Abstract

The invention discloses a symmetrical searchable encryption method based on a PBFT consensus mechanism, and relates to the technical field of data processing methods. The method includes the following steps: a preparation phase, a retrieval phase, a consensus phase and an update phase. The method described in this application combines blockchain technology with searchable encryption technology, which can ensure the openness, transparency and traceability of the data retrieval process; and establishes a set of data verification, data update and node behavior supervision through the improved PBFT consensus The symmetric searchable encryption method inside can ensure the fairness of the transaction between the user and the server, and ensure the one-to-one correspondence between the user's search request and the search results provided by the cloud server, and it is authentic and reliable, which can effectively improve the trust between the user and the cloud server Spend.
