Hi, Im working on a school project about vulnerabilities of current cryptography methods and its implementation in critical infrastructure. I have already done some research, but to be honest there is not much about it, it basicaly boils down to side-channel attacks (this is more of a implementation problem than cypher itself), quantum computers (mostly just save now-decrypt later) and social engineering (phishing, etc.- again, not so much cypher itself). Is there anything that I have overlooked that would be worth it to add to this?
