David Houlton (Independent Network Security Researcher)
Presentation Title: Cracking the GSM A5/1 Encryption in Seconds
Presentation Details:
This talk is about GSM security. We will explain the security, technology and protocols of a GSM network. We will further present a solution to build a GSM scanner for 900 USD. The second part of the talk reveals a practical solution to crack the GSM encryption A5/1. We are hoping to give a practical demonstration of decrypting a GSM conversation.
