Abstract
Systems, methods and instrumentalities are described herein that provide security and/or privacy support for wireless transmit receive units (WTRUs) communicating via a WTRU to WTRU relay. A source WTRU may obtain a new IP address from a relay WTRU via a link identifier update request. The source WTRU may indicate to the relay WTRU which one or more target WTRUs are to be informed of the new IP address. The source WTRU may indicate to the relay WTRU whether the target WTRU's ID(s) should be changed. The relay WTRU may send the source WTRU's new IP address to authorized target WTRUs. The source, relay, and target WTRU may use tokens to grant or receive authorizations for sharing each other's IP addresses.
