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

Project Overview Two Components Evaluation/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)

SecurityAuthentication Time (Seconds) WEP WEP WPA Personal TKIP1.013 WPA Personal AES1.012 WPA2 TKIP/AES1.013 Authentication Comparison Between Authentication Periods

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

Cracking

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

WEP WEP ,000 IV’s Failed 1.5 Million Packets 1 Million IV’s Success!

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

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