Abstract
A hardware-based security module is used to protect an electronic device, especially a portable electronic device. The security module may determine either via timeout of a watchdog timer or via an explicit message to encrypt selected data on the electronic device. In addition, the electronic device may enter a limited function mode that only allows display of simplistic messages and supports network traffic with a recovery service. The recovery service may be able to use the network traffic to locate the electronic device. The security module may include a secure memory, a cryptographic function, a timer, and support for direct display of data on a monitor.
