REMOTE DATA AUDIT METHOD BASED ON OPTIMIZED DIVIDE AND CONQUER TABLE
摘要
Abstract
In order to reduce the computational and communication costs in remote big data auditing, an efficient remote big data auditing method was proposed.First,the data owner generated the public key and secret key through the KeyGen algorithm.Then,in order to verify the integrity of the outsourced data block,the data owner generated a random data block and a challenge message.When the cloud server received the challenge message, the data owner remotely checked the correctness of the file based on the algebraic signature of the data block tag.At the same time, the data structure of the divide and conquer table(DCT)was designed and optimized to support operations such as dynamic data updates.Experimental results showed that the proposed DCT data structure effectively reduced the processing time of dynamic data update operations by reducing the number of data block movements.Compared with other methods, the proposed method significantly reduced the computational cost of dynamic data updates for large -scale outsourced documents in cloud computing,and had security.关键词
