Embodiment
[0051] In this embodiment, a method for depositing certificates in blockchain includes the following steps for depositing certificates:
[0052] Step A: Execution by the client.
[0053] Step A-1. The client generates a client random number.
[0054] Step A-2, the client sends the client ID, client random number, target data to be authenticated and address information to the server through an encrypted channel. Client ID, client random number, target data to be authenticated and address information are encrypted and transmitted through encrypted channel SSL, TLS or HTTPS.
[0055] Step B: Execute on the server side.
[0056] Step B-1. The server side receives the client identification, client random number, target data and address information from the client through the encrypted channel.
[0057] Step B-2, the server side generates a server side random number.
[0058] Step B-3, the server sends the server identifier and the server random number to the client through an e...

The invention provides a block chain evidence storage method, and the method comprises the steps: enabling a client to take a secret key, a client random number, a server random number, a client identifier, a server identifier, target data and address information as input according to a preset operation, and generating a client verification code; the server side takes the secret key, the client side random number, the server side random number, the client side identification, the server side identification, the target data and the address information as input according to preset operation to generate a server right verification code; and when the server verifies and compares that the client verification code is equal to the server authentication code, the server writes the evidence storage parameter, the client identifier, the server identifier, the address information, the client random number, the server random number and the client verification code into the block chain. The method has the advantages that only the evidence storage identifier, the client identifier, the server identifier, the address information, the client random number, the server random number and the client verification code are uploaded to the block chain; even if a large amount of data needs to be stored, a large amount of time and on-chain storage cost are not needed.
Description
technical field [0001] The invention relates to a block chain certificate storage method. Background technique [0002] Blockchain deposit certificate is currently one of the main application solutions in the blockchain field, and has been applied to many fields such as Internet finance and intellectual property. The blockchain deposit certificate mainly uses technology as a virtual third-party identity, and records the target data to be stored in the blockchain after a series of processing to ensure the integrity of the target data. [0003] The current blockchain-based certificate storage schemes are mainly divided into two categories: [0004] The first category is to store target data files, storage time and other information on the chain; [0005] The second type is to generate a hash digest of the target data file through a hash function; then store the hash digest, storage time and other information on the chain. [0006] Most of these two certificate storage schem...
