Boffins propose NSA-proof crypto for cloud computing

It’s more likely that the NSA has devoted its efforts to key capture and side-channel attacks rather than brute-forcing its way through ciphertext en masse – but it’s also true that our crypto maths won’t last foreverm which draws attention to projects like this one (PDF), which is looking at protection of multi-party computation (MPC) activities.
According to Phys.org: “The idea behind Multi-Party Computation is that it should enable two or more people to compute any function of their choosing on their secret inputs, without revealing their inputs to either party. One example is an election; voters want their vote to be counted but they do not want their vote made public.”…
As The Register understands the system, this might also be useful in cloud-based collaboration, since it would protect Average Joe’s data against the rest of the world, including Average Joe’s boss, if it so happened that her machine were compromised. The aim of the work by a UK-Danish collaboration is to strap the supercharger onto a protocol called SPDZ – pronounced Speedz – to give it real-world performance…
