Abstract

The invention discloses a symmetric searchable encryption method based on a PBFT consensus mechanism, and relates to the technical field of data processing methods. The method comprises the following steps: a preparation stage, a retrieval stage, a consensus stage and an updating stage. According to the method, a block chain technology and a searchable encryption technology are combined, so that the disclosure, transparency and traceability of a data retrieval process can be ensured; a symmetric searchable encryption method including data verification, data updating and node behavior supervision is established through an improved PBFT consensus, so that the transaction fairness between the user and the server can be ensured, the one-to-one correspondence between the user retrieval request and the retrieval result provided by the cloud server is ensured, and the method is real and reliable. And the credibility between the user and the cloud server can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of data processing methods, in particular to a symmetric searchable encryption method based on a PBFT consensus mechanism. Background technique [0002] The advent of the information age has made data storage and sharing a hot topic for many scholars, and the emergence of cloud storage provides people with a more convenient and economical data storage method. Computing resources and storage resources on the cloud have become a kind of Internet infrastructure. Through cloud computing technology, manufacturers establish network server clusters to provide online software services, hardware rental, data storage, computing analysis and other services to different types of customers. The well-known foreign cloud service providers include Dropbox, a cloud network storage tool, Amazon simple storage service (Amazon simple storage service), and Microsoft's cloud computing platform Windows Azure. In recent years, do...
