Details

nas is the Broadcom WLAN Network Authentication Server. It is the WPA authenticator and is started by wlmngr2.
There's an alias nas4not which calls the same binary, just intended for WDS link authentication.

The source of nas could not be located on the GPL-Browser but there's some older source on Github.
Excerpt from its README:

NAS is a minimal VxWorks and Linux compatible Network Authentication
Server that implements 802.1X port authentication (RADIUS only) and
Wi-Fi Protected Access (WPA) for 802.11 networks (Broadcom drivers only).

The FRITZ!OS build of nas does not provide any help function, but the optarg string is
B:g:h:i:I:k:r:K:l:m:N:p:s:t:v:w:d:ADSF. Collected from the nas_wksp.c source linked above:

Usage: nas [options]

  -i <interface>       Wireless interface name
  -A                   NAS in Authenticator mode
  -S                   NAS in Supplicant mode
  -g <interval>        WPA GTK rotation interval (ms)
  -h <address>         RADIUS server IP address
  -p <port>            RADIUS server UDP port
  -k <secret>          WPA pre-shared key
  -r <secret>          RADIUS server secret
  -m <authentication>  Authentication protocol - WPA | WPA_PSK | RADIUS | WPA2 | WPA2_PSK
  -s <SSID>            Service Set Identity
  -w <encryption>      Crypto algorithm - WEP | TKIP | AES
  -I <index>           WEP key index - 2 | 3
  -K <key>             WEP key
  -t <duration>        Radius Session timeout/PMK Caching duration (ms)
  -N <NasID>           NAS id
  -v <debug>           Verbose mode - 0:off | 1:console
  -D                   NAS in WDS mode
  -d                   Disable WPA2 preauth

The -i <interface> option must be present before any other per interface options 
to specify the wireless interface.
