Accompanying drawing explanation
Fig. 1 is the binding flow chart of realizing intelligent bracelet and intelligent mobile terminal in the embodiment of the present invention;
Fig. 2 is the identifying procedure figure that realizes intelligent bracelet and intelligent mobile terminal in the embodiment of the present invention.
Embodiment
The present invention is intended to propose a kind of binding and authentication method of realizing intelligent bracelet and intelligent mobile terminal, to realize the secure binding pairing between intelligent bracelet and intelligent mobile and to utilize intelligent bracelet to realize the access control to intelligent mobile terminal.
Below in conjunction with drawings and Examples, the solution of the present invention is further described:
The present invention improves Diffie-Hellman agreement at initialization procedure, joining day stamp authentication is also carried out authentication in conjunction with the IMEI number of bracelet MAC Address and intelligent mobile terminal, and in initialization procedure, we have considered the safety problem of channel, by judgement bracelet Bluetooth signal intensity, rssi limits intelligent mobile terminal and the initialized distance of bracelet, the distance threshold that can be controlled at setting be take interior (can be for example <10 centimetre by threshold value setting), to guarantee channel safety, avoid the problem of man-in-the-middle attack.In addition, also support to use NFC to carry out initialize communications, because the communication distance of NFC is shorter, the man-in-the-middle attack that also can encode in initialization procedure.
Take intelligent mobile terminal as mobile phone, between mobile phone and bracelet, by bluetooth approach, communicate by letter as example, as shown in Figure 1, realize the step of binding between mobile phone and bracelet as follows:
1. mobile phone detects the Bluetooth signal intensity rssi of intelligent bracelet, and relatively the value of rssi and initializing signal intensity threshold values SIT, if rssi is more than or equal to threshold values SIT, continues initialization procedure, enters step 2, on the contrary initialization failure, process ends; The threshold values SIT has here set default value, and this value also can be by user's self-defined setting as required, and for trying one's best of the communication distance control between mobile phone and bracelet is little of to ensure channel safety, what threshold values SIT can be arranged is larger;
2. bracelet generates a random prime number x, calculates X=g xmod p, generates the unique identification code BID of bracelet in conjunction with the MAC Address of bracelet, read the current time T of bracelet simultaneously 0, and by { X, BID, T 0issue mobile phone; Wherein, integer g and prime number p are two disclosed parameters of the overall situation, the primitive root that g is p;
3. mobile phone receives that bracelet is after the information of step 2 transmission, and stab first Check-Out Time, then generates a random prime number y, calculates Y=g ymod p and k 0=X ymod p, the while generates the unique identification code PID of mobile phone terminal in conjunction with the IMEI number of mobile phone, read the time T of current phone 1, and adopt k 0encrypt BID and generate E k0(BID), finally will issue bracelet;
4. bracelet receives that mobile phone is after the message of step 3 transmission, and stab first Check-Out Time, then calculates k 0'=Y xmod p, uses k 0' decipher the message of receiving, obtain adopt again k 0' encrypt BID to generate E k0 '(BID), judgement E ko(BID) whether equal E k0 '(BID), return to result information, if equated, to mobile phone, return to the message of initialization success; Otherwise, return to initialization failed message, process ends;
5. after initialization success, mobile phone terminal is stored { BID, k 0, E k0(BID) }, bracelet storage { E k0(BID) }, realize the binding between bracelet and mobile phone.
In the implementation of above-mentioned initialization binding, we add BID, PID further to judge the other side's identity in existing Diffie-Hellman agreement, and in BID transmitting procedure, adopt AES cryptographic algorithm to be encrypted, and increase fail safe.Simultaneously our also joining day stamp authentication techniques, prevent obstructive attack and Brute Force.
After the initialization binding realizing between mobile phone and bracelet; user, need to access the protected information (privacy information in mobile phone; can mark be set voluntarily by user) time; we can utilize the parameters for authentication of storing in bracelet to authenticate mobile phone, thereby realize convenient, safe access control.
As shown in Figure 2, realize the step authenticating between mobile phone and bracelet as follows:
1. mobile phone detects the Bluetooth signal intensity rssi of bracelet, and relatively the value of rssi and authentication signal intensity threshold values SIT ', if rssi is more than or equal to threshold values SIT ', continues verification process, enters step a, on the contrary authentification failure, process ends; Equally, the threshold values SIT ' here can be by user's self-defined setting as required, for trying one's best that the communication distance between mobile phone and bracelet is controlled little of to ensure channel safety, can be by threshold values SIT ' setting larger;
2. when user accesses the protected information on mobile phone, mobile phone sends authentication request notice { query, N to the bracelet with its binding p, N pit is a random number;
3. bracelet is received after authentication request notice, generates random number N band return to mobile phone
4. mobile phone is received after the message that intelligent bracelet returns in step 3, detects E ki(BID) whether with the equating of mobile phone terminal storage, if detect errorless, authentication success, the protected information in mobile phone terminal permission user access terminal;
5. mobile phone upgrades K ifor K i+1, K i+1for random number, upgrade N pfor Np ', calculate { E ki+1(BID) }, m = H ( E ki + 1 ( BID ) &CirclePlus; Np &prime; | | Nb ) , e = E ki ( BID ) &CirclePlus; E ki + 1 ( BID ) , Again m and e are sent to intelligent bracelet;
6. bracelet, after receiving the message that mobile phone sends in step 5, detects E ki(BID), and if store E in bracelet ki(BID) consistent, upgrade { E ki(BID) } be { E ki+1(BID) }.
In above-mentioned certificate scheme, " ⊕ " is XOR, and " || " is bound symbol, and " H " is hash function, and " E " is encryption function.
Owing to relating to XOR, cryptographic algorithm, hash algorithm and random number generating run in improved agreement, by these operations, hide true BID, guarantee data transmission security, prevented the common attacks such as eavesdropping, information playback, data forgery, and each authentication all can be upgraded E ki(BID), also increased fail safe.
