Project Overview

• Two Components
• Evaluation/Authentication
• Setup of each wireless security
• Comparison between authentication
• Evaluation of encryptions
• Cracking
• Ease of breaking
• Methods used

3
Authentication

• WEP64
• WEP128

4
Authentication

• WPA (TKIP, AES) / WPA2 (TKIP/AES)

5
Authentication

• Comparison Between Authentication Periods

Security Authentication Time (Seconds)
WEP64 .0047
WEP128 .0049
WPA Personal TKIP 1.013
WPA Personal AES 1.012
WPA2 TKIP/AES 1.013
6
Authentication

• WPA Personal AES Key

WEP/WPA Notes

• WEP key management harder to setup from a user
  standpoint
• WEP128 Key
• 7A08BC60865F25EA684F4801FA
• WPA has greater connection overhead / issues
• Switching between WPA and other securities can
  cause problems in Windows
