一种新型的Merkle哈希树云数据完整性审计方案
New type of Merkle Hash Tree for integrity audit scheme in cloud storage
摘要
Abstract
There are some imperfections in the authenticated data structure used for cloud data integrity audit schemes. This paper thus presents a data structure named Binary Ordered Merkle Hash Tree(BO-MHT). In order to improve the utilization efficiency, each node stores the information of data blocks. The paper uses the local authority root node to shorten the length of authentication path. A version identifier is added to maintain the freshness of information at each node. With the provable data possession model, a new integrity auditing scheme is implemented via the BO-MHT structure. Theoretical analysis and experimental results show that the proposed scheme has realized the integrity auditing function which can effectively reduce the computational and communication costs, and has a high audit efficiency.关键词
