Network user identification and authentication
First Claim
Patent Images
1. A method of identifying and authenticating a network user comprising:
- receiving, at a network layer of a network, a first Internet Protocol (IP) version 4 (IPv4) packet from a first user entity, wherein the network layer of the network is layer 3 in an Open Systems Interconnection (OSI) model of the network and wherein the first IPv4 packet includes a first IPv4 packet header that includes;
a first network address; and
first unique identification information that identifies the first user entity, is unique to the first user entity, and is independent of the first network address; and
verifying, at the network layer with the first IPv4 packet header and without use of layers of the OSI model higher than the network layer, that the first IPv4 packet is from the first user entity based on the first unique identification information included in the first IPv4 packet header.

Abstract
A method of identifying and authenticating a network user includes receiving a first network layer packet from a first user entity. The first network layer packet may include first unique identification information unique to the first user entity and independent of a first network address associated with the first network layer packet. The method further includes verifying, at a network layer of a network, that the first network layer packet is from the first user entity based on the first unique identification information.

14. A processor configured to execute computer instructions to cause a system to perform operations for identifying and authenticating a network user, the operations comprising:
-
receiving, at a network layer of a network, a first Internet Protocol (IP) version 6 (IPv6) packet from a first user entity, wherein the network layer of the network is layer 3 in an Open Systems Interconnection (OSI) model of the network and wherein the first IPv6 packet includes; a first IPv6 packet header that includes a first IP address; and a first Hop-by-Hop field that includes first unique identification information that identifies the first user entity, is unique to the first user entity, and is independent of the first IP address; and verifying, at the network layer with the first Hop-by-Hop field and without use of layers of the OSI model higher than the network layer, that the first IPv6 packet is from the first user entity based on the first unique identification information included in the first Hop-by-Hop field of the first IPv6 packet. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
