IOTA-Based Data Encryption Storage and Retrieval Method

Abstract

At present, the traditional blockchain for data storage and retrieval reflects the characteristics of slow data uploading speed, high cost, and transparency, and there are a lot of corresponding problems, such as not supporting private data storage, large data operation costs, and not supporting Data field query. This paper proposes a method of data encryption storage and retrieval based on the IOTA distributed ledger, combined with the fast transaction processing speed and zero-value transactions of the IOTA blockchain, through the Masked Authenticated Messaging technology, so that the data is encrypted in the data stream. The form is stored in the distributed ledger, quickly retrieved through the field index mechanism established by the data form, and the data operation is carried out on the chain. Experimental results show that this system has high storage, encryption and retrieval performance, and good practicability.
