Abstract
A method for processing cipher change failure comprises: storing a record's error information when a cipher change of ciphertext data in the record fails, the error information comprising an identifier of the record and a failure cause; determining a retry strategy based on the stored failure cause; and employing the retry strategy to reperform the cipher change of the ciphertext data in the record having the identifier.
