2. Introduction to Key Services
2.1 ChinaDRM Client Development Kit (Android platform)
provides system software level and hardware level ChinaDRM mature client development kits (OPK, OEM Porting Kit) for SOC/terminal vendors, for integration testing and evaluation, reducing the learning and usage threshold of clients.
Software solution deliverables:
1) OPK integration guidance materials, including development guidance documents, header files, and library files for ChinaDRM OPK library adaptation to Android Mediadrm framework;
2) Supplementary information for software solution, including some configurations and proprietary files that need to be provided for the software solution.
Hardware solution deliverables:
1) OPK integration guidance materials, including development guidance documents, header files, and library files for OPK library adaptation to Android Mediadrm framework;
2) Supplementary information on hardware solutions, ChinaDRM Function Adaptor(REE)、ChinaDRM Function Adaptor(TEE)， This includes guidance on adapting ChinaDRM OPK library to ChinaDRM Function functionality under TEE CA/TA architecture, as well as defining ChinaDRM HW Runtime interface.
2.2 Client Integration Testing Environment and Provision Services
Provides a client integration testing environment and certificate provision services for SOC, terminal vendors, and video and audio service providers, enabling rapid testing, deployment, and application of ChinaDRM clients.
|
Client integration testing environment |
Provision service |
|
|
explanation |
Provide DemoAPP, ChinaDRM testing server, test cases, test streams, etc. to verify the basic functions of the client; You can refer to the DemoAPP to learn how to use ChinaDRM client, including provision, getLicense, encryption and decryption, etc |
Provide hosting and online download services for client certificates; Provide certificate usage statistics report (certificate usage, new increment, terminal type, etc.) |
|
value |
Verify the basic functions of the client (development phase), reduce the testing cycle for client products (evaluation phase), and build a terminal DRM function sampling environment (production phase) |
The terminal production line does not require certificate burning, and can purchase certificates as needed and download them in the air, achieving lifecycle management such as certificate ordering, management, download, and update at a lower cost |
|
deliverable |
1. DemoAPP； 2.ChinaDRM testing server (cloud based); 3. Encrypt the video stream; 4. Integration testing guidance document |
1. Certificate ordering and hosting services; 2. Certificate online downloading service |
2.3 ChinaDRM Client SDK
Existing terminals supporting DRM require mature SDK supply.
There are a large number of terminals in the market (mobile terminals, set-top boxes, televisions, etc.) that do not have ChinaDRM client capabilities, and in the short term or due to limitations in terminal basic capabilities, they cannot support CDRM through system upgrades and can only be integrated within the app
Using mature SDKs provided by industry DRM technology providers can avoid R&D investment and reduce DRM usage costs.
DTA collaborates with industry resources to provide a complete solution for DRM client SDK:
(1) Client SDK
• Features comply with ChinaDRM standards: supports obtaining client certificates and keys, obtaining licenses, and decrypting videos
• Security: Client private keys, license data, and other confidential data are protected by SoftTEE
• on-the-air interface provision: DRM client keys and certificates support air interface insertion, reducing the complexity of DRM certificate burning
(2) Digital Certificate Services
• Certificate supply: supports client key generation, certificate issuance services, as well as certificate lifecycle management such as certificate revocation and status queries
• Provision: Supports DRM client key and certificate air interface distribution and management
• Mutual trust: Communicate and trust with DRM servers
2.4 Two steps for SOC to implement ChinaDRM pre integration
(1) Integrated OPK (1.5 person months): DTA provides OPK, technical documentation, integrated testing environment, and technical support
(2) Assessment and certification (0.5 person month): ChinaDRM Lab provides DRM operating environment security assessment services, while DTA provides consultation
