Figure.
Specific embodiment
It is below in conjunction with the accompanying drawings and real to make the purpose of the present invention, content and advantage clearer
Example is applied, specific embodiment of the invention is described in further detail.
The present invention is proposed one kind and is then differentiated password encryption again using dynamic random number
Method.Using dynamic random number is by password encryption and then carries out being mainly for mirror method for distinguishing again
The process of request random number is increased before password authentication.Concrete principle is：
Before discriminating starts, external equipment asks random number firstly the need of to smart card, then utilizes
Random number is encrypted as key to the password data of user input, is finally then forwarded to intelligence
Card, after data are received, the random number before is solved smart card as data key
It is close, password authentication is then carried out again.If both sides use identical random number and AES,
As long as so the password of user input correctly just can be by the password authentication of smart card.Now such as
Fruit attacker has listened to the packet of discrimination process, just cannot be by intelligence using Replay Attack
The password authentication of card, but what the requirement request random number for receiving smart card return was differentiated again
Error reporting.
Fig. 1 is the flow chart of the password authentication method that the present invention prevents Replay Attack, such as Fig. 1 institutes
Show, the smart card operating system password authentication process bag for preventing Replay Attack that this patent is proposed
Include：
S1, smart card operating system are initialized；
S2, external equipment send the order that request differentiates, intelligent clamping to smart card operating system
