US Patent:

8166296, Apr 24, 2012

Filed:

Aug 5, 2005

Appl. No.:

11/197815

Inventors:

Mark Buer - Gilbert AZ, US
Ed Frank - Atherton CA, US
Nambi Seshadri - Irvine CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04L 9/32

US Classification:

713168, 726 5

Abstract:

Techniques are provided for users to authenticate themselves to components in a system. The users may securely and efficiently enter credentials into the components. These credentials may be provided to a server in the system with strong authentication that the credentials originate from secure components. The server may then automatically build a network by securely distributing keys to each secure component to which a user presented credentials.

Appl. No.:

11/298153

Inventors:

Mark Buer - Gilbert AZ, US
Ed Frank - Atherton CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04K 1/00

US Classification:

380255, 380 28

Abstract:

An input device with an integrated security module communicates with a processing component over an insecure medium. The insecure medium may be a wireless network, software stack, or the like. According to one embodiment, the security module is integrated into an existing chip of the input device. Data generated by the input device is encoded and/or authenticated by the security module prior its transmission to the processing device. The processing device receives the input data and processes it within its own security boundary for providing selected services or information to a user or application associated with the input device.

Broadcom Corporation - Irvine CA

International Classification:

G06K 5/00

US Classification:

235380, 235381, 235375, 235382, 713155, 713161, 713169, 713170, 713168, 713172, 713184, 713201, 726 2, 726 3, 726 4, 726 5, 726 21, 726 27, 726 28, 726 29, 726 30, 726 9, 380255, 380270, 455411

Abstract:

Access to secured services may be controlled based on the proximity of a wireless token to a computing device through which access to the secured services is obtained. An authorized user may be provided access to a service only when a wireless token assigned to the user is in the proximity of the computing device. A user's credential may be stored on an RFID token and an RFID reader may be implemented within a security boundary on the computing device. Thus, the credential may be passed to the security boundary without passing through the computing device via software messages or applications. The security boundary may be provided, in part, by incorporating the RFID reader onto the same chip as a cryptographic processing component. Once the information is received by the RFID reader it may be encrypted within the chip. As a result, the information may never be presented in the clear outside of the chip.

Appl. No.:

11/204596

Inventors:

Mark Buer - Gilbert AZ, US
Ed Frank - Atherton CA, US

International Classification:

H04L 9/00

US Classification:

713155000

Abstract:

Techniques are provided to authenticate components in a system. Users may enter credentials into an input device and the credentials may be authenticated and/or securely transmitted to the components. The components may then provide the credentials to a server in the system. Strong authentication may thus be provided to the effect that credentials associated with specific users have been received from specific components in the system. The server may then enable the components to access selected services.
