Description
Technical field:
The invention belongs to electronic technology field, relate to the technology that adopts password to carry out identification, relate to cipher door lock and key especially.
Background technology
The method of usually carrying out identification can be divided into following two classes:
1. according to geostationary identification authority, for example rely on the mechanical type key of roller seating space identification, rely on electronic key or card, the reusable password etc. of the electromagnetic signal identifications such as resistance or inductance;
2. all change the mode of basis of characterization after each identification, representational is the rolling code recognition technology that is widely used in car alarm.
The major defect of first kind method is that key is easy to duplicate, and the people who holds copy key can the acquisition system trust equally, therefore has potential safety hazard.Particularly on door-locking system, in case losing, key often to change lockset.And for traditional antitheft door with the mechanical type key, the thief can open lock with skeleton key or powerful steel disc.For by pressing the antitheft door of password unlocking, be intended to person agaainst the law also can aside peep steal password.In addition, it is not identify the ability of different keys that these class methods also have a shortcoming, the operating position that therefore is difficult to trace every key.
Though the rolling code technology has increased difficulty for the eavesdropping password, as long as obtain cryptographic algorithm, and the process of unblanking of same key of continuous several times monitoring, just can break a code, calculate rolling code, thereby gain system identification by cheating.
In addition, these two class methods also have some common shortcomings, i.e. the corresponding lock of key.Usually, everyone needs out many locks, therefore, usually is being with many keys on one's body, and not only also there is potential safety hazard in inconvenience.And traditional lock---key system also can't transmit additional private information when identification, be difficult to expanded function, also is difficult to the operating position of each key of record, traces reason when being unfavorable for accident occurring.
Consider these weak points just, the present invention proposes a kind of new personal identification method and device, as key, can guarantee that identity information is not reproducible by dynamic password generating mode and the mobile phone that adopts the operation specific program, possess uniqueness, and password can not the property decoded; And many keys are concentrated on same the mobile phone, make carry, use, the keeping key is all very convenient; By locking the service data logging program, can write down the operating position of every key, both helped the real-time registration of gate control system, also be convenient to trace afterwards; The lock that adopts the antitheft door of describing method of the present invention and device not expose, so the burglar can't make a forcible entry into by modes such as picking locks; In addition, the method that adopts the present invention to describe can also be safely and is transmitted sensitive data easily, therefore can also be widely used in fields such as charge authentication.
