Cryptography Questions and Answers
What two encryption methods are commonly used with WPA2 - answer AES and
TKIP
AES (Advanced Encryption Standard) - answer AES stands for Advanced Encryption
Standard, a widely used symmetric encryption algorithm. It operates on fixed-size data
blocks and supports key lengths of 128, 192, or 256 bits. Known for its security and
efficiency, AES is a standard choice for data encryption.
AES-CCMP - answer AES-CCMP is a security protocol in Wi-Fi networks, part of
WPA2 and WPA3. It stands for Advanced Encryption Standard with Counter Mode
Cipher Block Chaining Message Authentication Code Protocol. It ensures secure
transmission by providing encryption, integrity, and authentication for wireless data.
What encryption does WEP use? - answer RC4
RC4 - answer RC4, or Rivest Cipher 4, is a symmetric stream cipher created by Ron
Rivest. It generates a pseudorandom stream of bits that is combined with plaintext using
bitwise XOR. Although widely used in the past, RC4 is now considered insecure due to
vulnerabilities, and its usage is discouraged.
EAP - answer EAP, or Extensible Authentication Protocol, is an authentication
framework used in wireless networks and point-to-point connections. It allows for
various authentication methods in communication sessions, providing a standardized
approach. Commonly used for securing Wi-Fi networks and other protocols.
EAP-TLS (Transport Layer Security) - answer EAP-TLS, or Extensible Authentication
Protocol with Transport Layer Security, is an EAP method known for secure
authentication. It utilizes TLS for key exchange and involves digital certificates for server
and client authentication. Widely used in enterprise environments due to its strong
security features.
EAP-PEAP (Protected Extensible Authentication Protocol): - answer EAP-PEAP, or
Protected Extensible Authentication Protocol, is an EAP method that secures
authentication by encapsulating EAP within a TLS tunnel. Widely used in Wi-Fi
networks, it strikes a balance between security and compatibility.
EAP-TTLS (Tunneled Transport Layer Security): - answer Tunneled Transport Layer
Security
establishes a secure tunnel for authentication, akin to EAP-PEAP.
, It involves a two-phase process: first, a TLS tunnel is created, and then inner
authentication methods (e.g., EAP-MSCHAPv2) are used for user authentication.
Widely used in Wi-Fi networks, EAP-TTLS provides flexibility by supporting various
inner authentication methods.
EAP-MSCHAPv2 (Microsoft Challenge Handshake Authentication Protocol version 2): -
answer used in Microsoft environments.
It enables password-based authentication through challenge-response exchanges.
However, it has known vulnerabilities, and more secure alternatives like EAP-TLS are
recommended for enhanced security.
EAP-SIM (Subscriber Identity Module): - answer used in mobile networks.
SIM card in mobile devices for secure authentication, avoiding the transmission of
sensitive information over the air.
EAP-AKA (Authentication and Key Agreement): - answer utilized in 3G and 4G
mobile networks.
It utilizes the SIM card for authentication, similar to EAP-SIM.
ensures secure user authentication in wireless communication,.
an encryption protocol used in Wi-Fi networks for secure data transmission.
based on AES and is part of WPA2/WPA3.
