Embodiment Construction
[0029] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0030] Such as figure 1 As shown, the present invention provides an electronic security device, including a main station computer and an electronic lock with a unique serial number, the electronic lock is installed on the user equipment, and the main station computer includes:
[0031] The first controller obtains the unique serial number of the electronic lock, automatically generates a random number, and encrypts the unique serial number and the random number to generate the unique key of the electronic lock, and composes the random number, the number of times of unlocking and the verification code into plaintext information , and use the unique key to encr...

The invention provides an electronic security device. The electronic security device comprises a main station computer and an electronic lock with a unique serial number, wherein the electronic lock is mounted on user equipment; the main station computer comprises a first controller. A control method of the electronic security device comprises the following steps: obtaining the unique serial number of the electronic lock, automatically generating a random number, carrying out encryption operation on the unique serial number and the random number to generate a unique secret key of the electronic lock, forming plain-text information by using the random number, unlocking times and check codes, and carrying out encryption operation on the plain-text information by using the unique secret key to generate ciphertext information. Through the electronic security device and the control method thereof, the secret key generated by using the unique serial number of the electronic lock and the random number is unique and cannot be broken easily; the ciphertext information loses efficacy after the ciphertext information is sued for one time; even if the ciphertext information is intercepted, the lock cannot be opened and closed, thereby eliminating the safety concerns; accuracy of the deciphered plain-text information is checked; the lock cannot be opened by wrong plain-text information, thereby guaranteeing the reliability.
Description
technical field [0001] The invention relates to the field of electronic lock control, in particular to an electronic security device and a control method thereof. Background technique [0002] At present, there are two ways to open the electronic lock: password input and wireless control, and the wireless control of the electronic lock mainly includes the radio frequency card swiping type and the wireless key remote control type. When opening and closing the lock, the radio frequency card or wireless key sends the password and operation information to the electronic lock. After the electronic lock verifies that the password is correct, the corresponding opening and closing operation is performed. During this process, passwords and operating information are easily intercepted. After being intercepted, the electronic lock can be opened and closed maliciously by others, causing potential safety hazards. Contents of the invention [0003] The technical problem to be solved by...
