A client receives the puzzle, generates a solution for the puzzle, and sends a network request to the server along with the solution of the puzzle. The server verifies the puzzle solution. If the puzzle solution is valid and received within a designated validity time period, then the server processes the request of the client. The server generates the puzzle and transmits the puzzle to the client before the client generates a request for services from the server."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for mitigation of denial of service attacks in networked computing systems","description":"In a method of network communication that mitigates denial of service attacks, a server broadcasts cryptographic puzzles with certain time intervals, where each puzzle is only valid for the given time","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9614868","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
