Latest Patents

One of his latest patents is titled "Out-of-band spy detection and prevention for portable wireless systems." This invention employs an 'out-of-band' mechanism to remove the physical controls for activating input peripherals from a portable device operating system. Instead, these controls are managed by a separate peripheral control domain, which is isolated from the operating system domain through machine virtualization and isolation technology. Notably, no additional hardware is required for this system. An adjunct I/O virtualization mechanism is also included to abstract the guarded input peripheral interfaces. This ensures that any attempts to activate these peripherals from within the operating system are automatically redirected to the peripheral control domain. The peripheral control domain then conducts a policy-driven decision process to either allow, disallow, or request manual authorization for access attempts. This innovative approach ensures that security-critical operations are immune to vulnerabilities present in the portable operating system.

Another significant patent involves executing a remote control command to activate one or more peripherals of a mobile device within a peripheral control domain. In this scenario, virtualization mechanisms that defend against spying can also be exploited by attackers to execute spying attacks more effectively. Attack methods may utilize these virtualization mechanisms to activate input peripherals without the user's knowledge or authorization. A virtualized network interface may be employed, routing all network traffic through a remote control component within the peripheral control domain. This component allows an attacker to communicate remotely with the portable device and send peripheral activation commands, all while bypassing the user's awareness and the general-purpose operating system.
