It was a really nice article.
Coincidence? Today I've switched my default search engine to DuckDuckGo instead of Google. I'll give it a one week try.
I am a coFounder for an electric smart grid company. A major long term problem for us is to find a way to provide our customer the complete propriety of their data.
How could we manage data without knowing much about it? Is there any simple way of encrypting some data and be able to make some transformation to them?
Something like:
F(enc(x)) = enc(F(x)) ?
We are managing mostly consumption values, it would be nice to provide functions like the mean, max, FFT? I don't know.
Thanks for any idea.
- yummyfajitas 16y agoI don't think there are any practical homomorphic encryption schemes at this point. Most only support very simple operations. http://en.wikipedia.org/wiki/Homomorphic_encryption http://en.wikipedia.org/wiki/Homomorphic_encryption
- jerf 16y agoYou're looking for this: http://en.wikipedia.org/wiki/Homomorphic_encryption#Fully_homomorphic_encryption http://en.wikipedia.org/wiki/Homomorphic_encryption#Fully_ho... Practicality right now is minimal. My intuition says it is going to stay that way, but who knows.
- Xk 16y agoIt's not totally impractical. Paillier, for example, has nice applications in electronic voting (since you can sum votes without reading who those votes were for). http://en.wikipedia.org/wiki/Paillier_cryptosystem http://en.wikipedia.org/wiki/Paillier_cryptosystem But yeah, anything more than that is currently not all that practical.
