Method And System For Anonymous Operation Of A Mobile Node |
摘要 |
A mobile node and its home system generate synchronized time-based codes at periodic time intervals. 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.
