METHOD FOR AUTHENTICATING DISCOVERY OF NEIGHBORHOOD IN THE IP NETWORK ENVIRONMENT FROM A CANDIDATE TERMINAL TO NETWORK ACCESS

摘要

The invention relates to a method for authenticating IP network neighborhood discovery of a terminal (T). A respective private cryptographic value (CVp, CVc) each value (CVc) of a daughter DNS zone that can be authenticated by the value (CVp) of the parent DNS zone is allocated (A) to each parent DNS zone. On a first access request from a terminal (T) to the IP network, a routing authorization registration procedure is started (B) from the access router (RA) of the child access area. issuing by the DNS server of the parent DNS zone a routing certificate (Cert (RA)) and launching (C) from the access router (RA) an authentication procedure of the routing certificate A (Cert (RA) ), depending on the private cryptographic value allocated to the parent DNS zone. Application to secure fixed or mobile terminal connections on the IP or Internet network.
