Decentralized Data Storage Scheme with Updatable Ciphertext
摘要
Abstract
In recent years,the maturity of cloud computing technology has led to more and more data stored on the cloud serv-ers.The traditional centralized storage architecture is difficult to meet the requirements of data reliability at a low cost.Most compa-nies choose distributed data storage.The current distributed storage mode requires the management server to distribute data blocks and lacks the efficient operation of ciphertext update.This causes some security problems,such as single point of failure and data leakage.According to the requirements of ciphertext updating and decentralization,a decentralized data storage scheme with cipher-text updatable is proposed.The ciphertext update of this scheme includes data ciphertext and key ciphertext.They are updated with the help of the corresponding update algorithm,so as to ensure the reliability and security in data storage and data access.With the help of Ethereum,this scheme replaces the management server in the distributed storage scheme with smart contract to realize de-centralization.The experimental results show that the computational cost of this scheme is lower than that of the current scheme and the cost of functions in the smart contract is also within the acceptable range of users.关键词
