Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] The IBE / IBBE-based data sharing method in this embodiment requires the use of a blockchain sharing platform. Each data sharing user accesses the blockchain network of the blockchain sharing platform as a node, and each data sharing user who can access the blockchain sharing platform has a corresponding user ID. The blockchain sharing platform has a directory management module for managing user IDs and corresponding data matching information. The blockchain sharing platform also has a private key generation center for generating private keys. The private key generation center issues IBE / IBBE private keys through encrypted channels according to the application of each user ID. The valid period in the valid period character string in the following public key replaces the IBE / IBBE private key of each user ID.

Abstract

The invention relates to a data sharing method based on IBE / IBBE, in which a data requesting user sends a data sharing request packet to a block chain sharing platform, and the block chain sharing platform sends the data requesting user to the data requesting user according to the data sharing request information in the data sharing request packet Send the data source user ID; the data request user sends a data sharing request packet to the data source user, and the data source user sends the shared data to the data request user according to the data sharing request information, and then the data request user obtains the shared data. Based on the IBE / IBBE data sharing method in the present invention, the transmission of shared data does not require the exchange of public keys and private keys, and does not require the participation of a third party. Data sharing is faster and safer, and it also effectively protects data requesting users and data sharing methods. Source User Privacy.

Description

technical field [0001] The invention relates to an IBE / IBBE-based data sharing method. Background technique [0002] With the development of information and communication technology, the issue of network information security becomes more and more important. The use of cryptography technology in the process of network information transmission can effectively guarantee data security. Public Key Infrastructure (PKI) is a general technical specification and standard that uses the principle and technology of asymmetric encryption algorithm to realize and provide security services. With the improvement of the PKI system and the development of encryption technology, the secure interaction of network information has made better progress, but the implementation and application process of the PKI system is relatively cumbersome and complicated, and the deployment also requires a lot of funds. These are the fields of information security. A cause worthy of vigorous study and attention...
