The specific embodiment
The embodiment of present embodiment is described identical with last joint, elaborates below in conjunction with Fig. 1 again.When unblanking, the legal password generator of the key of key A1 is to be stored in legal data of key among the key configuration data memory A6 in advance as calculating parameter, with certain algorithm calculate the legal password of key, by the legal password transmitter of key A2 the legal password of key is sent to lock body again.Afterwards, the key configuration data renovator A8 of key upgraded the legal data of key among the key configuration data memory A6 before lock body is carried out final unlocking action, prepare for unblank next time.Meanwhile, after the legal password receiver of the key of lock body A3 received the legal password of key, the legal password verifier A4 of the key of lock body verified the legal password of key.The foundation of checking, be to be stored in key authentication data among the lock body configuration data memory A7 in advance as calculating parameter, go to check the legal password of key whether correct with certain algorithm, as long as the key authentication data of storing among the lock body configuration data memory A7, be complementary with the legal data of key of storing among the key configuration data memory A6, the legal password verifier A4 of key just thinks that the legal password of the key that receives is correct so, otherwise think that the legal password of key is wrong, stop the program of unblanking.If the checking result of the legal password of key is correct, lock body configuration data renovator A9 will upgrade the key authentication data among the lock body configuration data memory A7 so, get ready for unblank next time, last just by the final unlocking action of unlocking apparatus A5 execution.In the above-mentioned complete process of unblanking, the key authentication data that lock body configuration data renovator A9 is upgraded, the legal data of being upgraded with key configuration data renovator A8 of key, keeping matching relationship, if lock body is not by key unlocking, unblank but cracked by the people, have only lock body to upgrade the key authentication data so, and key does not upgrade the legal data of key synchronously, if therefore after cracking, open the lock with the key again, will not match with the legal data of key of storing among the key configuration data memory A6 because of the key authentication data of storing among the lock body configuration data memory A7, cause and to unblank, once be cracked with regard to provable lock body like this.
Embodiment 2
Present embodiment proposes for improving embodiment 1.In embodiment 1, suppose in key configuration data step of updating a8 shown in Figure 1, perhaps in lock body configuration data step of updating a9, powered-off fault takes place, renewal process can not normally be finished, so just can't guarantee the legal data of key of storing among the key configuration data memory A6, keep matching relationship, cause key not unblank with the key authentication data of storing among the lock body configuration data memory A7.In order to distinguish is that present embodiment has been done improvement on the basis of embodiment 1 because powered-off fault still caused key to unblank owing to lock body once is cracked on earth.Referring to Fig. 2, in the program of unblanking of key, before key configuration data step of updating a8, increased the key marker stores step b1 that makes mistakes, correspondingly in key, increased the key marker stores B1 that makes mistakes, after key storage key configuration data step a6, before lock body carries out final unlocking action, increase the key mark of makeing mistakes and removed step b3, correspondingly in key, increased the key mark remover B3 that makes mistakes; In the program of unblanking of lock body, before lock body configuration data step of updating a9, increased the lock body marker stores step b2 that makes mistakes, correspondingly in lock body, increased the lock body mark memory B2 that makes mistakes, after lock body storage lock body configuration data step a7, before lock body carries out final unlocking action, increased the lock body mark of makeing mistakes and removed step b4, correspondingly in lock body, increased the lock body mark of makeing mistakes and removed B4.After so improving, if in key configuration data step of updating a8, perhaps in lock body configuration data step of updating a9, powered-off fault takes place causes renewal process normally not finish, so in key is made mistakes mark memory B1, perhaps will remain with the mark of makeing mistakes at the lock body mark memory B2 that makes mistakes, so just can identify is can not unblank owing to powered-off fault causes key, but not lock body was once cracked by the people.
Present embodiment also can change the program of unblanking of key into shown in Figure 3.The distinctive points of Fig. 3 and Fig. 2 only is the key marker stores step b1 that makes mistakes has been moved on to before the legal password forwarding step of key, so also can play same effect.Other flow process among Fig. 3 is identical with Fig. 2.
Need to prove, though the situation of powered-off fault may take place in the store and clear step of the mark of makeing mistakes equally, but mark only is to use as a mark owing to make mistakes, can only represent with single byte, even only use one " 0 " or " 1 " in the byte to represent, therefore its store and clear speed is very fast, and the probability that powered-off fault takes place in its store and clear process is almost nil.
