Decentralized searchable encryption scheme based on dynamic accumulator

Abstract

Since the flourish of the blockchain technology, a series of applications based on blockchain technology are emerging, and the decentralized storage service becomes the killer App in the decentralized markets, such as StorJ, Filecoin. Comparing with the centralized storage, decentralized storage are more secure, cheaper and more scalable. However, client’s privacy cannot be protected in existed decentralized storage apps. The idea of implementing the searchable encryption scheme with decentralized storage was proposed to improve the user’s privacy and utilizing the dynamic accumulator to improve the search efficiency of the searchable encryption scheme.
