Project Overview

Two ComponentsEvaluation/Authentication

• Setup of each wireless security• Comparison between authentication• Evaluation of encryptions

Cracking• Ease of breaking• Methods used

Authentication

WEP64

WEP128

Authentication

WPA (TKIP, AES) / WPA2 (TKIP/AES)

Security Authentication Time (Seconds)

WEP64 .0047

WEP128 .0049

WPA Personal TKIP 1.013

WPA Personal AES 1.012

WPA2 TKIP/AES 1.013

Authentication

Comparison Between Authentication Periods

Authentication

WPA Personal AES Key

WEP/WPA Notes

WEP key management harder to setup from a user standpointWEP128 Key:

7A08BC60865F25EA684F4801FA

WPA has greater connection overhead / issuesSwitching between WPA and other

securities can cause problems in Windows

Cracking

WEP WEP-64
