3. WPA2 Process.

4. WPA2 Authentication.

5. WPA2 Encryption.

6. WPA2 Pros and Cons.

8. It uses the RC4 encryption protocol to secure the data.

11. It uses the RC4 encryption protocol to secure the data.

12. It uses MIC (Message Integrity Code) and frame counter to verify integrity of the data.

13. It uses EAP(Extended Authentication Protocol) to authenticate the clients.

17. The Personal mode uses a PSK (Pre-Shared Key) and doesn't require a separate authentication of users.

21. Phase (2):Generate the master key.

22. Phase (3):Creating temporary keys in regular manner.

26. The security protocols for unicast traffic (CCMP, TKIP etc.) – the pairwise cipher suite.

34. The authentication in the WPA2 Personal mode does not require having an authentication server.

35. WPA2 Enterprise mode consists of the following components:

36. Supplicant (client).

37. Authenticator (access point).

39. One for service “only open to allow the successful authentications”.

42. The 4-Way Handshake is initiated by the access point and it performs many tasks like:

43. Verify that the client knows about the PMK.

44. Generate a PTK.

45. Install encryption and integrity keys.

46. Encrypt transport of the GTK.

47. Make sure that the cipher suite the selection.

51. The AES uses the Counter-Mode/CBC-MAC Protocol (CCMP).

59. Man-in-the-middle.

60. Authentication forging.

61. Replay.

62. Key collision.

63. Weak keys.

64. Packet forging.

66. Allow the client to reconnect to the access points which he has recently been connected to without needing to re-authenticate because of the PMK caching feature.

68. It supports strong encryption and authentication for both infrastructure and an ad-hoc network; in contrast WPA just supports the infrastructure networks.

70. RF jamming.

71. Data flooding.

72. Access points failure.

74. It is vulnerable for the DoS attack.

76. Good planning for the Wi-Fi coverage will improve the availability and reduce the risk of RF jamming attacks.