Embodiment 3
Though embodiment 2 has had further improvement than embodiment 1, but still there are some leaks.Suppose that an electronic lock user who grasps advanced techniques wants to swindle producer, this user implements swindle possibly so so: the lock body that produces a vacation earlier, use very key operated this false lock body again, make complete program of unblanking of true key experience, so according to embodiment 2 described key unlocking programs, the legal data of the key of true key will change at step a8, and the key mark of makeing mistakes also can be eliminated in step b3, and real lock body does not participate in opening process, the key authentication data that are true lock body do not change the mark nor existence makes mistakes, when whether producer's checking lock body once was cracked, true key can't be opened true lock body, and true key and the true lock body mark of all not makeing mistakes, therefore producer will be cheated.In addition, this user also might implement swindle like this: when with very key operated false lock body the time, do not allow true key experience the complete program of unblanking, but sending the legal password of key, the key of only taking seriously grants the leave behind the lock body, just stop true key to carry out remaining step with power down or other method, the legal data of key of true key are not changed and do not store the key mark of makeing mistakes, and then with one imitated false key, the legal password of intercepting and capturing of key is sent to true lock body, make complete program of unblanking of true lock body experience, so the key authentication data of true lock body will change at step a9, no longer with the legal Data Matching of the key of true key, and the lock body of the true lock body mark of makeing mistakes also can be removed in step b4, therefore when whether producer's checking lock body once was cracked, true key can't be opened true lock body, and true key and the true lock body mark of all not makeing mistakes, and therefore producer also can be cheated.For stopping this situation, present embodiment makes improvements on the basis of embodiment 2 again.Referring to Fig. 4, in lock body, increased lock body legal password generator C1 and the legal password transmitter of lock body C3, increased sealed method data in the lock body configuration data of in lock body configuration data memory A7, storing.Sealed method data are that the legal password generator of lock body C1 is rely and produced the calculating parameter of the legal password of lock body, that is to say in step c1, the legal password generator of lock body C1 produces the legal password of lock body to be stored in sealed method data among the lock body configuration data memory A7 in advance as calculating parameter with certain algorithm.Correspondingly, in key, increase lock body legal password receiver C4 and the legal password verifier C5 of lock body, increased the lock verification msg in the key configuration data of in key configuration data memory A6, storing.Whether correct the lock verification msg be the legal password verifier C5 of the lock body legal password of lock body that receives of checking the calculating parameter of relying, that is to say that the legal password verifier C5 of lock body is to be stored in lock verification msg among the key configuration data memory A6 in advance as calculating parameter, go to check the legal password of lock body whether correct with certain algorithm, as long as the sealed method data of storing among lock verification msg of storing among the key configuration data memory A6 and the lock body configuration data memory A7 are complementary, the legal password verifier C5 of lock body will think that the legal password of the lock body that receives is correct, otherwise think that the legal password of lock body is wrong, stop the program of unblanking of key.Present embodiment is the marker stores step b1 that makes mistakes of the key in the special provision key unlocking program also, must be before the legal password forwarding step of key a2 finishes; Lock body lock body in the program marker stores step b2 that makes mistakes that unblanks must be before the legal password forwarding step of lock body c3 finishes.Only explain below with regard to the step that is different from previous embodiment among Fig. 4:
The execution in step b2 of lock body elder generation, the storage lock body mark of makeing mistakes in lock body is made mistakes mark memory B2, again by the legal password generator of lock body C1 execution in step c1, to be stored in sealed method data among the lock body configuration data memory A7 in advance, produce the legal password of lock body with certain algorithm as calculating parameter; Before lock body configuration data step of updating a9,, the legal password of lock body is sent to key by the legal password transmitter of lock body C3 execution in step c3; In key, after the legal password receiver of the lock body of key C4 receives the legal password of lock body, by the legal password verifier C5 execution in step of lock body c5, whether the legal password of checking lock body is correct, the foundation of checking, be to be stored in lock verification msg among the key configuration data memory A6 in advance as calculating parameter, go to check the legal password of lock body whether correct with certain algorithm, as long as the sealed method data of storing among lock verification msg of storing among the key configuration data memory A6 and the lock body configuration data memory A7 are complementary, the legal password verifier C5 of lock body will think that the legal password of the lock body that receives is