Latest Patents

One of Simon's latest patents is titled "Provable geo-location." This invention involves a geo-location provider station that signs geo-location data along with a previous signature provided by a mobile device. The mobile device then uses this new signature when requesting a signature from another geo-location provider station. Additionally, the mobile device stores the geo-location data and the signatures provided by various geo-location provider stations. This stored geo-location data can be verified upon request using the stored signature data.

Another significant patent is "Mitigation of stack corruption exploits." This invention describes a stack protection engine designed to prevent or reduce the impact of stack corruption attacks. The stack protection engine operates transparently to user-space processes. After a call to a subroutine from a parent routine, the engine encodes the return address on the stack using an exclusive or cipher and a key selected from a key array. When the subroutine returns control to the main routine, the engine decodes the address and returns control. If a stack corruption attack occurs, the malicious return address is not properly encoded, causing the program to crash instead of returning control to the malicious code.
