Enforcing trust for execution-protection in modern environments
2016
The business world is exhibiting a growing dependency on computer systems, their operations and the databases they contain. Unfortunately, it also suffers from an ever growing recurrence of malicious software attacks. Malicious attack vectors are diverse and the computer-security industry is producing an abundance of behavioral-pattern detections to combat the phenomenon. Modern processors contain hardware virtualization capabilities that support implementation of hypervisors for the purpose of managing multiple Virtual-Machines (VMs) on a single computer platform. The facilities provided by hardware virtualization grant the hypervisor control of the hardware platform at an effective privil…
Preventing reverse engineering of native and managed programs
2015
One of the important aspects of protecting software from attack, theft of algorithms, or illegal software use is eliminating the possibility of performing reverse engineering. One common method used to deal with these issues is code obfuscation. However, it is proven to be ineffective. Code encryption is a much more effective means of defying reverse engineering, but it requires managing a cryptographic key available to none but the permissible users. The thesis presents a system for managing cryptographic keys in a protected environment and supporting execution of encrypted code. The system has strong security guarantees. In particular, the cryptographic keys are never stored on the target…
