Design of password encryption model based on AES algorithm

Aiming at the demand for information system password encryption protection, this paper proposed a new set of password storage and transmission encryption model. In the process of password storage encryption, this paper built two keys included main key and working key, main key is responsible for the working key encryption, working key is responsible for the password encryption and updated automatically at regular intervals. In the process of password transmission encryption using AES algorithm, this paper improved the AES password transmission encryption process, adopted the method of password adding random number as a key to encrypted password. On this basis, this paper introduced RSA transmission encryption process, and compared AES with RSA in the process of transmission encryption. Experiments show that advanced AES process is faster than the RSA process and system has higher practicability and security.
