Abstract
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.
