Title: Innovations of Rahuldeva Ghosh
Introduction
Rahuldeva Ghosh is a prominent inventor based in Portland, OR (US), known for his significant contributions to technology and security. He holds a total of 17 patents, showcasing his expertise in developing innovative solutions to complex problems.
Latest Patents
One of his latest patents focuses on side-channel exploit detection. This invention is directed towards systems and methods for detecting side-channel exploit attacks, such as Spectre and Meltdown. The performance monitoring circuitry includes first counter circuitry to monitor CPU cache misses and second counter circuitry to monitor DTLB load misses. Upon detecting an excessive number of cache misses and/or load misses, the performance monitoring circuitry transfers the first and second counter circuitry data to control circuitry. The control circuitry determines a CPU cache miss to DTLB load miss ratio for each of a plurality of temporal intervals. It identifies, determines, and/or detects a pattern or trend in the CPU cache miss to DTLB load miss ratio. Upon detecting a deviation from the identified pattern or trend indicative of a potential side-channel exploit attack, the control circuitry generates an output to alert a system user or system administrator.
Another notable patent involves a secure performance monitoring unit of a processor. This invention includes one or more performance monitoring counters and a secure group manager. The secure group manager is configured to receive a request to create a secure counter group from a software process being executed by a processor. It determines the availability of the counters, creates the secure counter group, assigns the counters, and saves a public key of the software process. The secure group manager also verifies the configuration using the public key and begins sampling of the counters once verified.
