HyperIO: A Hypervisor-Based Framework for Secure IO

Featured Application: We present a Firefox extension acting as a trust indicator and a clipboard encryptor. The framework can also be used for other means such as storing passwords, secure access to crypto wallet, etc. Malware often attempts to steal input and output through human interface devices to obtain confidential information. We propose to use a thin hypervisor, called “HyperIO”, to realize a secure path between input and output devices using a partial implementation of device drivers. We apply our approach using two security systems built on HyperIO: FireSafe and ClipCrypt. FireSafe is a web browser extension which allows a remote web server to display and receive sensitive user information securely. ClipCrypt enables the user to securely enter and view their confidential information in commodity Windows applications.
