Embodiment 1

[0074] The main purpose of the present invention is to integrate blockchain technology into the data transmission system, thereby improving the security of the data transmission system, and more specifically, improving the security of data storage, sharing, and access in the data transmission system. Security includes at least privacy, confidentiality, etc. Data transmission systems such as the data transmission system of the Internet of Things, data transmission systems related to optical communication, Internet data transmission systems, and LAN data transmission systems, the blockchain nodes in the above systems, that is, the corresponding computing devices have a large amount of data storage requirements , so the computing device uploads the corresponding data to the cloud storage system.

[0075]Preferably, blockchain technology can be directly applied to cloud storage architecture, and each node can be a storage space demander or provider. Since there may be a large amo...

Embodiment approach

[0077] According to a preferred embodiment, the request information sent by the node sending user includes at least a file encrypted with the first public key / second public key of the node target user and the first public key / second public key of the node sending user. The request message is unsigned to prevent hijacking attacks. The request information is broadcast by the smart contract unit 400 to the node pool. The trusted supervisory node 300 can obtain the request information through the node pool. In the case that the node target user obtains the request information sent by the node sending user based on the address represented by its first public key / second public key, the node target user is configured as follows:

[0078] partially decrypting the first information digest represented by the first public key / second public key of the node target user in the request message based on its first private key / second private key;

[0079] Encrypting and generating a first dig...

Embodiment 2

[0101] The present invention also provides a block chain-based data transmission method. Such as figure 2 As shown, the methods include at least:

[0102] S100: Generate at least a first public key, a first private key matching the first public key, a second public key matching a second private key matching the second public key based on an asymmetric encryption algorithm, and use the first public key, the second private key A private key, a second public key and a second private key are distributed to registered node users.

[0103]Preferably, the first public key is not associated with the second public key. The first public key, the first private key, the second public key and the second private key are stored in the trusted supervision node 300 . The user node only stores the first public key / second public key and the corresponding first private key / second private key. Preferably, the node user obtains its first public key and second private key through the smart cont...

Abstract

The invention relates to a data transmission system and method based on a block chain, and the system at least comprises an intelligent contract unit which is configured to at least generate a first public key, a first private key matched with the first public key, a second public key, and a second private key matched with the second public key based on an asymmetric encryption algorithm, and allocates the first public key, the first private key, the second public key and the second private key to a node user registered in the identity management unit, the first public key and the second public key are not associated, and the first public key, the first private key, the second public key and the second private key are stored in a trusted supervision node; the user node only stores the first public key / second public key and the corresponding first private key / second private key; a node sending user sending a data request needs to interact with a node target user at least twice so as toestablish reliable access through at least two of a first public key, a second public key, a first private key and a second private key in the trusted supervision node.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a data transmission system and method based on block chains. Background technique [0002] With the continuous maturity of digital information technology, it is particularly important to transform more industries into intelligent and information-based high-end industries. At present, there are many problems in many industries, such as lack of data credibility and information asymmetry. More specifically, ordinary C-end customers cannot obtain real and reliable information, and B-ends in a competitive environment monopolize information based on commercial interests. [0003] In fact, both merchants and customers attach great importance to the security of resources and data. Security cannot be guaranteed, which means that there is a lack of information security. There will be no mutual benefit. In terms of security, in order to protect the privacy or security of dat...
