the 5G network can provide smooth and safe communication experience for users in the train running process, the switching problem of mass terminal devices in the current 5G network in the high-speed moving process is solved, and the user experience is improved. The method is high in applicability and safety, and switching overhead consumption is reasonable.

The invention discloses a network security authentication method. The method comprises the following steps: S1, establishing an IPSec communication system; S2, carrying out matrix-based key pre-distribution; and S3, establishing a secret sharing mechanism. The beneficial effects are as follows: the method is suitable for an IKEv2 initial exchange process improvement protocol in a wireless networkenvironment. The protocol has obvious performance advantages. The method can be applied to a wireless Internet network environment; in addition, a quick switching authentication method based on a neighbor graph and a pre-distribution method based on a matrix key are adopted, a rapid switching authentication scheme of the wireless Mesh network is provided, the problem of quick switching authentication failure caused by the mobility of the Mesh access point can be solved, through a self-healing group key distribution scheme, a safety channel does not need to be established between a group administrator and each group member to distribute personal secret information of the group members, and safety of storage overhead and communication overhead is achieved.
