A data management method comprises a first processing node that obtains a secure storage key based on a first external keying material corresponding to the first processing node, encrypts data corresponding to an application program in the first processing node, and sends encrypted data to a second processing node. The second processing node obtains a secure storage key based on a second external keying material corresponding to the second processing node, and decrypts the encrypted data that corresponds to the application program and that is sent by the first processing node. The second external keying material is the same as the first external keying material, whereby the second processing node and the first processing node may obtain a same secure storage key, and the second processing node may successfully decrypt the encrypted data that corresponds to the application program and that is sent by the first processing node.

Data management method, apparatus, and system, and storage medium

A method for mounting a network attached storage (NAS) device, and a digital media player are provided, which includes broadcasting a discovery message for searching a network attached storage NAS device; parsing a configuration response message, which is sent by the NAS device according to the discovery message, and obtaining configuration information of the NAS device; and mounting the NAS device according to the configuration information. According to the present invention, the automatic mounting of the NAS device is realized by discovering and obtaining the configuration information of the NAS device in the network, and personally-recorded-video-contents or downloaded media contents, where the personally-recorded-video-contents or the downloaded media contents are stored in the NAS device, can be played according to the selection of a user in the case that local data storage is not supported, so as to enable a digital home user to obtain a better user experience.
