Abstract

The invention relates to the technical field of security. The embodiment of the invention provides a Bluetooth pairing method supporting identity authentication, a security chip and a Bluetooth module. The Bluetooth pairing method supporting identity authentication is based on a key exchange protocol of an identification cryptographic algorithm, and comprises the following steps: acquiring an identity identifier of an opposite-end Bluetooth module; generating exchange data according to the obtained identity label and the identity label of the Bluetooth module at the home terminal; generating a negotiation key according to the exchange data; confirming that the negotiation key is successfully authenticated; using the negotiation key as a pairing key in the pairing process of the home terminal Bluetooth module and the opposite terminal Bluetooth module, wherein the step of generating the exchange data, the step of generating the negotiation key and the step of authenticating the negotiation key are all based on a key exchange protocol of the identification cryptographic algorithm. According to the embodiment provided by the invention, the security and autonomy in the Bluetooth module pairing process are improved.

Description

Technical field [0001] The present invention relates to the field of security technology, particularly, to a support Bluetooth pairing identity authentication method, a safe and an integrated controller chip Bluetooth module. Background technique [0002] Bluetooth is a work in unlicensed 2.4GHz ISM band short-range wireless personal area networks (WPAN) technology, widely used in all types of personal smart devices can exchange data between fixed devices, mobile devices. [0003] Bluetooth security application scenarios set two distrust of Bluetooth devices in operation by the operator, can quickly and simply establish a connection, the connection channel can prevent man in the middle attacks, prevent air interface packet eavesdropping and tampering. Bluetooth security mechanisms include five different security features, pairing, binding, device authentication, encryption and integrity protection. In the Bluetooth protocol stack, the module is associated with a Bluetooth An Quan...
