Embodiment 1

[0066] Embodiment 1: The dynamic password authentication system of this embodiment includes a client access terminal, a mobile phone bound with the user's account, and a network management server; wherein the client access terminal is connected to the network management server through the network, the The client access terminal can be a personal computer, a mobile phone, or an ATM terminal for transactions with a bank that the user currently conducts online transactions. The mobile phone includes an encryption module, which stores the user's OTP private key and at least one dynamic password. Algorithm; the network management server is also configured with user public keys and at least one dynamic password generation algorithm corresponding to the mobile phone terminal. The network management server can be a bank background system, a service provider system, etc.

[0067] See attached figure 2 , the user identity authentication method carried out through the above system is sp...

Embodiment 2

[0080] At this stage, the authentication algorithms adopted by different bank background systems and service provider systems may be different, but by pre-setting multiple algorithms in the network management server and mobile phones, multiple authentication algorithms can be easily realized without changing the system structure. Business and multi-platform applications provide convenience for users. At the same time, the update of the password system can be conveniently realized through the OTA (over the air) technology, thereby further improving the security of the system. Embodiment 2: The dynamic password authentication system of this embodiment includes a client access terminal, a mobile phone bound with the user's account, and a network management server; wherein the client access terminal is connected to the network management server through the network, the The client access terminal can be a personal computer, a mobile phone, or an ATM terminal for transactions with a...
