The invention provides a security remote control system and method for industrial equipment. The system comprises industrial equipment, a control terminal and a cloud platform, wherein a security module I is arranged in the industrial equipment, a security module II is inserted into or arranged in the control terminal, the cloud platform comprises a security access gateway, a management system, aCA certificate management system and a forwarding server, and a security module III is arranged in the security access gateway. In remote control, the industrial equipment and the security access gateway perform bidirectional identity authentication and key negotiation and create a first session key; the control terminal and the security access gateway perform bidirectional identity authenticationand key negotiation and create a second session key; the control terminal and the industrial equipment perform bidirectional identity authentication and key negotiation through the forwarding serverand then create a third session key; and the control terminal performs security remote control on the industrial equipment by using the third session key through the forwarding server.

The invention discloses an archive immediate calling trace management method. According to the method, a borrowing target is taken out through a preset automatic archive arrangement mechanism, direct contact between an archive applicant and an archive storage location is avoided, and therefore the situation that the archive applicant makes contact with archive files except the borrowing target is avoided. In this way, the method is beneficial for avoiding the situation that the archive borrower touches the archive files except the borrowing target after obtaining passage qualification, the pertinence of archive calling is improved, and therefore archiving safety is improved.

The invention discloses a method for updating group information dynamically in group service. The method includes: carries identification to the communication terminal on the network side, if passes, the network side sends group information updating application to the communication terminal, after the communication terminal side receives the group information updating application, carries identification to the network side, if passes, the communication terminal side carries on group information update; if not, the communication terminal side refuse the update application of group information. If the communication terminal side does not pass the identification, the network side abolishes the group information update to the communication terminal side.

The invention is suitable for the field of communication, and provides a system, a method, a device and an installation for filtering programs. The system comprises a plurality of network clients and at least a server transfer station in a network connection with the network clients and resource servers providing program contents. The server transfer station obtains the resource description information of the programs requested by the network client from the resource servers, and filters resources addresses of illegal programs in the resource description information. The network clients analyze the resource description information transmitted by the server transfer station after filtering the resources addresses of the illegal programs, further filter the illegal programs in the analyzed program information, and generate a program list allowed to be played. The embodiment of the invention carries out multi-stage filtration on the programs through the server transfer station and the network clients, ensures legal and health content of the programs, and is beneficial to reducing illegal incidents and incidents of violating discipline.

The present invention provides a safety communication system and method in a vehicle, comprising: a TSP platform, a central gateway, a domain controller and an ECU device; the TSP platform is connected to the central gateway through a network, and the central gateway is connected to one or more domain controllers through a network Connection, the domain controller and one or more ECU devices are connected through the vehicle bus; after the first identity authentication and key negotiation between the TSP platform and the central gateway, the first secure channel is established, and the TSP platform communicates with the central gateway through the first secure channel Encrypted communication; after the second identity authentication and key distribution between the central gateway and the domain controller, the second secure channel is constructed, and the central gateway conducts encrypted communication with the domain controller through the second secure channel; between the domain controller and the ECU device The third security channel is constructed after the third identity authentication and key distribution are performed, and the domain controller performs encrypted communication with the ECU device through the third security channel.
