Mobile office security system and method supporting domain management

Abstract

The invention provides a mobile office security system and a method supporting domain management. The system comprises a system kernel, program executing domain environment, an intelligent operation system and an application program domain, wherein the system kernel supports the domain management, is built in a hardware common mode provided by an intelligent terminal platform and realizes the domain management on application programs, the program executing domain environment is built on the system kernel supporting the domain management, and realizes at least two domains on the basis of the naming space, the intelligent operation system is built in the first domain in the program executing domain environment, the programs and the domains are subjected to allocation and communication management through open domain management interfaces of the system kernel supporting domain management, and the interaction between programs is realized, the application program domain is created in a domain different from the first domain in the program executing domain environment by the intelligent operation system, and is used for operating application programs. The system and the method has the advantages that the secure forced isolation of the office applications is realized, the cross-domain communication between processes is realized, the secure isolation among three application executing environments of the operation system, the office application and the personnel application is ensured, and meanwhile, the cross-domain communication of the three-party process is also supported.

Description

technical field [0001] The invention belongs to the field of mobile office security, and relates to a mobile office security method, in particular to a mobile office security system and method supporting domain management. Background technique [0002] In the current field of smart machines based on the LINUX kernel, smart operating systems and application programs (including personal application programs) all run in separate program processes. Business processing often requires communication between multiple processes. At present, inter-process communication includes pipelines, semaphores, message queues, shared memory, sockets, etc., but these existing inter-process communication methods have their own characteristics and are suitable for different platforms. In the existing inter-process communication and the kernel of the LINUX smart machine system, there is no customized operation for specialization. It is a relatively general technical solution. Basically, all applica...
