Description

Pairing method, pairing device, smart terminal and smart card

Technical field

The present invention relates to the field of Bluetooth communication, and in particular, to a pairing method, a pairing device, and an intelligent terminal and a smart card.

Background technique

Bluetooth is one of the most widely used short-range wireless communication technologies. It has been widely used in various electronic devices and operates in the 2.4 to 2.485 GHz ISM (Industrial Scientific Medical) band.

Any wireless communication technology has the possibility of cracking and being monitored. In order to ensure the security and convenience of Bluetooth communication, the two Bluetooth devices complete the first communication authentication in the form of pairing, and the data can be exchanged after the authentication. A binding is formed between the two successful devices, and the subsequent pairing process is not required. However, if the pairing is not paired, the authentication relationship cannot be established between the two devices, and the connection and subsequent operations cannot be performed. Therefore, the pairing ensures the security of the Bluetooth communication to a certain extent. However, since many personal electronic devices do not have a human-machine interface, the PIN code (Personal Identification Number) is fixed or mostly set to the common 0000 or 1234, which makes it easy to be guessed, so this security The guarantee mechanism is relatively easy to crack.

There are currently two pairing mechanisms:

(1) Traditional password pairing: This is the only way to pair Bluetooth version 2.0 with its earlier version. If both parties have input devices, both parties need to input the same PIN code to be successfully paired. But for limited input devices (such as Bluetooth headsets), these devices usually still use a fixed PIN code (such as 0000 or 1234, etc.) as the pairing password.

(2) Secure Simple Matching (SSP): This is required by Bluetooth 2.1 and later versions. The 6-digit random number on the screen can be the same. Compared with the (1) pairing method, the operation is simpler and the security is stronger. However, both Bluetooth devices have a screen and an input device, so the pairing method cannot It is applied to Bluetooth devices that require very high security levels and do not have display screens and input devices.
