基于无证书的动态云存储审计技术研究
Research on Certificateless Dynamic Cloud Storage Audit Technology
摘要
Abstract
Due to the large amount of data and the loss of physical control by users,dynamic operations of large-scale data in cloud storage face dual challenges of efficiency and security.Therefore,based on the certificate-less public key cryptosystem,a cloud storage audit scheme that can flexibly and efficiently support dynamic opera-tions is proposed,thereby avoiding complex certificate management and key escrow issues.A Merkle Hash Tree structure based on Skip Lists(SL-MHT)was designed in the scheme,which organically combines the probability balance characteristics of skip lists with the perfect balance of full binary trees to support efficient dynamic opera-tions and integrity verification of large-scale data.At the same time,in order to prevent third-party auditors from ob-taining data content during the audit process,random masking technology was introduced to achieve data privacy protection.The safety analysis and experimental results indicate that the scheme is safe and effective.关键词
