Problems solved by technology

[0012] The AB pairing information owned by device A is different from the BA pairing information owned by device B. The domain manager must generate two pairs of pairing information for the same pair (device A, device B), and both device A and device B must pass and The domain manager is contacted to obtain the pairing information of the device, which makes the processing process more complicated and consumes a lot of device resources

Abstract

The invention discloses a method for sharing paired information between two devices. The method comprises that a first device sends out a request message for obtaining the pairing information to a second device, and the pairing information is used for secure communication between the first device and the second device; the second device returns the pairing information to the first device when determining that the pairing information exists on the device according to the request message. The invention also discloses a communication device and a communication system. By adopting the invention, the identical pairing information can be utilized between the two devices to carry out the secure communication, thereby the processing flow is simplified, and device resources are saved.

Description

technical field [0001] The invention relates to the technical field of digital rights management, in particular to a method, device and system for sharing pairing information between devices. Background technique [0002] Digital Rights Management (DRM) mainly controls the use of digital content through rights restriction and content protection schemes, and protects the legitimate rights and interests of content owners. A user obtains digital content from a network or other devices, and the digital content is generally encrypted, and forms a content data packet together with other information (such as an encryption algorithm of the content). The license server (Rights Issuer, RI) is responsible for issuing the corresponding license for the content data package, and the license includes the content decryption key and the corresponding authority. A device can use digital content normally only if it has both the content data package and the license. The DRM device (DRM Agent)...
