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.

[0029] Such as figure 1 As...

Abstract

The invention relates to a data sharing method based on IBE / IBBE, and the method comprises: a data request user transmitting a data sharing request data packet to a block chain data sharing platform,and the block chain sharing platform transmitting a data source user ID to the data request user according to the data sharing request information in the data sharing request data packet; and the datarequest user sending a data sharing request data packet to the data source user, and the data source user sending shared data to the data request user according to the data sharing request information, so that the data request user obtains the shared data. According to the data sharing method based on IBE / IBBE, exchange of a public key and a private key and participation of a third party are notneeded during transmission of the shared data, data sharing is faster and safer, and privacy of a data request user and a data source user is effectively protected.

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 universal technical specification and standard that uses asymmetric encryption algorithm principles and technologies to implement 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...
