The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and
WPA3) and Wired Equivalent Privacy (WEP) doesn’t require that all fragments
of a frame are encrypted under the same key. An adversary can abuse this to
decrypt selected fragments when another device sends fragmented frames and
the WEP, CCMP, or GCMP encryption key is periodically renewed.
