Does ccmp - wpa2 works on 802.11bg?

Yes, CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) is a security protocol used with WPA2 (Wi-Fi Protected Access II), and it is compatible with 802.11b/g wireless standards. Both WPA2 and CCMP can work on these standards, providing enhanced security features over the older WEP (Wired Equivalent Privacy) protocol. However, it is essential to ensure that the hardware and firmware support WPA2 for proper functionality.
