Effective CISSP Questions

Which of the following is the most fundamental cryptographic primitive used by WPA3 in a wireless network? (Wentz QOTD)
A. Rijndael
B. Galois/Counter Mode
C. Counter Mode CBC-MAC Protocol (CCMP)
D. Advanced Encryption Standard (AES)

Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.

My suggested answer is A. Rijndael.

Wentz’s book, The Effective CISSP: Security and Risk Management, helps CISSP and CISM aspirants build a solid conceptual security model. It is a tutorial for information security and a supplement to the official study guides for the CISSP and CISM exams and an informative reference for security professionals.

Cryptographic Primitives

Cryptographic primitives are well-established, low-level cryptographic algorithms that are frequently used to build cryptographic protocols for computer security systems.

WPA3 uses AES as the cipher to encrypt messages (in GCM mode) and calculate message authentication code (in Galois MAC). AES standardizes the usage of the Rijndael algorithm. As a result, Rijndael is the most fundamental cryptographic primitive used by WPA3.
