摘要：
A method includes receiving, in a data storage device, a request from a client computer for a portion of ciphertext stored in the data storage device, and providing, by a controller of the data storage device, the portion of the ciphertext to the client computer. The method also includes receiving, in the data storage device, an update token generated by the client computer from the portion of the ciphertext. The method further includes performing, by the controller of the data storage device, re-encryption of the ciphertext using the update token.
