Title: John Kenneth Stacy: Innovator in Network Security
Introduction
John Kenneth Stacy is a notable inventor based in Cary, NC (US), recognized for his contributions to network security technologies. With a total of 11 patents, he has made significant advancements in the field, particularly in the area of denial-of-service attack prevention.
Latest Patents
One of his latest patents is titled "Hardware filtering support for denial-of-service attacks." This invention provides a system and method for automatically identifying and removing malicious data packets, such as denial-of-service (DoS) packets, in an intermediate network node. By doing so, it prevents the CPU's processing bandwidth from being consumed by these malicious packets, allowing for more efficient processing of non-malicious packets. Unlike traditional techniques, this invention can identify complex encapsulations of malicious packets that are typically difficult to detect.
Another significant patent is the "Header range check hash circuit." This technique efficiently searches a hash table containing multiple ranges, performing fewer searches to locate the desired ranges. The hash table is designed so that each entry is linked to a different list, which stores signature information and range values. This innovative approach results in shorter linked lists, enabling faster and more efficient range searches, particularly in flow-based processing within network nodes like routers.
Career Highlights
Throughout his career, John Kenneth Stacy has worked with prominent companies such as IBM and Cisco Technology, Inc. His experience in these leading technology firms has allowed him to develop and refine his innovative ideas in network security.
