Secure computation enables users to compute some result without revealing the inputs. Privacy schemes that are shown to only reveal outputs are said to have input privacy. However, learning these outputs still tells you something about the private inputs. The important question is: “how much?” The Defense Advanced Research Projects Agency (DARPA) Brandeis program aims […]
Today, Microsoft announced our joint work on ElectionGuard and the upcoming release of the software development kit. This SDK will be freely available, and can be used to enable end-to-end verifiable (E2E-V) elections around the world. An E2E-V election uses cryptography to produce proofs that an election has been run correctly. In a properly implemented […]
This article originally appeared in the Fall 2018 edition of the U.S. Cybersecurity Magazine When obdurate isolationist Woodrow Wilson won 1916 re-election under the slogan, “He kept us out of the war!”, he hadn’t anticipated a simple act of data sharing. On January 17, 1917, Room 40 (British Naval Intelligence) finally decrypted the infamous German “Zimmerman […]
This is a followup to our previous post, which introduces our research exploring new strategies for protecting legacy applications on the DARPA CFAR program. Briefly, our approach is to generate variants of a target application that behave the same when given benign input but different when given malicious input. Then we run a set of […]
On the DARPA CFAR program, the Galois “RADSS” team is developing new ways to mitigate memory corruption attacks against legacy C/C++ systems without requiring finding and fixing each individual bug. CFAR is about “Cyber Fault-tolerant Attack Recovery” and our general approach is: Given some application to defend, generate multiple variants of that application such that […]
