基于Merkle哈希树的云存储加密数据去重复研究
Deduplication with encrypted data based on Merkle Hash tree in cloud storage
摘要
Abstract
Although convergent encryption has effectively solved the contradiction between encryption and deduplication,it still faces many security problems.Aiming at the problem of conventional convergence encryption vulnerable to dictionary attacks,this paper proposes a convergence encryption scheme based on Merkle Hash tree,which realizes data deduplication, strengthens the confidentiality of data and effectively avoids data dictionary attacks by performing additional cryptographic operations. To overcome the problem that convergent keys linearly increase with the number of users, key sharing mechanism is designed,which can reduce more storage space of convergent keys.关键词
