Merkle Hash Tree based Techniques for Data Integrity of Outsourced Data
نویسندگان
چکیده
One of the problems associated with outsourcing data to cloud service providers is the data integrity of outsourced data. In this paper we present data integrity techniques for the outsourced data. Data integrity encompasses the completeness, correctness and freshness of the data. This paper focuses on the Merkle Hash Tree based data integrity techniques. It also presents the techniques for storage and retrieval of Merkle Hash Tree based authentication data to and from cloud data service provider. Critical analysis of the Radix Path Identifiers, a technique for storage of Merkle Hash Trees in the databases, is presented in this paper.
