System and method for providing secure network communications

摘要

A method includes receiving a data message, from a first embedded node, in a first end point device. The first data message is addressed to a second embedded node. The method also includes encrypting the first data message to produce an encrypted data message, where the encryption is transparent to the first embedded node. The method further includes transmitting the encrypted data message to a second end point device. An apparatus includes a plurality of embedded node ports each configured to communicate with an embedded node. The apparatus also includes an encrypted communications link port configured to communicate with an end point device. The apparatus further includes a controller connected to communicate with the embedded node ports and the encrypted communications link port. In addition, the apparatus includes a storage connected to be read from and written to by the controller.

1. A method comprising:
receiving a first data message, from a first embedded node, at an embedded node port of a first end point device, the first data message being addressed to a second embedded node, the embedded node port configured to communicate with the first embedded node; encrypting the first data message using a Layer 2 encryption process to produce an encrypted data message, the encryption being transparent to the first embedded node, the encryption process performed by an encryption controller having a secure encrypted memory not accessible to an end user; communicating the encrypted data message from the encryption controller to an encrypted communications link port over a media independent interface (MII) bus; and transmitting the encrypted data message from the encrypted communications link port to a second end point device.
