# The security tag

The seems rather redundant - isn't almost all cryptography related to security?

• I don't think queuing edits(as a low rep user) just to remove this tag is a good idea. Jul 27 '12 at 9:40
• @CodesInChaos OK. Jul 27 '12 at 10:15
• @Inkbug: In general, when you are editing a post (question or answer), try to fix as much issues as possible at once. If someone has to look at your edit to approve it, make it count. Jul 27 '12 at 14:53
• @PaŭloEbermann Ok. Thanks for the tip! Jul 29 '12 at 6:41

The problem of this tag is that it is used quite unspecific. In the wider sense, almost everything on this site relates to security, thus it is useless here.

In a less wide sense, one often speaks of a $n$-bit security of some primitive or protocol, meaning that an attacker needs at least $2^n$ steps of work to break it. It could be useful this way (and in the past, I left out these usages when removing the tag from other questions), but it would need a good tag wiki for this, as well as some discipline (or regular supervision) to make sure it is not used when not appropriate.

Could we find a better tag name for this second (maybe valid) usecase, so we can ban the general one?

• Perhaps [security-level] or [work-factor] Jul 28 '12 at 7:52
• I suggest concrete-security. @CodesinChaos's suggestions are reasonable too.

• @CodesInChaos: Did you find/use a replacement tag for the valid use cases, or did you (and others) just remove the existing ones? (Sorry, I didn't follow the progress too close.) Sep 6 '12 at 17:13
• @PaŭloEbermann I don't remember running into any questions where it was useful, but perhaps I missed some. Sep 6 '12 at 18:06

This tag looks useless to me. I've started to detag a few of the questions which have this tag.
