Problems solved by technology

[0007] (4) After the device obtains the corresponding rights object, it must perform the corresponding tasks according to the rights. It cannot modify the rights, nor can it violate the provisions of the rights object file to decrypt the file and then spread it illegally.
If these behaviors cannot be effectively stopped, these illegal or invalid devices may spread the decrypted data widely, causing the entire system to be paralyzed

Embodiment

[0033] As shown in Figure 1, in order to prevent the information about the device from being falsified, the device legality authentication method that uses the device public key / private key to encrypt the device identity ID information includes the following steps:

[0034] The device side of the terminal:

[0035] 1) The device generates a public / private key pair and sends the public key to the server;

[0036] 2) The device re-encodes its original ID information to generate encoded ID information;

[0037] 3) The device encrypts the encoded ID information with the device private key to generate encrypted ID information and save it in the device memory.

[0038] Server side:

[0039] 1) The authentication center of the server receives the authentication request of the device;

[0040] 2) The server obtains the encrypted identity ID information stored in the device memory;

[0041] 3) The server decrypts the encrypted identity ID information with the device public key to o...

Description

technical field [0001] The invention relates to the field of information security, in particular to a method for device legality authentication or validity authentication of a digital copyright management system. Background technique [0002] With the development of digital media technology and computer network communication technology, the application of digital media is becoming more and more extensive. Digital media can be copied easily without any loss of quality and disseminated quickly and cheaply through the Internet. Securing digital rights for content providers is facing a serious test. How to implement effective copyright protection and information security in the network environment has become an urgent and realistic problem. In this case, a new technology, digital rights management (DRM), has emerged, which technically realizes the effective protection of copyright. [0003] The method of DRM implementation is as follows: [0004] (1) The server encrypts and ...
