技术领域technical field

背景技术Background technique
无线电子钥匙是一种通过发射无线信号作为开锁密钥,实现开启汽车、家门以及保险柜等的装置。A wireless electronic key is a device that uses wireless signals as an unlocking key to unlock cars, doors, and safes.
在现有的电子钥匙和电子锁装置中,电子钥匙将携带开锁密码的信号通过无线发射电路发射给电子锁装置,电子锁在接收到开锁密码后,通常会对接收到的开锁密码进行验证,判断该用户是否合法,如果合法,则控制电子锁开关开启,否则拒绝开锁。In the existing electronic key and electronic lock device, the electronic key transmits the signal carrying the unlock password to the electronic lock device through the wireless transmission circuit, and the electronic lock usually verifies the received unlock password after receiving the unlock password.

然而,由于电子钥匙与电子锁是分离部件,在用户利用电子钥匙开启电子锁的过程中,携带开锁密码的无线信号必须通过无线传输路径到达电子锁,无线传输路径是一种开放的传输环境,因此在用户的开锁密码的无线信号传输的过程中,可以被任何其他非法用户所窃取记录,一旦非法用户窃取到开锁密码,则会很容易地通过电子设备复制出所窃取用户的开锁密码信号,从而进一步开启该用户的电子锁,实现其行窃的目的,最终使电子锁的合法用户遭受严重损失。However, since the electronic key and the electronic lock are separate components, when the user uses the electronic key to open the electronic lock, the wireless signal carrying the unlock code must reach the electronic lock through the wireless transmission path, which is an open transmission environment. Therefore, in the process of wireless signal transmission of the user's unlock password, the record can be stolen by any other illegal user. Once the illegal user steals the unlock password, it will be easy to copy the stolen user's unlock password signal through electronic equipment, thereby The user's electronic lock is further opened to realize its purpose of stealing, and finally the legitimate user of the electronic lock suffers serious losses.

It can be seen from the above process that the information transmitted through the wireless environment includes random sequences and encrypted random sequences. For random sequences, because they are randomly generated, they are different every time. Therefore, even if they are stolen and recorded by others, It is also difficult to open the user's electronic lock, and for the encrypted random sequence, others can only illegally unlock the lock by deciphering the encrypted random sequence and knowing the decryption algorithm, which is very difficult for the existing encryption system , the probability of success is very small. Therefore, the safety of the electronic lock system can be improved to a great extent through the present invention.
