Latest Patents

One of his latest patents is titled "Integrity Protected Access Control Mechanisms." This invention details embodiments that allow for integrity-protected access control, providing defense against deterministic software attacks. It specifically addresses software attacks such as rowhammer attacks, which target the TD bit itself. By utilizing cryptographic integrity, the data is protected by the TD-bit alone, effectively reducing software to performing only non-deterministic attacks. This innovation ensures that all deterministic attacks are defended against. Additionally, the integrity-protected access control bits are safeguarded against simple hardware attacks, where an adversary with physical access to the machine can manipulate TD bits to gain unauthorized access to ciphertext in software, thereby compromising confidentiality.

Another notable patent is the "Method and Device for Achieving Optical Alignment Using Laser Pulses." This invention describes a process where an optical element is aligned on a flexure by applying multiple laser pulses. Additional laser pulses are applied until the optical element is properly aligned, showcasing a novel approach to precision in optical engineering.
