Microsoft Research Unveils VC3 Cloud Workload Privacy Project
The company advances cloud data privacy and security with a new technology called Verifiable Confidential Cloud Computing (VC3).Extending its "lockbox" approach to securing data on the cloud, Microsoft's research arm today announced a new technology dubbed Verifiable Confidential Cloud Computing, or VC3. Last year, the Redmond, Wash.-based software giant announced a new process for safeguarding cloud data called a lockbox. Encompassing a set of technologies, along with strict policies and IT practices at the company's cloud data centers, the approach essentially places customers in complete control of their data and requires that they issue their approval before even Microsoft's own administrators can access protected information. Now, Microsoft is using a similar strategy to protect cloud workloads. "This new technology, called VC3, uses enhanced security measures to make sure that your data is locked in a special lockbox, even when you are accessing it, to make calculations or other transactions," stated Allison Linn, a Microsoft Research writer, in a May 18 announcement. "The technology ensures that even the employees of the company hosting you in the cloud have no way of accessing or manipulating your data."
In an abstract of a paper presented during this week's IEEE Symposium on Security and Privacy in San Jose, Calif., Microsoft's researchers stated that VC3 is "the first system that allows users to run distributed MapReduce computations in the cloud while keeping their code and data secret, and ensuring the correctness and completeness of their results." MapReduce is a popular framework used to harness the power of several servers to process massive data sets.
