Dynamic authentication method for intelligent lock control system of Bluetooth mobile phone

Abstract

The invention discloses a dynamic authentication method for an intelligent lock control system of a Bluetooth mobile phone. The method comprises the following steps: S1, establishing connection; S2, transmitting registration information comprising a user-defined password and a Bluetooth mobile phone identification code; S3, generating a dynamic password by a Bluetooth lock control terminal, and forming a to-be-verified password through the dynamic password, the user-defined password and the Bluetooth mobile phone identification code; S4, transmitting the dynamic password to the Bluetooth mobile phone; S5, packaging the received dynamic password and the user-defined password and the Bluetooth mobile phone identification code transmitted in the S2 into an unlocking password by using the Bluetooth mobile phone; S6, transmitting the unlocking password to the Bluetooth lock control terminal; S7, receiving the unlocking password and verifying with the to-be-verified password by virtue of the Bluetooth lock control terminal; and S8, feeding back the verification result, if the verification is successful, executing the unlocking operation, and generating a new dynamic password, otherwise outputting the prompt information or alarm information. The method has the effects that the password is high in complexity and high in dynamic property, and the condition that technical unlocking is performed by utilizing electromagnetic wave copy can be effectively avoided.

Description

technical field

[0001] The invention relates to electronic control technology, in particular to a dynamic authentication method for a bluetooth mobile phone intelligent lock control system. Background technique

[0002] With the popularization of smart phones, there are more and more applications for smart unlocking or smart startup using mobile phone bluetooth communication. A kind of mobile phone car electronic key and unlocking method and car electronic lock and so on.

[0003] However, in existing applications, the password set between the smart phone and the Bluetooth lock control terminal is too simple, and most of the technical solutions simply use the unique physical address of the mobile phone Bluetooth as the password carrier, or set it artificially. A cipher segment is used as the cipher carrier. When it needs to be unlocked, as long as the mobile phone application software sends the unique physical address of the mobile phone or a few preset passwords, the Bluet...
