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.
Claims20
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.
1 more element
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.
2 more elements
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.
