Description
Technical field
The present invention relates to method for unlocking and lockset, relate in particular to electronic code unlocking method and electronic coded lock device.
Background technology
The restriction that the technical development of lock and popularization and application mainly are subjected to three factors: safety, convenience and cost performance.Cost performance constantly changes along with the improvement of production technology.How inciting somebody to action safety and convenient two big factor combinations to greatest extent, is the difficult problem that entire society faces jointly.
Since computer comes out, taken leave of the situation that mechanical lock rules all the land, formed the situation of mechanical lock, electronic password lock and mechanical-electronic puzzle lock coexistence, they are bringing into play each self-applying because of characteristics separately in different field.But lock all exists technological deficiency separately at present, well combination safety and this two big factor that makes things convenient for.The shortcoming of mechanical lock is that key duplicates easily and is difficult for being found, and lock is vulnerable to outside destroy and loses protective effect.Existing coded lock has a lot of types, such as dial-type coded lock, push-button puzzle lock, fixed password formula coded lock and dynamic password formula coded lock.The shortcoming of dial-type coded lock and push-button puzzle lock is to leak password when unblanking easily, also needs artificial memory's password to increase inconvenience.Fixed coded lock and dynamic password formula coded lock are that present safety is higher, and its shortcoming is that password can be replicated and Brute Force.Therefore, it is complete and be convenient to electronic password lock all over the body to be badly in need of Jian.
Summary of the invention
The present invention is directed to the password that exists in the prior art and easily be replicated deficiency with Brute Force, provide a kind of and utilized a chain of checking of multiple information and password to unblank, avoid to greatest extent key be replicated with password by the electronic code unlocking method and the electronic coded lock device of each side potential safety hazards such as Brute Force.
