Abstract

The invention discloses a secure transmission method for a dynamic password. The method comprises the steps: a mobile terminal obtains user information from a third party application, uses the asymmetric key algorithm to generate a key pair according to the user information, and stores the generated key pair in the mobile terminal; the mobile terminal obtains its own unique identification information and sends the user information, the public key of the generated key pair, and the unique identification information of the mobile terminal to a server; the server establishes a mapping relationship table among the user information, the public key of the generated key pair, and the unique identification information of the mobile terminal that all pass the validity check, and sends a notice of success of mapping relationship establishment to the mobile terminal; and the mobile terminal receives the notice of success of mapping relationship establishment and continues to monitor all the short messages. The method and the system can overcome the technical problems that the dynamic password is easily intercepted, acquired, received or eavesdropped by the third party in the existing dynamic password encryption transmission process.

Description

technical field [0001] The invention belongs to the technical field of information security, and more specifically relates to a method and system for secure transmission of a dynamic password. Background technique [0002] With the development of dynamic password technology, dynamic password technology is widely used whether it is in e-commerce transactions or in other systems that require identity verification or authority verification and granting. The trend of blowout, the dynamic password SMS verification code (hereinafter referred to as SMS verification code) formed by the combination of dynamic password and mobile Internet terminal is being widely and more and more used, but, as we all know, the dynamic password in the SMS verification code is sent, The transmission and reception are all carried out in plain text, and the sender, transmission intermediary, and receiver of the SMS verification code cannot guarantee that the dynamic password will not be intercepted, obta...
