Kennell and Jamieson recently introduced the Genuinity system for authenticating trusted software on a remote machine without using trusted hardware. Genuinity relies on machine-specific computations, incorporating side effects that cannot be simulated quickly. The system is vulnerable to a novel attack, which we call a substitution attack. We implement a successful attack on Genuinity, and further argue this class of schemes are not only impractical but unlikely to succeed without trusted hardware.
