Cyril Guyot is a Senior Engineer for the research division of Hitachi Global Storage Technologies in San Jose, California. His current research interests are: storage security, cryptographic primitives (hyperelliptic curve cryptography, pairing-based cryptography), and secure computation.

He received a Diplôme d'Ingénieur in 2000 from the École Centrale Paris in Paris, France, and a M.S. in Mathematics in 2001 from the University of Toronto in Toronto, Canada.

He has 7 years of experience in the security industry. As a mathematician/developer for the Toronto based start-up Karthika Technologies, he researched and developed software implementations of novel cryptographic algorithms based on elliptic and hyperelliptic curves. He later joined Kasten Chase Applied Research in Mississauga, Canada, where as leader of the Advanced Technology Group he supervised a group of researchers and engineers in researching and implementing security
protocols and cryptographic algorithms for storage systems.

Since 2006, he has been a member of the Storage Architecture Group at Hitachi Global Storage Technologies' research division in San Jose, California. Aside from his research work, he has been involved in the development of security specifications for storage systems under the aegis of the TCG Storage Workgroup where he chairs the Storage Compliance and Conformance Subgroup.

Presentation

Securing Stored Data in the Cloud

This presentation is about the deployment of storage-device security as a means of securing the cloud, and overcoming the practical issues that widespread data-at-rest encryption might pose.

I will first provide a general view of the security issues that cloud storage faces. I will then show how the storage security architecture recently developed by the Trusted Computing Group provides a practical solution to some of those issues. I will go on to describe how the universal deployment of data-at-rest encryption systems can lead to fundamental changes in the usability of the stored data for cloud storage providers. Finally, I will show how recent cryptographic research can help those storage providers recover some of the lost abilities -- searchability, computability etc... -- without
compromising security.
