The invention discloses a wireless safety computer lock. The wireless safety computer lock comprises a computer lock and a key which are matched with each other. The computer lock comprises a universal series bus (USB) interface, a microprocessor, a wireless radio frequency transceiving module and a buzzer used for giving an alarm, wherein the USB interface is connected with a computer. The key comprises a USB interface, a microprocessor, a wireless radio frequency transceiving module, a power supply management chip and a chargeable lithium battery, wherein the lithium battery is charged through the USB interface and the power supply management chip; safe radio frequency communication of a frame transmission protocol encrypted on the basis of an advanced encryption standard (AES) is realized between the computer lock and the key; and the microprocessors of the computer lock and the key comprise a storage area respectively, wherein each storage area stores a unique corresponding identification number. The invention also discloses a using method for the wireless safety computer lock. Due to the adoption of the AES encryption and the wireless radio frequency transceiving modules, reliable and safe short-range wireless communication can be realized by the wireless safety computer lock.
Description
technical field [0001] The invention relates to a device applied to computer security, in particular to a wireless security computer lock and a using method thereof. Background technique [0002] With the popularization of computers, users have put forward higher requirements for the confidentiality and anti-peeping of data and information in computers. [0003] In order to overcome the inconvenience of manually locking and unlocking the screen protection function of the computer, users can use the computer lock to protect the privacy of the computer. At present, known wireless computer locks include an interface circuit, a wireless transmitter, and a wireless receiver. Through the USB interface, when the user leaves the computer, the computer is automatically locked; when the user returns to the computer, the computer is automatically unlocked. However, such a computer lock has huge hidden dangers in the communication security between the wireless transmitter and the wire...
