Building a Trusted Path for Applications Using COTS Components
Abstract
Client computers are often a weak link in a technical network infrastructure. Increasing the security of client systems and applications against malicious software attacks increases the security of the network as a whole. Our work solves integrity and authenticity of input, confidentiality, integrity and authenticity of output. We present components to integrate a trusted path into an application to directly communicate with a user at a personal computer. This allows security sensitive parts of applications to continue operating while being attacked with malicious software in an event-driven system. Our approach uses widely employed COTS software - DirectX - and can be varied in design and implementation, hence making it more difficult to defeat with generic attack tools.
