Problems solved by technology
Obviously, for complex and changeable security environments, relying on uid alone to identify identities is not enough
And there is another fatal problem, that is, each user can run different task processes, and each task process will have the same uid. If socket communication is performed with such a series of task processes, there will always be only one identity that can be identified The same uid cannot distinguish different task processes at all, which is fatal enough in terms of security

The present invention provides a communication peer identity identification method, device and corresponding terminal, the method comprising: based on the socket connection established with the communication peer, obtaining the mandatory access control MAC identity of the communication peer; according to the MAC identity , to identify the identity of the communication peer; because the MAC identity is difficult to tamper with, in a system with a reasonable MAC policy setting, no user of any identity can modify the MAC identity of himself or others, and a MAC identity corresponds to a The task process, compared with the existing DAC method, can realize that multiple task processes under the same user have different security identities, so the present invention can effectively identify the identity of the communication peer in the socket connection, providing a guarantee system security key cornerstone.
Description
technical field [0001] The present invention relates to the field of mobile Internet, in particular, the present invention relates to a communication peer identification method, device and corresponding terminal. Background technique [0002] In the field of mobile Internet, the communication between software is very important. There are many popular communication methods at present, including: signal, pipeline, shared memory, android Binder mechanism, socket and so on. These IPC (Inter-Process Communication, inter-process communication) methods are all important communication methods between task processes. [0003] For the Socket communication method, it is not limited to the communication between local processes, and can fully support the communication between two or more terminals across the network. At this time, most of the applications are network applications, and when the socket is created as a Unix domain type When it is used, it is mainly used for communication b...
