Enhancing Data Storage Integrity in Cloud Environment by mitigating Repudiation using CS-MPNR
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 3
Abstract
Cloud computing is envisioned as the next generation architecture of IT organisation. It makes the users need of their data to be available wherever they are. Although recent emerging technology Cloud has many striking features, it also has some security dreads. So the users find it difficult to trust the providers who store their data. The vulnerabilities in Cloud storage lead to some loopholes for the attackers to snatch the data and modify or delete it. Data to be secure such as medical reports, industrial files, and other personal and important data should be protected enough from the repudiation problems to maintain Data integrity. To overcome these challenges, a novel new CS-MPNR [Chaining Signature-Multi Party Non Repudiation] protocol is proposed, which is a method that uses Chaining Signature [CS] acting as a link of signature to have a follow up of the chained users and lessens the Disputation. For the need of challenging the providers and also to have fairness during the transaction of data, TTP (Trusted Third Party) is allowed, which reduces the users work of checking the data completeness. Not only it reduces repudiation problem, it also maintains and upholds Data Integrity. Performance evaluation shows that the computational time is reduced with provable security
