  2. Data Integrity as a Service in the Cloud Surya Nepal, Shiping Chen, Jinhui Yao, Thilakanathan

  3. Topics : • Introduction • Related Work • Trusted Cloud Storage Architecture • Data Integrity as a Service • Prototype System • Conclusion

  4. Introduction • Services provided by Cloud • Security • Data Integrity

  5. Related Work • Storage Server Technologies Mirroring, RAID, Checksum • Protocols • PDP, PoR • Standards • SNIA CDMI • Storage Architecture • DIaaS

  6. Trusted Cloud Storage Architecture

  7. The Architecture contains 5 key components • Client Application Portal (CAP) • Trust Management Service(TMS) • Key Management Service(KMS) • Cloud Storage Service(CSS) • Integrity Management Service(IMS)

  8. Data Integrity as a Service

  9. Diaas describes models and protocols for Integrity Management Service… Four different scenarios: • Model CSS-Y IMS-U • Model CSS-Y IMS-T • Model CSS-N IMS-T • Model CSS-N IMS-U

  10. Model CSS-Y IMS-U Data Uploading Protocol

  11. Data Downloading Protocol

  12. Model CSS-Y IMS-T Data Uploading and Downloading

  13. Model CSS-N IMS-T Data Uploading and Downloading

  14. Model CSS-N IMS-U This model is most generic model in comparison to the other three models. This model doesn’t make any assumptions on trustworthiness of both CSS and IMS.

  15. Performance Evaluation

  16. Performance of Downloading different files

  17. CONCLUSION: Data Integrity is one of key aspects of cloud data security. DIaaS is used to address the data integrity concerns in cloud storage service by Implementing Integrity Management Service(IMS).
