What cryptography might do in future but can not do?
I have an opinion that Cryptography is a top notch of all the Computer Sciences. But I do not know any sci-pop resources with cryptography-centered content. So, if you are familiar of what is going on in crypto circles, please share some of your opinions or maybe links about some possible break-throws.
Check out Bruce Schneier's blog. It's about as good as it gets, though it may be a little advanced. Computerphile made lots of videos on cryptography as well.
Setup a feed of Hacker News articles with keywords cryptography, homomorphic, and encrypt. You may want to see more mathematical results with keywords lattice or elliptic. Or, technical results with Diffie or TLS.
