Trustzone-based hyperledger data trusted encryption method

The invention discloses a Trustzone-based hyperledger data trusted encryption method, which is specifically implemented according to the following steps: step 1, establishing a hyperledger network, and initiating data encryption transaction calling for a chain code; step 2, the chain code forwards the incoming chain code calling information to the client application; step 3, the client application opens a session with the trusted application after receiving the information, the trusted application encrypts the data, and then returns the key, the encrypted data and the account book writing request to the client application; step 4, the client application sends a key, data and an account book writing request to the chain code, and the chain code sends a confirmation reply to the client application; 5, the client application forwards a confirmation message to the trusted application, and the trusted application replies an execution completion response to the client application; and step 6, the client application
