I suggest merging unpredictable permutation into pseudorandom permutation. The current description in these articles sounds very similar, so I suspect a single article covering both would need only a short paragraph describing the differences (if any) between them. --DavidCary (talk) 12:29, 23 November 2013 (UTC) Done[reply]

I've never heard of "unpredictable permutation" and I'm an experienced cryptographer. As far as I can see, it appears to be a concept used in a single PhD thesis from 2007 and nowhere else; it has not been taken up by the rest of the cryptographic community. This compares to literally thousands of papers on PRPs, a fundamental concept taught in every cryptography course. Are "unpredictable permutations" sufficiently notable to mention at all, let alone with the same weight as PRPs? This is only likely to mislead newcomers looking for a description of PRPs. --Daira Hopwood ⚥ (talk) 16:23, 8 March 2021 (UTC)[reply]
