“SecureCTask: Secure Tasking over Untrusted Third-Party Cloud Servers”


Friday, November 3, 2017 - 11:15am to 12:00pm


Pradeep Atrey, Associate Professor, SUNY Albany


Marston 132


Today, it is a common practice to outsource small as well as large-scale data storage and computing tasks to the third-party high-performance computing servers such as cloud data centers. Online editing tools GoogleDoc and Microsoft, storage avenues Google Drive and Microsoft One Drive, PDF merge tool, and email service Gmail and Yahoo are examples of outsourcing the tasks. These solutions deliver highly scalable and virtualized resources to efficiently perform the required services; however, since these third-party service providers can often be untrustworthy, their use brings in serious security and privacy concerns. In this talk, I will present our recent work focusing on secure cloud-based computations. We call our framework SecureCTask, in general; which we instantiate for various tasks such as Word document editing (SecureCEdit), PDF merging (SecureCMerge), emailing (SecureCEmail) and data deduplication (SecureCDedup). The SecureCTask framework aims to perform the required tasks on the encrypted data in an outsourced environment, preserving the security and privacy of the data.
