The policy information point within each network endpoint node stores a distributed ledger including one or more client policies that must be satisfied to access the network, and a smart contract including a set of predefined rules defining network access behaviors and actions. Upon receiving a network access request from a client device outside of the network, the policy decision point within each network endpoint node executes the smart contract to determine whether the client device should be granted access, denied access or have restricted access to the network, and executes consensus algorithm to select one of the network endpoint nodes to be a policy decision point leader."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for distributed network access control","description":"Various embodiments of network access control (NAC) systems and methods are provided herein to control access to a network comprising a plurality of network endpoint nodes, where each network endpoint","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11496518","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.
