Wireless privacy and integrity methods — Quiz

Wireless privacy and integrity methods

1. What was the primary design constraint that led to the creation of TKIP and the Michael MIC? (Choose one answer) a) The need for faster data throughput than WEP could provide b) The requirement to replace WEP without requiring new hardware c) A government mandate to use stronger encryption algorithms d) The desire to simplify the user configuration process

2. How does a Keyed Integrity Check (Message Authentication Code) fundamentally differ from an Unkeyed Integrity Check (Cryptographic Hash) in terms of security? (Choose one answer) a) A MAC produces a longer output value, making it harder to break b) A MAC uses a secret key, preventing an attacker from forging a valid integrity value c) A cryptographic hash is faster to compute, making it better for real-time communications d) A cryptographic hash provides confidentiality in addition to integrity

3. Which WPA3 security component is responsible for providing both encryption and integrity, representing a significant advancement over the separate mechanisms used in WPA? (Choose one answer) a) TKIP sequence counter b) AES-GCMP c) The Michael MIC d) The Pre-Shared Key (PSK)

4. Why were TKIP and the Michael MIC ultimately deprecated in the 802.11 standard? (Choose one answer) a) They were too computationally expensive for modern access points b) They were incompatible with the newer 5 GHz frequency band c) They were found to have vulnerabilities and were no longer considered secure d) They required licensing fees that made them prohibitively expensive

5. What is the primary cryptographic algorithm that provides confidentiality in both the AES-CCMP (WPA2) and AES-GCMP (WPA3) protocols? (Choose one answer) a) The RC4 stream cipher b) The CBC-MAC integrity check c) The Advanced Encryption Standard (AES) in counter mode d) The Galois Message Authentication Code (GMAC)
