Patent number: 9288055Abstract: Methods and systems are provided for verifying use of encryption keys. A request for verification information may be sent by a network element (e.g., server), with the request comprising combination of one or more identifiers, the combination associated with a particular I/O operation. The request may be sent to another element, which may be a centralized encryption management element (e.g., management server). In response to the request, key use verification information generated for the particular I/O operation may be received, and may be used thereafter in validating a corresponding encryption key, which may be used during data encryption or decryption, based on the received key use verification information and locally generated verification information associated with the particular I/O operation. The one or more identifiers include at least one of a target identifier, a LUN identifier, and a LBA range identifier.Type: GrantFiled: February 26, 2015Date of Patent: March 15, 2016Assignee: Avago Technologies General IP (Singapore) Pte. Ltd.Inventors: John Sui-kei Tang, Larry Dean Hofer, David C. Lawson

Patent number: 8995654Abstract: A method for sending encrypted data in response to a request for an I/O operation. The method includes the steps of requesting a data encryption key, the request including one or more identifiers unique to the I/O operation; receiving a data encryption key attached with a first key use fingerprint, independently generating a second key use fingerprint in response to the one or more identifiers; comparing the first and the second key use fingerprints; and if the first key use fingerprint matches the second key use fingerprint, using the data encryption key to encrypt the data to be sent. In one embodiment, the one or more identifiers include at least one of a target identifier, a LUN identifier, and a LBA range identifier.Type: GrantFiled: May 28, 2009Date of Patent: March 31, 2015Assignee: Emulex CorporationInventors: John Sui-kei Tang, Larry Dean Hofer, David Lawson

Patent number: 5212494Abstract: The disclosure relates to a multipolarized broad band antenna and antenna system wherein the antenna structure is formed on a substrate, the antenna structure on the substrate including a central feedpoint, a first antenna element having a plurality of regions composed of first plural interconnected concentric sectors of circles of diminishing radius extending to the feedpoint, and a second antenna element having a plurality of regions composed of second plural interconnected concentric sectors of circles of diminishing radius extending to the feedpoint, the second plural concentric sectors being interleaved with the first plural concentric sectors.Type: GrantFiled: October 31, 1990Date of Patent: May 18, 1993Assignee: Texas Instruments IncorporatedInventors: Dean A.

Patent number: 5191351Abstract: A folded broadband antenna provides a symmetrical radiation pattern comparable to corresponding planar antennas (such as a planar spiral). The folded antenna can be integrated into a leading edge radome, eliminating the forward antenna cavity, and thereby, eliminating the internal wall reflections that cause radiation pattern distortion. A broadband antenna (61/62), such as an archimedean spiral, is folded at an apex area (64) that includes a fold-slot (66). The fold-slot enhances flexure, and allows a center-feed balun shielding tube (84) to extend into close proximity to the antenna aperture (61) for increased balun shielding.Type: GrantFiled: December 29, 1989Date of Patent: March 2, 1993Assignee: Texas Instruments IncorporatedInventors: Dean A. Hofer, Matthew L. Pecak

Patent number: 4697192Abstract: A broadband two arm planar/conical/helix antenna is disclosed. The antenna radiation element includes a two arm planar spiral antenna section, a two arm conical spiral section connected to the planar spiral section and a four arm helix section connected to the conical spiral section for termination. The antenna element is formed on a fiberglas substrate which contains a molded internal load absorber. A tapered magnetic external load absorber covers the antenna radiation element. The supporting fiberglas substrate is fixed to a balun housing. The balun housing has a centrally disposed, upwardly extending tubular means for passing a feed line to the planar spiral section.Type: GrantFiled: April 16, 1985Date of Patent: September 29, 1987Assignee: Texas Instruments IncorporatedInventors: Dean A. Hofer, Daniel J. Carlson, Matthew L. Pecak
