Electronic lock safety system and key distribution method thereof

Abstract

The invention discloses an electronic lock safety system and a key distribution method thereof. A electronic lock terminal and a mobile communication terminal generate a temporary communication key according to temporary data, and the electronic lock terminal encrypts the ID of an electronic lock security chip and the ID of an electronic lock by using a temporary communication key and a public keyof a key management center, and decrypts an encrypted private key of the mobile communication terminal to obtain a first component of the private key; and the mobile communication terminal encrypts the number of the mobile communication terminal by using the temporary communication key, sends a request for applying for the certificate and the private key of the mobile communication terminal to the electronic lock terminal, realizes forwarding between the electronic lock terminal and the key management center terminal, obtains, encrypts and stores a second component of the private key of the mobile communication terminal, and verifies the certificate of the key management center and the certificate of the mobile communication terminal. The key management center terminal generates a certificate and a private key corresponding to the number of the mobile communication end by using the private key of the key management center based on a public key of the electronic lock security chip, andsends the certificate and the encrypted private key of the mobile communication terminal to the mobile communication terminal after encryption. Secure issuing of the certificate and the private key of the mobile terminal is realized, and the security of the key is ensured.

Description

technical field [0001] The invention relates to the technical field of electronic locks, in particular to an electronic lock security system and a key distribution method thereof. Background technique [0002] At present, in the field of security technology prevention, electronic locks have overcome the shortcomings of poor security performance of mechanical combination locks and become the main force in the market. The use modes of electronic locks mainly include electronic locks not connected to the Internet and electronic locks connected to the Internet. The electronic lock is not connected to the network mode, mainly for ordinary residential users. The mobile communication terminal installs the unlock APP, and the electronic lock terminal and the mobile communication terminal establish a connection through Bluetooth. The mobile communication terminal communicates with the business server based on Bluetooth. Bind with the mobile communication terminal APP and distribute t...

Problems solved by technology

[0003] The unlocking function of the mobile communication APP is based on near-field communication. Although it provides users with high convenience, it also faces two security threats. Due to the openness of the wireless channel, the unlocking information is stolen, copied, counterfeited, etc.; the second is that after the mobile communication device is lost, the unlocking information stored in the mobile communication device cannot be destroyed in time, which may pose a serious threat to the personal and property safety of the user

At present, public algorithms such as AES and RSA are used between the electronic lock and the mobile communication terminal APP to realize simple identity authentication and encryption functions, but the security capability is weak, there is no anti-tampering and anti-replay function, and the electronic lock and mobile communication equipment The saved unlock password is not protected and vulnerable to attack