correct, otherwise think that the legal password of lock body is wrong, stop the program of unblanking of key, if the checking result of the legal password of lock body is correct, then continue execution in step b1.So far finish the checking of key to lock body, later step and previous embodiments, key is execution in step a8, a6, b3 successively, and lock body is execution in step a3, a4, a9, a7, b4, a5 successively.What specify is that in key configuration data step of updating a8, the key configuration data that is upgraded comprises the lock verification msg that present embodiment increases; In lock body configuration data step of updating a9, the lock body configuration data that is upgraded comprises the sealed method data that present embodiment increases, and the sealed method data maintenance coupling of lock verification msg of upgrading and renewal, gets ready for unblank next time.From the step process of present embodiment as can be known, present embodiment had been stored the key mark of makeing mistakes earlier before the legal password forwarding step of the key of key a2 finishes, guaranteed the integrality of key from the legal password forwarding step of key a2 to key configuration data step of updating a8; Key is also verified lock body in addition, and in the process of at every turn unblanking, the sealed method data that are used to produce the legal password of lock body of storing among the lock body configuration data memory A7, and being used to of storing among the key configuration data memory A6 verify the lock verification msg that the legal password of lock body is whether correct, the capital changes, so copy out false lock body that an energy approved by true key and be unusual difficulty, so present embodiment can be stopped the described at the beginning leak of this section.
Whether whether flow process shown in Figure 4 is earlier correct by the legal password of the lock body of key authentication lock body, correct by the legal password of key of lock body checking key again.In fact present embodiment also can adopt flow process shown in Figure 5.Whether whether the distinctive points of Fig. 5 and Fig. 4 only be correct, correct by the legal password of the lock body of key authentication lock body again by the legal password of key of lock body checking key earlier.Particularly, that is first by key execution in step b1, a2 successively, the legal password of key is sent to lock body, lock body is execution in step a3, a4 successively, the legal password of key is verified, if correct, then lock body is made mistakes after the marker stores step b2 having carried out lock body, execution in step c1, c3 send to key with the legal password of lock body, correspondingly again, key execution in step c4, c5, the legal password of lock body is verified if correct, then lock body continues execution in step a9, a7, b4, a5 successively.Other step among Fig. 5 is identical with Fig. 4.
Embodiment 4
Also there is another problem in embodiment 2, if lock body very was cracked, the lock body configuration data of the lock body configuration data memory A7 of lock body storage is inevitable so is updated, if this moment is again with the key operated lock that once was cracked, certainly just can't unblank, but the key mark memory B1 that makes mistakes of key will remain with the key mark of makeing mistakes this moment, so producer will deny in view of the above that lock body once was cracked, and this is irrational.For addressing this problem, present embodiment has increased following steps:
D1, key produced the synchronous legal password of synchronous legal password before the storage key is made mistakes mark. and produce step, correspondingly in key, increased synchronous legal password generator D1;
D2, the key configuration data of being stored in key configuration data storing step also comprise synchronous legal data, and described synchronous legal data are the calculating parameters that produce the synchronous legal password of generation of relying in the step at the synchronous legal password of key.Correspondingly, the key configuration data of storing in key configuration data memory A6 comprises synchronous legal data;
D3, key sent to the synchronous legal password forwarding step of lock body with synchronous legal password before the storage key is made mistakes mark, correspondingly increased synchronous legal password transmitter D3 in key;
D4, lock body receive the synchronous legal password receiving step of synchronous legal password, have correspondingly increased synchronous legal password receiver D4 in lock body;
D5, lock body are before the storage lock body is made mistakes mark, verify whether synchronous legal password is correct, if correctly then continue to move the program of unblanking, the synchronous legal password authentification step of program has correspondingly increased synchronous legal password verifier D5 in lock body if incorrect then termination operation is unblanked;
D6, the lock body configuration data of being stored in lock body configuration data storing step a7 also comprise synchronous verification msg, whether correct described synchronous verification msg be the synchronous legal password that receives of checking the calculating parameter of relying in the synchronous legal password authentification steps d 5 of lock body, that is the synchronous verification msg in the lock body configuration data and the synchronous legal data in the key configuration data are complementary the different corresponding different synchronous legal data of synchronous verification msg.Correspondingly, the lock body configuration data of being stored in lock body configuration data memory A7 comprises synchronous verification msg.
