7587587, Sep 8, 2009

Filed:

Dec 4, 2003

Appl. No.:

10/727430

Inventors:

Mark L. Buer - Gilbert AZ, US
Scott S. McDaniel - Villa Park CA, US
Uri Elzur - Irvine CA, US
Joseph J. Tardo - Palo Alto CA, US
Kan Fan - Diamond Bar CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04L 29/08
H04L 9/00

US Classification:

713153, 713151

Abstract:

Methods and associated systems provide secured data transmission over a data network. A security device provides security processing in the data path of a packet network. The device may include at least one network interface to send packets to and receive packets from a data network and at least one cryptographic engine for performing encryption, decryption and/or authentication operations. The device may be configured as an in-line security processor that processes packets that pass through the device as the packets are routed to/from the data network.

Appl. No.:

10/728192

Inventors:

Mark Buer - Gilbert AZ, US
Scott McDaniel - Villa Park CA, US

International Classification:

H04L009/00

US Classification:

713/150000

Abstract:

Methods and associated systems are disclosed for providing secured data transmission over a data network. Data to be encrypted and encryption information may be sent to a security processor via a packet network so that the security processor may extract the encryption information and use it to encrypt the data. The encryption information may include flow information, security association and/or other cryptographic information, and/or one or more addresses associated with such information. The encryption information may consist of a tag in a header that is appended to packets to be encrypted before the packets are sent to the security processor. The packet and tag header may be encapsulated into an Ethernet packet and routed via an Ethernet connection to the security processor.
