Account management system and account management method based on cloud service

Abstract

The invention relates to an account management system and an account management method based on cloud service. The account management system comprises a user terminal, a cloud server, and a secure transport protocol module connected between the user terminal and the cloud server. The account password is generated at the client side by executing the Hash algorithm twice according to the account number provided by the user, the original key material, a random number generated by a cloud server and the random number generated by a user side USB (Universal Serial Bus) Key, and the account password is stored in the cloud server after being encrypted by the user side USBKey, and when the user needs the account information, the user can read the account password information stored in the cloud server by inputting the account name and the account number. According to the method and the system provided by the invention, the account password with fixed length is generated by two times of execution of Hash algorithm, thus, the account password cannot be decrypted easily; the account password encrypted by the USBKey is stored in the cloud server, so that the security of the account password is ensured; and when the user needs the password, the user can directly read the password without memorizing the password, so that the password management is convenient and easy to carry out.
