A method, device and system for secure pairing

Abstract

The invention discloses a method, a device and a system for safe pairing. The method comprises the following steps: in an untrusted environment, a security device receives a first information sent bya host device, the first information including an information identification code of the host device and a certificate of the host device; the security device generates second information according tothe first information, the second information including an information identification code of the host device, a certificate of the host device and an information identification code of the securitydevice; the security device sends the second information to the server so that the server judges whether the security device and the host device allow pairing or not; the security device receives thethird information sent by the server; the security device sends a fourth message to the host device such that the security device and the host device are paired, the fourth message comprising a certificate of the security device. By the method, the secure pairing of the secure device and the host device in an untrusted environment can be realized, and the security cost can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of mobile computing security, in particular to a method, device and system for secure pairing. Background technique [0002] With the continuous development of electronic technology, more and more mobile devices start to use security devices (such as fingerprint modules) to improve the security of mobile devices. The fingerprint security device is an unlocking device that uses fingerprint data for record verification and avoids additional cumbersome identification processes. [0003] In the prior art, in order to ensure secure pairing between the security device (such as the fingerprint module) and the host device (such as the mobile device itself) in a trusted environment (secure pairing refers to mutual exchange of certificates and mutual trust), security is usually performed before leaving the factory. The secure pairing of the device and the host device, however, the host device is often in ...

Problems solved by technology

[0003] In the prior art, in order to ensure secure pairing between the security device (such as the fingerprint module) and the host device (such as the mobile device itself) in a trusted environment (secure pairing refers to mutual exchange of certificates and mutual trust), security is usually performed before leaving the factory. The secure pairing of the device and the host device, however, the host device is often in an untrusted environment during assembly, testing, maintenance, etc., and there is no technology for secure pairing between the security device and the host device in an untrusted environment in the prior art Program
