Each time-based code is valid for a predetermined time period. To facilitate anonymous operation when roaming, the mobile node identifies itself with a coded identifier instead of a public identifier. The coded identifier used at a given time includes the time-based code that is valid for that given time. To authenticate the mobile node, a serving system receives authentication information from the mobile node and forwards the authentication information to a home system. The authentication information includes the current time-based code and a timestamp. The home system identifies the mobile node from the current time-based code and the timestamp. The home system then uses the authentication information to authenticate the mobile node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for anonymous operation of a mobile node","description":"A mobile node and its home system generate synchronized time-based codes at periodic time intervals.
