If you look at all of the existing tags, they pretty much each represent a single, objectively definable concept that appears in the subject of cryptography itself. Katz-Lindell is not an algorithm, protocol, etc, but the name of a book (or rather the authors names).
It would be a clear outlier when examined alongside the other tags.
This may qualify as a "meta tag", which are generally discouraged.

If the tag can’t work as the only tag on a question, it’s probably a meta-tag. Every tag you use should be able to work, more or less, as the only tag on a question...
It fails the meta tag test
It fails the test provided in the quote above. You can't define the content of a question with a single
Katz-Lindell tag, but you can do so with a
PRG tag (or similar).
This same argument applies for the generalized form of a
I think it's not a good fit.
