What are some standard assumptions made in showing the security of a block cipher?
For example, is it commonly assumed that $P\not=NP$? To this end, are there any block ciphers whose security does not rest on the assumption that $P\not=NP$, and if so what are the assumptions?
Furthermore, do there exist any block ciphers that are provably secure under some set of assumptions?

The first question about standard assumptions is too broad. But, see this and this for some information. – forest Apr 21 '22 at 20:46
