US Patent:

7502474, Mar 10, 2009
Filed:

May 6, 2004
Appl. No.:

10/839872
Inventors:

Marufa Kaniz - Santa Clara CA, US
Jeffrey Dwork - San Jose CA, US
Robert Alan Williams - Cupertino CA, US
Mohammad Maniar - Saratoga CA, US
Somnath Viswanath - Bangalore, IN
Assignee:

Advanced Micro Devices, Inc. - Sunnyvale CA
International Classification:

H04K 1/00
US Classification:

380255, 713189, 713192
Abstract:

One aspect of the invention relates to a network interface system for interfacing a host system with a network. The network interface system includes a bus interface system, a media access control system, and a security system. The security system selectively perform security processing on data incoming from the network based on security associations stored in a memory external to the network interface system, typically a host system memory. The security association for any given frame, when available, is fetched from the external memory after the frame begins to arrive in the network interface system based in part on information contained in the frame. Preferably, the fetch begins before the frame is fully received and the security association is queued whereby security processing can begin without having to wait for the security association to be fetched.

7512787, Mar 31, 2009
Filed:

Feb 3, 2004
Appl. No.:

10/771019
Inventors:

Somnath Viswanath - San Jose CA, US
Mohammad Maniar - Saratoga CA, US
Jeffrey Dwork - San Jose CA, US
Robert Alan Williams - Cupertino CA, US
Assignee:

Advanced Micro Devices, Inc. - Sunnyvale CA
International Classification:

H04L 9/00
US Classification:

713160
Abstract:

The invention relates to a network interface system for interfacing a host system with a network. The network interface system includes a bus interface system, a media access control system, and a security system. The security system is operative to selectively authenticate incoming and outgoing data. The security system includes a pipeline that masks mutable fields from incoming data prior to authentication.

Filed:

Sep 21, 2004
Appl. No.:

10/945802
Inventors:

Somnath Viswanath - Bangalore, IN
Jeffrey Dwork - San Jose CA, US
Robert Alan Williams - Cupertino CA, US
Marufa Kaniz - Santa Clara CA, US
Mohammad Y. Maniar - Saratoga CA, US
Assignee:

Advanced Micro Devices, Inc. - Sunnyvale CA
International Classification:

H04L 29/06
US Classification:

713151, 713153, 713160, 726 13, 726 14
Abstract:

A security association architecture system of the present invention facilitates network data transfer by providing an internal portion of a security association database that can be quickly accessed to obtain security associations as well as an external component that stores the complete security association database. As a result, at least some security associations for incoming received frames and outgoing transmitted frames can be obtained from the internal portion located on a network interface device without accessing system memory, a host computer, and the like in order to obtain the security associations to perform security processing.

US Patent:

7685434, Mar 23, 2010
Filed:

Mar 2, 2004
Appl. No.:

10/791557
Inventors:

Marufa Kaniz - Santa Clara CA, US
Jeffrey Dwork - San Jose CA, US
Robert Alan Williams - Cupertino CA, US
Mohammad Y. Maniar - Saratoga CA, US
Somnath Viswanath - San Jose CA, US
Assignee:

Advanced Micro Devices, Inc. - Sunnyvale CA
International Classification:

G06F 21/00
G06F 11/30
US Classification:

713189
Abstract:

The invention relates to a network interface system for interfacing a host system with a network. The network interface system includes a bus interface system, a media access control system, and a security system. The network interface offloads IPsec processing from the host processor. According to the invention, the security system includes two processors for encrypting and authenticating the outgoing data. Outgoing data packets are sent alternately to one or the other processor, whereby transmission processing can be accelerated relative to receive processing.

Circuit For Controlling External Bipolar Buffers From An Mos Peripheral Device

US Patent:

45946540, Jun 10, 1986
Filed:

Nov 4, 1983
Appl. No.:

6/549521
Inventors:

Mohammad Y. Maniar - San Jose CA
Steven Dines - San Jose CA
Assignee:

Advanced Micro Devices, Inc. - Sunnyvale CA
International Classification:

G06F 300
G06F 922
G06F 1342
US Classification:

364200
Abstract:

A circuit for controls external bipolar buffers for an MOS peripheral device capable of operating in master end slave modes. The circuit provides for a slave mode logic block and a master mode logic block for generating a DATA TRANSMIT ENABLE SIGNAL to permit the bipolar buffer to transmit data signals from the peripheral device to a system bus. The circuit also provides for a second slave mode logic block and a master mode logic block for generating a DATA RECEIVE ENABLE block to permit the bipolar buffer to transmit data signals from the system bus to the peripheral device. Each slave mode logic block is responsive to condiion signals, such as CHIP SELECT and READ/WRITE. Each master mode logic block is responsive to timing signals and signals generated internally within the periphel device so that the master mode DATA RECEIVE and DATA TRANSMIT signals occur only in predetermined timing cycles.
