Be made up of bluetooth communication module 3, safety chip 4 and electric energy module of meter control 5, by bluetooth communication module 3 establish intelligent terminal 1 with
The communication of electric energy module of meter control 5, described safety chip 3 are responsible for the CCKS algorithms in two-way authentication and data encryption process
Computing, described electric energy module of meter control 5 are responsible for carrying out communication with ammeter 6 by master meter control protocol and interacting；Using
CCKS carries out two-way authentication and the encryption communication of electric energy module of meter control and intelligent terminal, makes electric energy module of meter control 5 and user
Intelligent terminal 1 by bluetooth communication, pass through exchange id, by interacting at least once, certification both sides with electric energy module of meter control 5
Identity it is whether legal, that is, it is whole to complete the certification electric energy module of meter control 5 of intelligent terminal 1 and the authentication intelligent of electric energy module of meter control 5
The two-way authentication at end 1, and the exchange of complete process key is consulted simultaneously, wherein, during intelligent terminal 1 consults described exchange
Process key, using rivest, shamir, adelman encrypted instruction and it is sent to electric energy meter control module 5 and gives certification, if certification is led to
Cross, carry out subsequent operation, including directly establish safety communication, and then provide and supplement sale of electricity, parameter renewal, the work(of information inquiry with money
Energy；If the authentification failure of any one party is in abnormal ending.
Including：The smart mobile phone of intelligent terminal 1, such as user；Intelligent electric meter control module 2, the module is by bluetooth communication
Module 3, safety chip 4 and electric energy module of meter control 5 form.Wherein, bluetooth communication module 3 is responsible for building between intelligent terminal 1
Vertical bluetooth communication；Safety chip 4 is responsible for the CCKS algorithm computings in two-way authentication and data encryption process, and safety chip can be adopted
Realized with general-purpose chip, such as ARM Cortex family chips etc.；Electric energy module of meter control 5, which is responsible for controlling by master meter, assists
View such as 645 stipulations carry out communication with ammeter 6 and interacted.
As shown in Fig. 2 intelligent terminals and the interaction flow schematic diagram of intelligent electric meter control module, comprise the following steps that：
Step 1 establishes bluetooth communication.Intelligent terminal passes through the Bluetooth protocol of standard, the controllable intelligent electric meter of automatic identification
Control module, and establish bluetooth communication.
Step 2 two-way authentication domain key exchanges.Intelligent terminal, by exchange id, passes through one with intelligent electric meter control module
Whether the identity that both sides just can be certified in secondary interaction is legal, completes intelligent terminal authentication intelligent ammeter control module and intelligent electric meter
The two-way authentication of control module authentication intelligent terminal, and the exchange of complete process key is consulted simultaneously.Enter if certification if
Row subsequent operation, causes operation exception to terminate if the authentification failure of any one party.
Step 3 intelligent terminal utilizes the process key that previous step is consulted, and using symmetric encipherment algorithm encrypted instruction and sends
Give intelligent electric meter control module.
After step 4 intelligent electric meter control module receives instruction, decrypt and parse, send instructions to ammeter and be controlled.
If any subsequent process, then repeat step 3, otherwise terminate the process.
The process that two-way authentication and key in above-mentioned steps 2 exchange is as shown in figure 3, specifically：
1st, intelligent terminal generates a 8 byte random number Rs 1, obtains the CCKS mark ID1 of oneself, and calculates the signature to R1
C1 S1, intelligent electric meter control module is sent to by certification and key exchange instruction, the call parameter of instruction is ID1, R1, C1,
S1。
2nd, after intelligent electric meter control module receives certification and key exchange instruction, blacklist is first passed through（Or white list）With
（Or）ID rule certifications ID1 legitimacy, the public key PUB1 for being calculated by ID1 and obtaining intelligent terminal is passed through after, to signature value C1
S1 carries out sign test, and sign test can carry out following step by then illustrating that intelligent terminal is legal；Intelligent electric meter control module generation with
Machine number R2, process key K is obtained by R1 and R2 XOR, then intelligent electric meter control module obtains the CCKS marks of oneself
ID2, and R2 is encrypted using public key PUB1 and obtains ENC2, then ENC2 is signed and obtains C2 S2, after completing above-mentioned calculating, intelligence
Ammeter control module terminates certification and key exchange instruction processing procedure, and returns to following data to intelligent terminal：ID2、ENC2、
C2, S2 and answer code.
3rd, after intelligent terminal receives return, blacklist is first passed through（Or white list）With（Or）ID rule certifications ID2's is legal
Property, the public key PUB2 for being calculated by ID2 and obtaining intelligent terminal is passed through after；Intelligent terminal carries out sign test using PUB2 to C2 S2, tests
Label can carry out following processes by then illustrating that intelligent electric meter control module is legal；The private key decryption of intelligent terminal private key oneself
ENC2, random number R 2 is obtained, process key K is obtained by R1 and R2 XOR.Since then, intelligent terminal and intelligent electric meter control mould
Block completes the certification of both sides, and obtains process key K, can carry out follow-up encryption communication.
It can be seen that from above-mentioned steps in the present invention, in whole authentication procedures, mobile terminal and intelligent electric meter
Between only need to carry out external authentication and internal authentication once to interact, contrast existing certification and key exchange process be greatly simple
Change.All by both can verify that the identity of both sides is legal, exchanging again and having consulted process key, whole process is safe and reliable, and
It is convenient and swift.
It can respectively be encrypted/decrypt using different subdomain public private key pairs and signature/sign test, it is further provided safety
Property；
When needing more fine-grained control of authority, whether different control instructions have permission execution, can be by using different sons
Domain public private key pair is carried out respectively.Such as：Only it is authenticated using subdomain 1 after being exchanged with key, can just performs control instruction
" ammeter clearing "；Only it is authenticated using subdomain 2 after being exchanged with key, can just performs control instruction " breaker tripping and closing " etc..Can
Further increase flexibility and the security of intelligent electric meter control module.
Above by the embodiment for describing each process respectively, the present invention, the technology of this area is described in detail
Personnel will be understood that.In the scope for not departing from essence of the invention, it can make an amendment and deform, for example the stripping of part of module makes
With with by system embedment in other application system.
