Problems solved by technology

However, the surrounding device list displayed on the man-machine interface is all Bluetooth device addresses, and the user cannot clearly identify the object to be connected according to these Bluetooth device addresses. Especially in the business field, there are multiple mobile devices with Bluetooth modules around the user. The phenomenon of telephony is very common. When a user intends to use Bluetooth technology to send data to a specific mobile phone, he may search for multiple mobile phones with Bluetooth modules around him. These mobile phones are all displayed in the Bluetooth In the device list, it is difficult for users to identify the corresponding mobile phones based on the addresses of these Bluetooth devices, which makes it difficult for users to make correct choices

Embodiment Construction

[0014] see figure 1 with figure 2 As shown, device A and device B are respectively mobile phones with Bluetooth modules. When device A and device B turn on the Bluetooth function, device A sends data transmission notification information to device B through a secure channel, the secure channel is a data transmission service of the wireless communication system, including SMS service, MMS service or WAP service, The data transmission notification information includes an authentication protocol identifier, a local Bluetooth device address of device A, a PIN code of device A, and a phone number of device A.

[0015] Authentication Protocol ID

telephone number

Bluetooth device address

PIN code

[0016] Wherein, the authentication protocol identification adopts a non-character code as a byte, such as 0x10, the telephone number is a numeric character represented by ASCII code, the address of the Bluetooth device is a 48-bit binary number, and the PIN ...

Abstract

An attestation connection method for mobile telephone set with bluetooth module, which contains 1, transmitting data transmission information from equipment A to B through safety channel, said data transmission information containing attestation protocol mark, local bluetooth equipment address, PIN code and telephone number of equipment A, 2, equipment B transmitting attestation request to A after receiving data transmission reporting information containing local bluetooth address and telephone number of equipment B, generating a attestation cipher key utilizing PIN code of A, 3, equipment A and B making attestation according to bluetooth protocol after A affirming the request information of B, 4, equipment A and B establishing connection in passing attestation.

Description

【Technical field】 [0001] The invention relates to a method for authenticated connection between devices with bluetooth modules, in particular to a method for authenticated connections between mobile phones with bluetooth modules. 【Background technique】 [0002] Bluetooth technology is an open standard for wireless data and voice communication. It is based on low-cost short-range wireless connection and establishes a special connection for the communication environment between fixed equipment and mobile equipment. The typical process of establishing a connection with Bluetooth technology is: a device searches for surrounding devices; selects the device to be connected among the found devices; authenticates between devices; searches for the Bluetooth service on the device to be connected, and the user selects the service to be used to complete the process. connect. Among them, the authentication method can adopt Bluetooth security mode 3 (link-level security mode), that is, i...
