Key production module, produces the key for encryption information；
Information security module, receives the solicited message of radio receiving transmitting module forwarding and is decrypted, by the solicited message after deciphering
It is forwarded to communication module, receive the control instruction of communication module forwarding and be encrypted, the control instruction after encryption is forwarded to
Radio receiving transmitting module；
Communication module, the solicited message that received information safety module sends simultaneously is forwarded to stm machine main control module, receives stm owner
The control control instruction that issues of module is simultaneously forwarded to information security module.
A kind of near field communication device for stm machine of the present invention, radio receiving transmitting module broadcast key generates
The public key that module sends, receives the request through public key encryption for the nfc equipment, and information security module is sent using key production module
Private key pair request is decrypted, and forwards requests to stm machine main control module by communication module and receives the instruction that it issues, information
Security module occurs the key that module sends that the instruction issuing is encrypted using key, after radio receiving transmitting module will be encrypted
Instruction sends to cnf equipment, and whole wireless communication informations all using cipher-text information, ensure the peace of radio communication by two-way encryption
Entirely, there is provided a kind of wireless notification device with high Information Security being applied to stm machine.
Brief description
Fig. 1 is a kind of system block diagram of the near field communication device for stm machine.
Specific embodiment
As shown in figure 1, a kind of near field communication device for stm machine, comprising: radio receiving transmitting module, receive close
Public key that key generation module sends simultaneously broadcasts public key, receives the solicited message that nfc equipment sends and simultaneously solicited message is forwarded to letter
Breath security module, the control instruction of received information safety module forwards simultaneously forwards control instruction to the nfc equipment being attached thereto；Close
Key generation module, produces the key for encryption information；Information security module, receives the solicited message that radio receiving transmitting module forwards
And be decrypted, the solicited message after deciphering is forwarded to communication module, receives the control instruction of communication module forwarding and carry out
Encryption, the control instruction after encryption is forwarded to radio receiving transmitting module；Communication module, the request that received information safety module sends
Information is simultaneously forwarded to stm machine main control module, and the control instruction that reception stm machine main control module issues simultaneously is forwarded to information security mould
Block.
The key production module described near field communication device that this kind is used for stm machine includes true random number generation
Device, produces the true random number using as key.Due to can produce real random number, each counts existing real random number generator
Probability be equal to, have not regulation, produce module with it as key and can ensure that key is unpredictable, have stronger anti-point
Analysis is anti-to crack ability.
The information security module described near field communication device that this kind is used for stm machine includes, and cryptographic calculation device connects
Receive key and the control instruction that processor forwards, control extension instructs and is forwarded to processor；Cryptographic algorithm device, receiving processor
The key forwarding and request instruction, decoding request instructs and is forwarded to processor；Processor, receives what radio receiving transmitting module sent
Solicited message and the key of key production module transmission, and the solicited message receiving and key forwarding are entered to cryptographic algorithm device
Row deciphering, receives the information after the deciphering of cryptographic algorithm device and forwards it to communication module, receive the control that communication module sends
Instruction and the key of key production module transmission, and the control instruction receiving and key forwarding are solved to cryptographic calculation device
Close, receive the information after the encryption of cryptographic calculation device and forward it to radio receiving transmitting module.This information security module can set to nfc
The standby solicited message deciphering uploading also can be encrypted to the control instruction that stm machine main control module issues, and can achieve two-way ciphertext
Communication is it is ensured that information security.
The near field communication device that this kind is used for stm machine also includes memory module, and storage key production module sends
Key, and record communication module forwarding control instruction.This memory module keeps issuing of control instruction to record to check
Instruction issues lovers, and holding key cannot be to the information using corresponding public key encryption to prevent private key under fortuitous event from losing simultaneously
