Intelligent medical cross-domain authentication method based on combination of block chain and IBC

Abstract

The invention discloses an intelligent medical cross-domain authentication method based on combination of a block chain and IBC. The method comprises the following steps: deploying medical Internet of Things equipment in each medical domain; setting a key management server, and generating a private key by taking the identity information of the medical Internet of Things equipment as a public key; setting a block chain server and an open source block chain platform, and adding the block chain server into an alliance chain; enabling the block chain server to receive identity public key information related to each domain from the key management server, and write the identity public key information into an alliance chain account book; and setting a cross-domain identity authentication proxy server, requesting the block chain server to query identity data, and verifying identity validity according to a query result. According to the method, the block chain technology is adopted to construct the trust relationship among the domains instead of putting trust in a third party, the block chain account book is maintained by all participant domains and is more persuasive than the previous single CA maintenance, the public key calling process is converted into one block chain account book read-write operation by utilizing the alliance block chain account book and the chain code, and public key calling is simple and easy.

Description

technical field [0001] The invention belongs to the technical field of computer security, and in particular relates to remote medical equipment, IBC-based cross-domain authentication technology and blockchain technology, and specifically proposes a smart medical cross-domain authentication method based on the combination of blockchain and IBC. Background technique [0002] The medical industry is closely related to people's healthy life. Under the trend of rapid development of big data and cloud computing, it has also been favored by the Internet of Things industry, and a smart medical system has been developed. Most of the information stored in the smart medical system is the patient's confidential and sensitive information. Once maliciously accessed by illegal personnel, it will bring losses to both the patient and the hospital, causing huge social impact. Take a simplified application scenario as an example, which involves two domains under the smart medical system, namel...
