Embodiment Construction

[0011] The technical solutions claimed in the present invention will be further described in detail in combination with specific embodiments.

[0012] A kind of communication method based on D-BUS communication protocol of the present embodiment, comprises D-Bus client, D-Bus service and the D-BuS bus that connects D-Bus client and D-Bus service, wherein to D-Bus Two levels of security permissions are set for each interface of the service, which are general permissions and advanced permissions.

[0013] When the D-Bus client sends a request to the D-Bus service interface, the D-Bus client first generates a first-level encryption key according to its own first-level key exchange algorithm and sends the first-level encryption key to D-Bus Service, when the D-Bus client sends a request, it encrypts the request according to the first-level encryption key, and the D-Bus service uses the first-level encryption key to decrypt and analyze the request of the D-Bus client and judge the ...

Abstract

The invention discloses a communication method based on a D-BUS communication protocol. According to the communication method, each interface of D-Bus services is set to have general authority or high authority according to security levels, so that the specific interfaces of the D-Bus service can be adapted to different security requirements, particularly when a D-Bus client requests high authority, the D-Bus client needs to be dynamically verified for many times, and thus a verification result is safer and more reliable, and communication security is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication method based on the D-BUS communication protocol. Background technique [0002] D-BUS is a free software project that provides a simple way for applications to communicate with each other, developed as part of the freedesktoporg project. D-Bus is implemented as a daemon. Users can execute several D-Bus entities, each entity is called a channel. Usually there is a privileged channel in the system called the system channel, and each user has a private entity. Users need private entities because the system channel will have access restrictions. [0003] However, from a security point of view, although D-Bus has made some security policy configurations, its security still needs to be further improved. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a highly secure communic...
