Abstract
Side-channel attacks target primarily the physical implementation of a computer system. Unlike traditional computer systems, embedded systems are particularly vulnerable to this class of attacks, because they often operate in untrusted environments and due to their accessibility. An example of a side channel attack is a cold boot attack on DRAM memories. In a cold boot attack, an attacker aims to obtain a memory dump after a cold restart in order to read out sensitive information like cryptographic keys. Ptolemy II is a powerful framework, where multiple models of computation can be explored for actor-based design of embedded systems. Since computation relies on a large extent of the computer architecture that is used for execution, the Ptolemy II framework can significantly benefit from the integration of architecture models. In this poster, we propose a tool integration approach of the gem5 computer architecture simulator and Ptolemy II. The gem5 simulator generates information such as execution time and memory access for a specific computer architecture. We use this information to build a more fine-grained system model in Ptolemy II. We demonstrate the integration of both tools by modeling power and the temperature of a DRAM in a computer architecture as preliminary steps to model DRAM side-channel attacks and possible countermeasures.
