Chip is connect with the single-chip microcontroller, and the single-chip microcontroller is connect with the industrial control host, the industrial control host pass through with it is described controllable
Switch is connected with the key modules.
The controllable switch uses signal relay.
The purpose of the present invention also provides a kind of control method of financial self-service equipment communication security control system, including following
Step: after booting, safety control module generates encrypted random number by encryption chip, is sent to industrial control host, this time adds
The 1st group of public key of secret emissary；After industrial control host is decrypted with the 1st group of private key, by the 2nd group of public key encryption of data, by encrypted data
Return to safety control module；Safety control module is decrypted with the 2nd group of private key, if data are correct after decryption, by crucial mould
The communication line of block is connected；If error in data or the data for not receiving return within a specified time, key modules
Communication line is cut off.
The present invention controls the communication line of key modules, works as industrial personal computer by being equipped with this module in key modules

Return to safety control module；Safety control module is decrypted with the 2nd group of private key, if data are correct after decryption, by crucial mould
The communication line of block is connected；If error in data or the data for not receiving return within a specified time, key modules
Communication line is cut off.
The present invention controls the communication line of key modules, works as industrial personal computer by being equipped with this module in key modules
After security module normal communication, key modules just can be with normal communication.
The communication of industrial control host and security module of the invention is encryption, using rivest, shamir, adelman, security module
It can produce random number, communication data has no rule.
Compared with prior art, the present invention improves the safety of key modules, and key modules must be with specified host
It could communicate, could work normally.When using other illegal hosts, key modules will be inoperable.
The above is only a preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
