Problems solved by technology

The Passkey Entry pairing method of the Bluetooth specification must generate and display a pairing code at one end of the two electronic devices to be paired, and enter the correct pairing code at the other end to complete the pairing. The operation is cumbersome
Moreover, the pairing code is public, and any Bluetooth device can be paired with it. The security is not good, and the ability to resist DOS attacks is weak.

Embodiment approach

[0071] Implemented using one-way hash functions such as SHA-1, MD5, and HMAC, a message digest is obtained as a message authentication code.

[0072] In the specific implementation process, for example: HMAC calculates an example of message authentication code MAC1: MAC1 = HMAC(K1,IN); HMAC is a key-related hash operation, which takes a key and a message as input and generates a message digest as output. K1 is a message authentication key here. In the one-way hash function, the message authentication key is only used to input the parameters involved in the calculation, not as a real key. The final output message authentication code MAC1 is discrete Factor, which can be passed IN as the ID code is an input message.

Abstract

The present invention relates to a Bluetooth pairing code allocation method, system, terminal, server and vehicle-mounted equipment, a Bluetooth pairing code allocation method, which is used in the process of Bluetooth pairing between a first electronic device and a second electronic device, and the first electronic device Both the second electronic device and the second electronic device include a Bluetooth protocol operation module for operating based on the Bluetooth protocol stack, including: obtaining identification data of the second electronic device; calculating the obtained identification data through a preset algorithm to obtain a Bluetooth pairing code; The Bluetooth pairing code is transmitted to the Bluetooth protocol operation module of the first electronic device or the Bluetooth protocol operation module of the second electronic device. The invention realizes that the bluetooth pairing code can verify the identity and can be automatically input, so that the bluetooth pairing can be automatically performed.

Description

technical field [0001] The invention relates to the technical field of Bluetooth pairing, in particular to a Bluetooth pairing code allocation method, system, terminal, server and vehicle-mounted equipment. Background technique [0002] The Bluetooth pairing method is generally implemented based on the pairing method of the Bluetooth specification (Passkey Entry). The Passkey Entry pairing method of the Bluetooth specification must generate and display a pairing code at one end of the two electronic devices to be paired, and enter the correct pairing code at the other end to complete the pairing, which is cumbersome to operate. Moreover, the pairing code is public, and any Bluetooth device can be paired with it. The security is not good, and the ability to resist DOS attacks is weak. How to achieve Bluetooth pairing without displaying the pairing code, and for mobile terminal users without manually clicking to confirm the pairing and inputting the pairing code to realize au...
