Intelligent lock data encrypted transmission method and leasing equipment applying same

Abstract

The invention relates to an intelligent lock data encrypted transmission method and leasing equipment applying the same and belongs to the technical field of intelligent locksets. A complicated encryption algorithm is very difficult to realize through a calculation capability of an existing intelligent lock microcontroller and has certain safety risks. An initial value is solved by utilizing current time of a server side, a key (KEY) of data can be changed at any time and the difficulty of cracking the encrypted data is enhanced; meanwhile, two initial values are solved by the intelligent lockset according to local time and the encrypted data is decrypted; effective data is determined through comparing decrypted verification codes; the scheme is detailed and feasible; a locket key does notneed to be distributed; the encryption and decryption efficiency of the data can be extremely improved; the method is easily realized on the microcontroller and has the advantages of small occupationof microcontroller RAM (Random Access Memory) and FLASH resources, rapid calculation speed and the like, and the safety of the intelligent lock in the aspect of communication is improved.

Description

technical field [0001] The invention relates to an intelligent lock data encryption transmission method and rental equipment using the same, belonging to the technical field of intelligent locks. Background technique [0002] With the development of society, traditional mechanical locks cannot meet the current growing demand due to safety and convenience, and smart locks have gradually become popular. Smart locks can be used without carrying them, which greatly increases convenience. Smart locks generally need to be powered by batteries. In order to reduce the frequency of battery replacement, it is necessary to reduce the power consumption of smart locks. Therefore, most of the current smart lock control cores are microcontrollers with low power consumption. [0003] In the process of opening the door with a conventional fingerprint, password, ID card or IC card, the smart lock can effectively guarantee security, but in the case of wireless communication or access to the In...

Problems solved by technology

[0003] In the process of opening the door with a conventional fingerprint, password, ID card or IC card, the smart lock can effectively guarantee security, but in the case of wireless communication or access to the Internet, the computing power of the microcontroller is difficult to implement complex encryption algorithms. Even most of the smart lock data on the market is almost transparent or unencrypted, which greatly increases the probability of cracking, and even cracking one of the locks will cause all locks of the same type to be cracked, which increases the security risk
