Abstract

The invention relates to a key updating method and device as well as a storage medium. The method comprises the following steps, which are executed in the configuration by a computer, of receiving an updated key; and storing the updated key and an old key. The updated key and the old key are simultaneously stored, so that when the updated key is abnormal, the possibility of realization is provided for using the old key to operate, and a convenient low-cost technical scheme for solving the operation exception is provided.

Description

technical field [0001] The invention relates to the field of computers, in particular to a key updating method, device and storage medium. Background technique [0002] In traditional technologies, encryption and decryption algorithms can be used to process data content, so as to prevent unauthorized users from obtaining data content. If the encryption key and decryption key are the same or can be derived mathematically, then such an algorithm becomes a symmetric cryptographic algorithm. Conversely, if the encryption key and decryption key are different or not mathematically derivable, then it is called an asymmetric key. The computer system can restrict unauthorized users from operating the computer system by setting keys. Usually, the key of the computer system needs to be updated regularly, so as to prevent the key from being obtained abnormally due to its long validity period. [0003] In the process of realizing the traditional technology, the inventor found that the...
