| Abstract: | Security issues appearing in one or another form become a requirement for an increasing number of embedded systems. Those systems, which will be ubiquitously used to capture, store, manipulate, or access data of a sensitive nature, pose several unique and urgent challenges. Taking one of typical system vulnerability buffer o- verflow as an example, we attempt to provide a unified view of embedded system security by first analyzing the principle of this attack. We then propose two hardware based protection methods and show how these mechanisms have been implemented in hardware level. The numerical result of simulation demonstrates their feasibility and efficiency. |
