Patent number: 9883224Abstract: To allow a user to temporarily move access to premium content to another location, e.g. outside the vicinity of the home, while adequately protecting the rights of a broadcast content provider, the various examples implement a transfer of an object for an identified right of content usage between premium content reproduction devices and a mobile device. The mobile device enables such transfer to support viewing of the premium content by a user outside of the user's home.Type: GrantFiled: December 10, 2013Date of Patent: January 30, 2018Assignee: Cellco PartnershipInventors: Kevin Donnellan, Quentin N. Robinson, Te-Sheng Lin, Muxiang Zhang, Young Rak Choi, Samuel Olushermimo Akiwumi-Assani

Patent number: 9032205Abstract: Embodiments of the invention may be used to provide an authentication and key agreement protocol that is more robust against base station, replay and other attacks compared to previously known systems. The nonce-based authentication and key agreement protocol provides security against such attacks while avoiding the problems that arise in systems that use sequence number counters on the home environment and mobile station-sides. In an embodiment, a nonce that is transmitted from the user to the home environment through the serving network, as well as subsequent values for the nonce that are derived from the initial nonce, are used as indices for authentication vectors.Type: GrantFiled: July 7, 2009Date of Patent: May 12, 2015Assignee: Verizon Patent and Licensing Inc.Inventor: Muxiang Zhang

Patent number: 8438393Abstract: A method is provided for use in secure electronic communication. The method may include obtaining a password shared with an intended key exchange entity and sending a key exchange request including a first value to the intended key exchange entity. The method may also include receiving a key exchange reply including a permutation of a first quadratic residue of the first value, and calculating a second quadratic residue of the first value based on the key exchange reply. Further, the method may also include determining a second value shared with the key exchange entity based on the first quadratic residue and the second quadratic residue.Type: GrantFiled: March 4, 2011Date of Patent: May 7, 2013Assignee: Verizon Data Services LLCInventor: Muxiang Zhang

Patent number: 8347075Abstract: The present invention provides methods to mitigate the problems associated with MAC address spoofing and denial of service attacks in an FTTH network system. The MAC address spoofing attack may occur when a computer hacker configures his computer to change the MAC address of a data signal to deceive the receiver of the signal's source address. The denial of service may occur when a computer hacker floods a file server with data packets. The present invention mitigates these attacks by modifying the software of certain components of the FTTH network system to enable the components to insert virtual MAC addresses, tags and codes into the data packets that identify a component of the communication related to the address of the source computer.Type: GrantFiled: November 1, 2002Date of Patent: January 1, 2013Assignee: Verizon Laboratories Inc.Inventor: Muxiang Zhang

Patent number: 8345713Abstract: Methods and apparatus for improved scrambling and/or descrambling of packets in a communications network are described, e.g., improved scrambling/descrambling of MPEG-2 transport stream packets over an Internet Protocol network. Advance Encryption Standard (AES) under cipher block chaining is utilized in scrambling some transport stream packets. Methods and apparatus for computing an initialization vector or vectors used by the AES are also described. The initialization vector can be set to either a constant or a programmable random number. Scrambling methods and apparatus directed to scrambling solitary termination blocks with a reduced size packet payload e.g., less than 128 bits in an MPEG-2 transport stream packet, are also described. Various features are useful for and can be implemented in set-top boxes and IPTV scramblers in the headsets.Type: GrantFiled: October 25, 2006Date of Patent: January 1, 2013Assignee: Verizon Patent and Licensing Inc.Inventor: Muxiang Zhang

Patent number: 6879689Abstract: Methods and systems are provided for processing information. In one embodiment, there is provided a method, providing a frame key based on a master key and a frame number of a frame of information to a keystream generator as an initial fill for one or more registers of the keystream generator such that the initial fill establishes a state for the one or more registers of the keystream generator; and generating, at the keystream generator, a keystream sequence based on the state established by the initial fill, wherein the keystream sequence includes a modulo-2 sum of a lagged-Fibonacci sequence and a pseudo-random sequence produced by a filter generator.Type: GrantFiled: May 9, 2001Date of Patent: April 12, 2005Assignees: Verizon Laboratories Inc., Genuity, Inc.Inventors: Christopher Paul Carroll, Muxiang Zhang, Agnes Chan
