    摘要: A method and apparatus for secure direct link communication between multiple wireless transmit/receive units (WTRUs) are disclosed. The WTRUs may exchange nonces that are used for generating a common nonce. Group identification information may be generated from at least the common nonce and is forwarded to an authentication server. The authentication server may generate a master key from the group identification information to match WTRUs as part of a key agreement group. The common nonce may be a session key and be refreshed during communication with the second WTRU. A group key encryption key (GKEK) and a group key confirmation key (GKCK) may also be generated based on the common nonce and used to encrypt and sign the master key so that base stations do not have access to the master key. A first WTRU may generate a group direct link temporal key (GDLTK) for communicating with the second WTRU.

    摘要: Systems, methods, and instrumentalities are disclosed for defining a network specialization mechanism that enables a better alignment between end users' usage profiles and their access networks. Conteni specialization of networks may be implemented as a preference o a particular SCN or network in terms of content. Such a network may, for example, cache in priority preferred content, provide preferential quality of service (QoS), or limit access to non-preferred content. A network may advertise its preference or content specialization to end users (e.g., so that end users can decide to attach to SCNs or networks with compatible preferences) and to other content networks (e.g., to influence content routing decisions or to negotiate partitioning of the specialization space). Such content specialization may apply to physical or virtual networks.
