Abstract

Techniques are presented herein for improved network security. Traversal Using Relays around Network Address Translation (NAT) (TURN) can be used to solve the privacy problem by not exposing the host/server-reflexive candidate addresses to the remote peer for privacy reasons. Relayed candidates are advertised and host/server-reflexive candidates are removed from the offer/answer by the network when there could be potential privacy leakage problem. This gives the user an option to select privacy, which internally translates to advertising relayed candidates. The TURN server will rotate the relayed addresses frequently among the clients. If TURN server is IPv6-aware then it will use IPv6 privacy addresses for relayed addresses so that these addresses are frequently changed.
