Network authentication based on inter-packet gap characteristics
First Claim
Patent Images
1. A method of authenticating network communications, comprising:
- transmitting or receiving a first frame across a network;
wherein said first frame is transmitted or received with an inter-packet gap associated with said first frame, said inter-packet gap having one or more inter-packet gap characteristics; and
wherein said one or more inter-packet gap characteristics are employed as at least a part of an inter-packet gap authentication criteria for said network.

Abstract
Network communications in physical layer frame-based networks may be authenticated based on inter-packet gap (IPG) characteristics such as inter-packet gap length, inter-packet gap length pattern, information contained in the inter-packet gap, etc.

7. A method of processing information communicated across a network using a frame-based network protocol, comprising:
-
receiving a frame stream from across a network in a first information handling system configured as a first network node, said frame stream comprising one or more frames and inter-packet gaps having an inter-packet gap length, and each of said one or more frames being associated with one of said inter-packet gaps;
using physical layer processing to examine said inter-packet gap length associated with each of said one or more frames;
accepting a first frame of said one or more frames if said inter-packet gap length associated with said first frame is greater than or equal to a minimum inter-packet gap length specified for said network protocol, and if said inter-packet gap length associated with said first frame meets an inter-packet gap authentication criteria policy; and
rejecting said first frame associated with said one or more frames if said inter-packet gap length associated with said first frame does not meet said inter-packet gap authentication criteria policy. - View Dependent Claims (8, 9, 10, 11)

12. A network node system, comprising:
-
an information handling system configured to be coupled to a network as network node, said information handling system being configured to transmit or receive a first frame and inter-packet gap associated with said first frame across a network;
wherein said inter-packet gap has one or more inter-packet gap characteristics; and
wherein said one or more inter-packet gap characteristics are employed as at least a part of an inter-packet gap authentication criteria for said network. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
