Patent number: 7499548Abstract: A user terminal can be authenticated by an access point based on one message. In one embodiment, the present invention includes the access point receiving a message containing a shared secret encrypted with an access point public key, a user terminal certificate, and an authenticator string demonstrating possession by the user terminal of a user terminal private key. The access point can decrypt the shared secret using the private key of the access point paired with its private key. The access point can then authenticate the user terminal by checking the authenticator string using a user terminal public key included in the user terminal certificate to verify possession of the user terminal private key by the user terminal.Type: GrantFiled: June 24, 2003Date of Patent: March 3, 2009Assignee: Intel CorporationInventors: Branislav N. Meandzija, Mithat Can Dogan, Marc C. Goldburg, Christopher R. Uhlik

Patent number: 7487534Abstract: An application programming interface (API) for managing resources in a Digital Television (DTV) Receiver/Terminal. The API provides a uniform mechanism for gaining/controlling access to resources, managing multiple resources of the same type, and accessing the individual resource's management state and status. The resources may include, for example, a tuner, a modem, a database, a plug-in module, a cable, a software module, a network interface card, or a conditional access module. The resources are monitored and controlled either locally at the terminal, or remotely, e.g., from a head-end or an uplink. The API provides a resource package (40) for registering the available resources at the terminal, a resource state management package (30) for managing states of the resources, and a registry package (20) for storing objects that represent the resources. Resources of the same type are managed as a group.Type: GrantFiled: October 7, 1999Date of Patent: February 3, 2009Assignee: General Instrument CorporationInventors: Petr Peterka, Branislav N. Meandzija, Geetha Mangalore, Kurt Zaiser

Patent number: 7356029Abstract: A system and method of multiplexing data into an MPEG transport stream are described. In particular, an IP packet is examined to determine if it is a multicast IP packet. If so, the IP packet is repackaged into one or more MPEG packets for transmission in the MPEG transport stream.Type: GrantFiled: April 16, 2002Date of Patent: April 8, 2008Assignee: General Instrument CorporationInventors: Vicky B. Kaku, Branislav N. Meandzija, Randall Silagi

Patent number: 7302565Abstract: The certificate issued by a certificate authority used in authenticating a user terminal can be scrambled prior to being set to an access point. In one embodiment, the present invention includes a user terminal having a memory in which a user terminal certificate is stored. The user terminal also has a processor coupled to the memory to scramble the user terminal certificate using a shared secret to be known only by the user terminal and an access point of the wireless access network, and a transmitter coupled to the processor to send a message to the access point, the message including the scrambled user terminal certificate.Type: GrantFiled: June 24, 2003Date of Patent: November 27, 2007Assignee: Arraycomm LLCInventors: Branislav N. Meandzija, Mithat Can Dogan, Marc C. Goldburg

Patent number: 7266685Abstract: The time reference of a user terminal that is derived from an unauthenticated access point can be certified by a trusted entity according to the present invention. In one embodiment, the present invention includes a user terminal obtaining a time reference from an access point of a wireless access network. The user terminal then receives a digital certificate having a validity period from the access point, the certificate being issued by a certificate authority. In one embodiment, the user terminal requests certification of the time reference by a trusted entity, and receives the certification. Then the user terminal can validate the digital certificate.Type: GrantFiled: June 24, 2003Date of Patent: September 4, 2007Assignee: ArrayComm, LLCInventors: Branislav N.

Publication number: 20020085571Abstract: An enhanced Simple Network Management Protocol (SNMP) management system for telecommunications networks which efficiently provides many of the sophisticated management techniques enabled by Open Systems Interconnection (OSI), Common Management Information Protocol (CMIP) and Telecommunications Management Network (TMN) protocols, while maintaining the simplicity of SNMP. The enhanced SNMP defines a management state of each SNMP agent, define events which are to be reported from the agent to the management station, and provides a log for recording particular events and associated agent data vales when the events occur. The enhanced SNMP also provides the capability for an alarm, state change, and value change notification to be communicated from the SNMP agents to an SNMP management station when specific events occur at the agent.Type: ApplicationFiled: May 11, 1998Publication date: July 4, 2002Inventor: BRANISLAV N.

Patent number: 6170005Abstract: A system for providing synchronization and information exchange in a network such as a digital television broadcast network using a network management operations and control paradigm. A management entity component, such as a computer workstation operated at a control center, coordinates the actions of different agent components, such as hardware used at the headend or uplink site of a television network. The agent components are used to provide conditional access to a television signal by inserting conditional access data into the transmitted programming. Management information bases (MIBs) are provided for the agent components and the management component. The agent components update their MIBs with information of the communication network, such as changes in a television event schedule. The management component periodically reads the agents' MIBs to obtain the updated information and store it in its own MIB.Type: GrantFiled: June 12, 1998Date of Patent: January 2, 2001Assignees: Motorola, Inc., General Instrument CorporationInventor: Branislav N.
