Abstract
The utility model discloses a kind of financial self-service equipment communication security control system, which includes industrial control host, communication security control module and key modules, and the communication security control module includes encryption chip, single-chip microcontroller, controllable switch；The controllable switch and encryption chip are connect with the single-chip microcontroller, and the single-chip microcontroller is connect with the industrial control host, and the industrial control host is connected with the controllable switch with the key modules.The utility model controls the communication line of key modules, after industrial personal computer and security module normal communication, key modules just can be with normal communication by being equipped with this module in key modules.
Description
Technical field
The utility model relates to financial self-service equipment technical fields, and in particular to a kind of financial self-service equipment communication security control
System processed.
Background technique
Financial self-service equipment, especially ATM etc. are related to the equipment of cash, and cash and personal information security are particularly significant.Have
Key modules use encrypted transmission mode, but it is most of or use plaintext communication mode.Such as paper money supplying module is related to closing
Other key modules of key information, can be operated using corresponding testing tool under normal circumstances, are in practical applications in this way
Extremely dangerous.If criminal obtains the module, critical data may be read into or can be direct using testing tool
Operation module.
Utility model content
The purpose of this utility model is to be directed to technological deficiency existing in the prior art, and provide a kind of financial self-service equipment
Communication security control system.
It is for technical solution used by realization the purpose of this utility model:
A kind of financial self-service equipment communication security control system, including industrial control host, communication security control module and pass
Key module, the communication security control module include encryption chip, single-chip microcontroller, controllable switch；The controllable switch and encryption
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 utility model controls the communication line of key modules, works as work by being equipped with this module in key modules
After control machine and security module normal communication, key modules just can be with normal communication.
The communication of the industrial control host and security module of the utility model is encryption, using rivest, shamir, adelman, safety
Module can produce random number, and communication data has no rule.
Compared with prior art, the utility model improves the safety of key modules, key modules must with it is specified
Host could communicate, and could work normally.When using other illegal hosts, key modules will be inoperable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of financial self-service equipment communication security control system.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
It is shown in Figure 1, a kind of financial self-service equipment communication security control system, including industrial control host, communication security control
Molding block and key modules, the communication security control module include encryption chip, single-chip microcontroller, controllable switch；It is described can
Control switch and encryption chip are connect with the single-chip microcontroller, and the single-chip microcontroller is connect with the industrial control host, the industrial control host
Through being connected with the controllable switch with the key modules.
Specifically, the single-chip microcontroller of communication control control module uses STM32F series in the utility model, there is speed
Fastly, the features such as ram space is big, resourceful.
The single-chip microcontroller and industrial control host is using inexpensive serial port.Wherein, key modules are cash-out machine
Core, cash-out movement and communication security control module can be mounted in safety cabinet.
Specifically, the controllable switch uses signal relay in the utility model.It is fast with switch speed, reliability
The features such as high.
The control method of the financial self-service equipment communication security control system of the utility model, using as follows:
After booting, safety control module generates encrypted random number by encryption chip, is sent to industrial control host, this time
Encryption uses the 1st group of public key；After industrial control host is decrypted with the 1st group of private key, by the 2nd group of public key encryption of data, by number after encryption
According to returning to safety control module；Safety control module is decrypted with the 2nd group of private key, will be crucial if data are correct after decryption
The communication line of module is connected；If error in data or the data for not receiving return within a specified time, key modules
Communication line be cut off.
The utility model controls the communication line of key modules, works as work by being equipped with this module in key modules
After control machine and security module normal communication, key modules just can be with normal communication.
The communication of the industrial control host and security module of the utility model is encryption, using rivest, shamir, adelman, safety
Module can produce random number, and communication data has no rule.
Compared with prior art, the utility model improves the safety of key modules, key modules must with it is specified
Host could communicate, and could work normally.When using other illegal hosts, key modules will be inoperable.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
