Patent number: 8111089Abstract: A logical building block and method of using the building block to design a logic cell library for CMOS (Complementary Metal Oxide Silicon) ASICs (Application Specific Integrated Circuits) is disclosed. Different logic gates, built with the same building block as described in this invention, will have the same schematics of transistor connection and also the same physical layout so that they appear to be physically identical under optical or electron microscopy. An ASIC designed from a library of such logic cells is strongly resistant to a reverse engineering attempt.Type: GrantFiled: May 24, 2010Date of Patent: February 7, 2012Assignees: Syphermedia International, Inc., Promtek Programmable Memory Technology, Inc.Inventors: Ronald P.

Publication number: 20110030023Abstract: A method, apparatus, article of manufacture, and a memory structure for delivering purchase information comprising storing purchase information for a purchase of a user in a set top box. The set top box (STB) is configured to receive and display the broadcast signals through a tuner onto a display device. The STB establishes a connection to the Internet through a user initiated action (e.g., when the user accesses the Internet using the STB). A new transmission control/Internet protocol (TCP/IP) connection is obtained using the established user-initiated Internet connection without the user requesting the connection. A secure electronic connection is established with a server through the new TCP/IP connection. The purchase information is then transmitted from the STB through the secure electronic connection to the server.Type: ApplicationFiled: October 11, 2010Publication date: February 3, 2011Applicant: The DIRECTV Group, Inc.Inventors: Ronald P.

Patent number: 7548624Abstract: Program materials received from a direct broadcast satellite system are distributed between a host receiver and a client receiver for remote decryption. Using either a same pairing key or different host and client pairing keys, an encrypted media encryption key is received at both the host and client receivers, and the encrypted media encryption key is decrypted at both the host and client receivers using the pairing key. Encrypted program materials are received from the broadcast system at the host receiver, and the encrypted program materials are decrypted at the host receiver using the media encryption key. The encrypted program materials are also transferred from the host receiver to the client receiver, where the encrypted program materials are decrypted at the client receiver using the media encryption key.Type: GrantFiled: January 16, 2004Date of Patent: June 16, 2009Assignee: The DIRECTV Group, Inc.Inventors: Raynold M.

Patent number: 7457967Abstract: One or more embodiments of the invention provide a method, apparatus, and article of manufacture for limiting unauthorized access to digital services. A hidden non-modifiable identification number is embedded into a nonvolatile memory component. The nonvolatile memory component is used to contain state information to provide desired functionality and enforce one or more security policies for accessing the digital services. Also, the hidden number uniquely identifies a device containing the nonvolatile memory component and access to the digital services is based on access rights associated with the hidden number. Once embedded, access to the nonvolatile memory component is isolated such that access to the identification number is limited to a fixed state custom logic block, the nonvolatile memory component is protected from modification such that it is read only, and the nonvolatile memory component is not directly accessible via a system bus.Type: GrantFiled: February 28, 2002Date of Patent: November 25, 2008Assignee: The DIRECTV Group, Inc.Inventors: Ronald P.
