Cong Wang, a Ph.D. candidate at the Illinois Institute of Technology, will present 'Secure Computation Outsourcing in the Public Cloud'. A reception will be held at 3:30 p.m. in Room 348 with the presentation following at 4:00 p.m. in 115 Avery.
His abstract is as follows:
"Cloud computing enables end-users with limited computational resources to outsource large-scale computational problems to the public cloud, where massive computational power can be easily utilized in a pay-per-use manner. However, security is the major concern that prevents the wide adoption of computation outsourcing, especially when end-user's confidential data are processed and produced during the computation. Therefore, enabling secure computation outsourcing mechanisms in the public cloud becomes imperative while being challenging. In this talk, I will present our recent research efforts on secure outsourcing of the widely applicable linear programming computations. Our contribution is three-fold. Firstly, the proposed mechanism not only protects the sensitive input and output of the linear programming but also guarantees the correctness of the computation result. Secondly, the proposed mechanism provides significant computational savings as the end-user only needs to perform much less amount of work than solving the linear programming locally. Thirdly, our design is practically feasible in the sense that the related workload to both the end-user and the cloud can be completed within a reasonable amount of time. In this talk, I will also discuss some other on-going research related to data service outsourcing security in cloud, including secure search over encrypted cloud data and secure and dependable storage service outsourcing."
Wang received his B.E and M.E degrees from Wuhan University, China, in 2004 and 2007, respectively. His research interests are in the areas of cloud computing and security, with a current focus on secure data service outsourcing and secure computation outsourcing in the public cloud. He has published more than 20 papers that appear in prestigious venues including IEEE TC, TPDS, TSC, IEEE INFOCOM'10-12, ICDCS'10-11, ESORICS'09, etc. Cong’s research is well recognized, and his publications have received over 400 citations, according to Google scholar. He was an intern at Palo Alto Research Center in summer 2011 and contributed to two pending US patents.
