Cluster virtual user system implementation method based on sandbox mechanism

Abstract

The invention relates to a cluster virtual user system implementation method based on a sandbox mechanism. A sandbox mechanism is applied to a cluster communication system composed of a plurality of terminal devices and a base station to form a cluster virtual user system; wherein the cluster virtual user system has a plurality of switchable modes, and different modes belong to different securitylevels respectively; meanwhile, the cluster virtual user system has a high priority level and a low priority level, the high priority authority belongs to a high security level, and the low priority authority belongs to a low security level; high-security-level program resources of the cluster virtual user system can access low-security-level program resources, and the low-security-level program resources are closed in a sandbox and cannot access external resources. The sandbox mechanism is applied to the trunking communication system, so that the potential safety hazard existing when the system is switched in networks of different modes or the priority of a user is switched can be well solved, and better protection is provided for data.

Description

technical field [0001] The invention relates to a cluster communication system, in particular to a method for realizing a cluster virtual user system based on a sandbox mechanism. Background technique [0002] The trunking communication system mainly provides production scheduling and command and control services for professionals working outdoors. It has been widely used in many fields such as railway transportation, communication, electric power, petroleum, forestry, and public security. Group calls and emergency calls can also be connected to the public network for communication. At the same time, it also provides users with reliable communication channels, different priority levels, dynamic networking and other functions. Different fields of use can be flexibly configured and used according to their own needs. , with great convenience. The same device will have different usage rules in different application scenarios. When the device works in a multi-mode and multi-leve...

Problems solved by technology

The same device will have different usage rules in different application scenarios. When the device works in a multi-mode and multi-level network, because the network is not controlled and the network devices are mixed, the command system does not have complete control over the network. The device may have other authentication forms or lack of authentication capabilities. If an application can access any resource, it may damage other resources in use or cause data damage, data leakage, etc., and the security of the system will be affected. Therefore, it is necessary to take some measures to ensure that the information will not be tampered with or leaked by unauthorized persons
