You mean like a one-time pad? I'm sure the folks at NIST know about it; it is completely unbreakable and had been around for a while. Use is not really practical though, so typically reserved for very specific use cases.
- upofadown 4y agoOne time pads fall into the symmetrical encryption category. There is no huge issue with symmetrical encryption with respect to the possibility someone might invent a quantum computer. The things people are working on for a post quantum world and NIST is attempting to standardize are in the asymmetrical encryption category.
- bawolff 4y agoThis is a silly nitpick. I think its pretty well understood from context i meant a practical quantum safe key agreement algorithm. One time pad cannot be used for that purpose at all, let alone practically.
