Problems solved by technology

[0003] The above process has the following two problems. On the one hand, in order to ensure the security of the data in the data exchange process, the data sender transmits multiple data to the exchange server, resulting in a decrease in the efficiency of data exchange.
On the other hand, the data exchange server, as a centralized exchange server, the data exchange process is opaque to the requesting end and the data receiving end. After the data exchange process is tampered with, it is impossible to trace which link has been tampered with

Embodiment 1

[0044] Such as figure 1 As shown, Embodiment 1 provides a method for trusted offline data exchange of encrypted network based on blockchain. The data exchanged in the blockchain-based encrypted network offline data trusted exchange method is stored in the blockchain and locked through the data exchange protocol, and the data receiving end unlocks it through the secret key to obtain the data, preventing users from illegal sources from intercepting The process of exchanging the identity of the requesting end and the receiving end, registration, distribution, and verification of data is completed through the blockchain, and the identity information stored in the blockchain cannot be tampered with, ensuring that the identities of the data receiving end and the requesting end are safe and credible, and simplifying the verification of identity information. Improve data exchange efficiency.

[0045] Specifically, the blockchain-based encrypted network offline data trusted exchange m...

Embodiment 2

[0094] see figure 2 , the present invention also provides a trusted data exchange device based on block chain. The trusted data exchange device based on blockchain includes an identity distribution module, a data sending module, a data storage module and a data unlocking module.

[0095] In this embodiment, the identity distribution module is adapted to issue verification identities to the exchange requesting end and the data receiving end through the blockchain-based trusted data exchange device. Specifically, the step of issuing a verification identity to the exchange requesting end and the data receiving end through the block chain, that is, the exchange requesting end and the data receiving end are connected to the trusted data exchange device based on the block chain, and the data is credible. The exchange device assigns account identities and device identifications to the exchange requesting end and the data receiving end, stores the account identities and device ident...

Embodiment 3

[0139] The embodiment of the present invention also provides a computer-readable storage medium, where one or more instructions are stored in the computer-readable storage medium, and when the one or more instructions are executed by a processor, the method described in Embodiment 1 can be realized. The blockchain-based encrypted network offline data trusted exchange method provided.

[0140] Specifically, the exchanged data is stored in the blockchain and locked through the data exchange protocol. The data receiving end unlocks it through the secret key to obtain the data, preventing users from illegal sources from intercepting the data, and exchanging the identities of the requesting end and the receiving end. The registration, allocation, and verification processes are completed through the blockchain, and the identity information stored in the blockchain cannot be tampered with, ensuring the security and credibility of the identities of the data receiving end and the reques...

Abstract

The invention relates to a trusted offline data exchange method and device based on a block chain encrypted network. The exchange request end encrypts the original data with a private key signature and sends a data exchange request to a trusted data exchange device; the trusted data exchange device According to the data exchange protocol, the data is converted and stored in the blockchain, and the push message is sent to the data receiving end; the data receiving end unlocks the pushed data to complete the data exchange. The exchanged data is stored in the blockchain and locked through the data exchange protocol. The data receiving end unlocks it through the secret key to obtain the data, preventing users from illegal sources from intercepting the data, exchanging the identity registration, distribution, and The verification process is completed through the blockchain, and the identity information stored in the blockchain cannot be tampered with, ensuring the security and credibility of the identities of the data receiving end and the requesting end, simplifying the verification of identity information, and improving the efficiency of data exchange.

Description

technical field [0001] The invention relates to the field of data exchange, in particular to a trusted exchange method and device for off-line data in an encrypted network based on blockchain. Background technique [0002] The general process of data exchange includes that the data exchange request end sends an exchange request to the data exchange server, the data exchange server generates a session key and returns it to the exchange request end, and the exchange request end encrypts the public key of the receiving end and the data to be exchanged with the secret key and sends it to The exchange server, the data exchange server encrypts the exchange data through the public key of the receiving end and sends it to the data receiving end. After receiving the data, the data receiving end uses its own private key to decrypt the data and obtain the exchanged data. [0003] The above process has the following two problems. On the one hand, in order to ensure the security of the d...
