Patent number: 8397082Abstract: A method (200) and program (100) for inhibiting attack upon a computer (120) is provided. The address (104) of a process (106) is produced (612), and encrypted (616) to produce an encrypted address (518), which is then stored in memory (128). When needed, the encrypted address (518) is retrieved (702) from memory (128) and decrypted (704) to reproduce the original process address (104). The reproduced process address (104) is then verified (708). If the process address (104) is determined (708) to be valid, i.e., there was no attack, then the process address (104) is placed (712) in the program counter (318), and a valid process (106) is executed. If the process address (104) is determined (708) to be invalid, i.e., there was an attack, then the address (108) of a crash and terminate process (110) is placed (716) in the program counter (318) and the computer (120) crashes. A nonce value (512) may be generated (602) and encrypted (616) and decrypted (704) in conjunction with the process address (104).Type: GrantFiled: September 30, 2010Date of Patent: March 12, 2013Assignees: Verizon Corporate Services Group Inc., Raytheon BBN Technologies Corp.Inventor: Walter Clark Milliken

Patent number: 8335224Abstract: A data-buffering apparatus (100) having two buffers (206,200) and configured to conserve power is disclosed. When a block of data (202) having a short block length (406?) is to be buffered, the block of data (202) is buffered by a small primary buffer (206) and a large secondary buffer (200) is deactivated. When a block of data (202) having a long block length (406?) is to be buffered, the large secondary buffer (200) is activated and the block of data (202) is buffered by both buffers (206,200). As there are typically many more blocks of data (202) having short block lengths (406?) than long block lengths (406?), the secondary buffer (200) is activated only a small fraction of the time.Type: GrantFiled: August 28, 2002Date of Patent: December 18, 2012Assignee: Raytheon BBN Technologies Corp.Inventor: Walter Clark Milliken

Patent number: 8321938Abstract: A network analysis architecture provides a suite of complementary logic operable at different temporal and spatial timescales. The distinct temporal and spatial scales define different tiers, each analyzing network events according to predetermined temporal and spatial scales of progressive magnitude. Particular event detection logic may be operable on an immediate temporal scale, while other logic identifies trends over a longer time period. Similarly, different spatial scales are appropriate to different algorithms, as in logic that examines only headers or length of packets, or inspects an entire payload or transferred file. Deployment of logic that is focused on different timing and scope of data allows timely action in the case of readily apparent deviations, and permits longer term analysis for identifying trends that emerge over time.Type: GrantFiled: February 12, 2009Date of Patent: November 27, 2012Assignee: Raytheon BBN Technologies Corp.Inventors: William Timothy Strayer, Walter Milliken, Ronald Joseph Watro

Patent number: 8315998Abstract: Methods and apparatus for searching Semantic Web structured resources and presenting the search results to a user can increase the likelihood that the search can produce meaningful results. An index database can be constructed by parsing literal values from statements from the resources to obtain component words of the literal values, with the index relating the component words to the statements from which they were parsed. A search engine can obtain component words from the database that match search terms in a query prepared by the user and can obtain the related statements for the matching words. A servlet or other application using the search engine and database can obtain predicates, instances, types of said instances, and full literal values of said instances for the related statements. The search results can be presented to the user as a summary of the predicates, instances, types, and full literal values.Type: GrantFiled: March 18, 2004Date of Patent: November 20, 2012Assignees: Verizon Corporate Services Group Inc., Raytheon BBN Technologies Corp.Inventor: Michael Anthony Dean

Publication number: 20120269067Abstract: The present invention increases the available spectrum in a wireless network by sharing existing allocated (and in-use) portions of the RF spectrum in a manner that minimizes the probability of interfering with existing legacy users. Interference temperature-adaptive waveforms, and a variety of physical and media access control protocols for generating waveforms based on measurement and characterization of the local spectrum are provided. The invention measures the local spectrum at a receiving node, generates an optimal waveform profile specifying transmission parameters that will water-fill unused spectrum up to an interference limit without causing harmful interference to primary and legacy transmitters using the same frequency bands, and enables simultaneous transmit and receive modes at multiple transceivers in a wireless network.Type: ApplicationFiled: April 25, 2012Publication date: October 25, 2012Applicant: Raytheon BBN Technologies Corp.Inventor: Jerry D.

Patent number: 8260817Abstract: The invention relates to topic classification systems in which text intervals are represented as proposition trees. Free-text queries and candidate responses are transformed into proposition trees, and a particular candidate response can be matched to a free-text query by transforming the proposition trees of the free-text query into the proposition trees of the candidate responses. Because proposition trees are able to capture semantic information of text intervals, the topic classification system accounts for the relative importance of topic words, for paraphrases and re-wordings, and for omissions and additions. Redundancy of two text intervals can also be identified.Type: GrantFiled: January 24, 2011Date of Patent: September 4, 2012Assignee: Raytheon BBN Technologies Corp.Inventors: Elizabeth Megan Boschee, Michael Levit, Marjorie Ruth Freedman
