Abstract

The embodiment of the invention provides a cross-domain access authentication method and system based on a block chain, and is applied to the technical field of computers. The method comprises the following steps: when a target device performs cross-domain access for a target trust domain, signing and encrypting a device identifier of the target device by using an intra-domain private key and a cross-domain private key of the target device to obtain first information, and sending the first information to a first gateway; encrypting, by the first gateway, the information included in the first information by using the intra-domain public key and the cross-domain public key of the second gateway to obtain second information of the target device, and sending an access request carrying the second information to the second gateway in the target trust domain; and decrypting, by the second gateway, the second information by using the cross-domain private key and the intra-domain private key of the second gateway to obtain a device identifier of the target device, verifying the device identifier of the target device, and determining a key when the target device performs cross-domain access on the target trusted domain after the verification is passed. The invention solves the problem of management pressure of the cloud server.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a block chain-based authentication method and system for cross-domain access. Background technique [0002] The trust domain composed of devices and cloud servers is an important part of the Internet of Things, and there are differences in authentication methods between different trust domains. Due to the limited resources in the same trust domain, there are more and more cross-domain access requirements for devices in the Internet of Things. [0003] In the prior art, when the target device is registered in domain A, the cloud server in domain A generates the first key for the target device, and publishes the device ID and the first key of the target device to the consortium chain; when the target device in domain A When a device accesses domain B, the cloud server in domain A sends an access request carrying the device ID of the target device to the cloud server in d...
