Abstract: In one embodiment, a method for establishing Quality of Service (QoS) in a home network is provided. The method comprises: receiving a request for bandwidth in a virtual private network (VPN); receiving a traffic specification of an application on a control point retrieving a traffic policy; retrieving path characteristics of the VPN; and reserving resources in the VPN based on the path characteristics, the traffic policy, and the traffic specification.

Abstract: Methods and systems of rendering content on a device having a native digital rights management (DRM) system are described. A device, such as an end-user device capable of executing or playing content, acquires content in a common content format file having standardized locations for specific types of data. A generic digital rights token associated with the content is obtained by utilizing one of the standardized locations in the content format file, where the rights token contains information sufficient to allow retrieval of the rights associated with the content. Utilizing data in another of the standardized locations, it is then determined whether the device is registered in a domain. A license server directory may be accessed utilizing data in another of the standardized locations in the common content format file and a domain identifier, a device identifier, or both are transmitted to the license server directory.

Abstract: A secure authentication channel (SAC) between two nodes in a communication network is created by the nodes themselves using mutual authentication. The network has two nodes, a coordinating entity, two PKI-based SACs, and one non-PKI SAC which is created by the two nodes and is for use by the nodes. The coordinating entity generates a master key which is transmitted to two nodes via a PKI-based SAC established between the coordinating entity and each of the two nodes. One node uses the master key to generate a first random number and the second node uses the key to generate a second random number. The second node also has an encrypted third random number. The network also has a third SAC, which is not solely based on PKI, between the first node and the second node and is created when the two nodes have authenticated each other. The mutual authentication process occurs without the intervention of the coordinating entity.

Abstract: In mobile IP networks, when a mobile node (MN) 101 moves from one cell to another, handover occurs. The result of the handover is that the MN 101 connects to the network through a new access router (AR) 162. The handover may occur between access routers of the same or different administrative domains. In all cases, the information related to the MN 101 has to be transferred from the old AR 185 to the new AR 162 in order to minimize the effect of the change of access routers.

Abstract: A system and method for transmitting protected real-time content from one user to another is described. In a first aspect, a user sends a Rights Object to another user. In a second aspect, a user sends a Rights Object to another user via an intermediate server for a multiparty communication. In this second aspect, the users may be able to switch between designated Rights Objects as needed.

Abstract: A system and method of providing content protection for OMA Broadcast smartcard profiles. When an electronic device has a content item for encryption, the device generates a random number. The electronic device then transmits a content encryption key request message, including the random number and a service encryption key identifier, to a smartcard, which then responds with a a content encryption key response message. The content encryption key response message includes the random number and a content encryption key. The electronic device can then use the content encryption key to manage the encryption of the content item. The electronic device stores random number, service key identifier and encrypted content item into a certain file format. The electronic device sends again content encryption key request at the time of rendering.

Abstract: An approach is provided for providing service keys in multiple broadcast networks. A message including a group of keys is generated for providing secure communication over a first broadcast network and a second broadcast network. A message is transmitted to a terminal within the first broadcast network and a terminal within the second broadcast network. An encrypted service key is broadcast to the terminals, wherein the encrypted service key is decrypted using a portion of the group of keys.

Abstract: A technique for selecting the offset between data bursts and their respective control packets in an optical burst switching arrangement includes: randomly generating a plurality of tokens; receiving a plurality of sequentially generated data bursts; and receiving a plurality of control packets, each control packet corresponding to a respective one of the plurality of data bursts. One of the plurality of control packets is first outputted and its corresponding respective data burst is then outputted at a time corresponding to the generation of the first of the plurality of tokens which occurs at a time in which no data burst is being outputted, the outputting of the data burst being offset from the output of its corresponding respective control packet by a time period. The average rate at which the plurality of data bursts are outputted may be equal to the reciprocal of the mean of the probability distribution used to generate the plurality of tokens.

Abstract: An apparatus, software modem, and method for a data communications device, such as a modem (100, 101), to determine a symbol rate and carrier frequency, from a received probe signal, for optimizing a bit rate for data transmission and reception. The various embodiments utilizing a processor (108) or a digital signal processor (106) receive a probe signal, which also typically contains noise and other distortions, particularly envelope delay distortion. The various method and apparatus embodiments then determine a variance of the envelope delay distortion, either directly or indirectly as a correlate of attenuation distortion or as a correlate of a selected transmit pre-emphasis filter specified under the ITU V.34 protocol. The variance of the envelope delay distortion is then utilized to eliminate or disable certain symbol rates and corresponding carrier frequencies in the determination of an optimal symbol rate and carrier frequency for data transmission and reception.
