Question

what encryption method does the ieee 802.11-2012 standard mandate for robust security network associations and what method is optional?

Answer 1

The IEEE 802.11-2012 standard mandates CCMP as the encryption method for robust security network associations, using the AES algorithm, while TKIP is optional for backward compatibility.

Step-by-step explanation:

The IEEE 802.11-2012 standard specifies the encryption methods that must be used to ensure secure associations in robust security networks. According to this standard, the mandatory encryption method for protecting the integrity of the packets is CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol), which uses AES (Advanced Encryption Standard) as the algorithm.

CCMP is an encryption protocol designed to provide strong security, replacing the older WEP (Wired Equivalent Privacy) which was found to be inadequate. Moreover, the use of TKIP (Temporal Key Integrity Protocol) is optional for backward compatibility with older devices that may not support the more robust CCMP protocol.
