A Note on the Relay Attacks on e-passports: The Case of Czech e-passports.

摘要: The threat of relay attacks on authentication protocols is often well recognized, especially for contactless applications like RFID chips. It is, therefore, a bit surprising to meet an implementation that actually encourages rather than eliminates these attacks. We present our experimental observations concerning Czech e-passports. These show clearly inherent weakness rooted in lower layers ISO 14443. As the behavior unavoidable, it induces question whether e- passport should not have used dierent communication protocol or scheme.
