    摘要: An approach for protecting digital contents includes a content delivery phase wherein a client stores digital contents or retrieves them in streaming, transmits to a user device the digital content in a protected format along with an enabling code for enabling the user device to access or read the protected digital content. The approach includes a key generation phase in a DRM (Digital Right Management) server which derives at least one key for encrypting the digital contents. A key transmission phase involves the derived key being transmitted from the DRM server to the client. For decrypting the digital content, the user device requests the key from the DRM server, with the request including a key identification defined by the enabling code transmitted by the client to the user device which is used by the DRM server to derive the key for the user device.
