You're in luck! Several years ago I was thinking about extending some aspects of WPA and wanted to test using my phone. It seemed that you need to add these as flags, so that made me dive in the Android source code, specifically
Then @schroeder posted a link to your question on a private chat room, and it instantly rang a bell. I went back to the
wpa_supplicant source code and traced it back a bit until I found references for the flags. If you look at line 89 there, you can see that the scan results entries ordered in the same exact order they appear in scan results console, so from there you can see that they're "flags" and you can go back in the source code to where they're declared.
Anyway, these are called '802.11 Access Point security flags'. Here's the reference list of the flags used in Android. For instance,
[SEC80] would be
NM_802_11_AP_SEC_GROUP_CCMP. I'm not really sure what
[SECD00], but the 802.11-2012 specifications might give you some hints.
