Bluetooth-based unlocking method, system and hand-held terminal and Bluetooth-based electronic lock

Abstract

The invention provides a Bluetooth-based unlocking method, system and hand-held terminal and a Bluetooth-based electronic lock. The method comprises steps as follows: the hand-held terminal with a Bluetooth function is bound with the electronic lock in a Bluetooth communication manner, and an unlocking password of the electronic lock is generated; when the electronic lock is unlocked, the hand-held terminal sends an unlocking request and sends a hash value acquired through hash calculation to the electronic lock after a group of random numbers fed back from the electronic lock are received and a combination of user ID (identification), the unlocking password and the random numbers is subjected to hash calculation; the electronic lock matches the hash value acquired after hash calculation of the combination of the user ID, the unlocking password and the random numbers with a hash value received by the hand-held terminal, and the electronic lock is unlocked after matching succeeds. Interactive authentication is performed in a hash encryption manner, monitoring by a third party can be prevented, the condition of secret key disclosure is avoided, the unlocking speed is high, and the safety of the electronic lock is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to the technical field of start-up control of mobile terminals, and specifically relates to a bluetooth-based unlocking method, system, handheld terminal and electronic lock. Background technique [0002] As a new short-distance wireless communication technology standard, Bluetooth has broad application prospects and is receiving widespread attention from all walks of life around the world. The emerging bluetooth technology has entered the development period from the embryonic period, although compared with other short-distance wireless technologies (such as: IEEE802.11b, HomeRF, IrDA), the advantages of bluetooth technology are still very controversial. However, it is still an inevitable trend for mature Bluetooth products to enter the market. Bluetooth technology has the following characteristics: support users to perform wireless data exchange and file synchroni...
