Abstract

The invention discloses a drug information encryption and tamper-proofing method based on a block chain and an advanced encryption standard, and relates to the technical field of drug platforms, the method comprises the steps: building a block chain network, deploying an intelligent contract, and generating an asymmetric key pair; dividing the medicine information into different levels according to the sensitivity degree of the medicine information, and encrypting the medicine information of different levels by adopting different encryption modes and keys; the encrypted drug information is uploaded to a block chain network, and the drug information and corresponding metadata are packaged and recorded to a block chain by the smart contract; a receiver submits an access request through a client application, the smart contract performs permission verification according to identity information of the receiver and the information level of the access request, an access token is generated and sent to the receiver after the verification is passed, and the receiver decrypts data by using a private key or a symmetric key of the receiver for confidential level information. The method is remarkable in the aspects of data security, integrity, management efficiency, supervision transparency, industry trust and the like.
