  1. Encryption, Privacy, & Authentication Chris R Chris H Mindy C

  2. 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

  6. Authentication • WPA Personal AES Key

  7. 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

  8. Cracking

  9. WEP • WEP-64 • Packets • Took approximately 40 Min • 530,000 packets • 416,856 IV’s • Cracking • Took Approximately 1 second • Key: test

  10. WEP • WEP-128 • 450,000 IV’s • Failed • 1.5 Million Packets • 1 Million IV’s • Success!

  11. WPA • WPA • Handshake • Only one necessary • De-authentication • Aireplay-ng • Failed • Manually forced reconnect • Passphrase • 11 Characters • Dictionary Attack • Success!

  12. WPA2 • WPA 2 • Handshake • Only one needed • De-authentication • Aireplay-ng • Failed • Manually Forced reconnect • Passphrase • 12 Letters • Dictionary Attack • Success!
