US 2016/0080151 A1 · Systems and Methods of Authentication of Communications

Abstract

A system and method of authenticating a communication network comprising a first computing device, a second computing device and an intermediary computing device, wherein there is a first path between the first computing device and the intermediary computing device and a second path between the second computing device and the intermediary computing device. The method is executed at the intermediary computing device, and comprises receiving, from the first computing device, a first session key generated by the first computing device using a function, wherein an input to the function comprises an incremented variable; receiving, from the second computing device, data associated with a second session key generated by the second computing device using the function; determining that the first session key and the second session key are the same; and defining the communication network as authentic when the first session key and the second session key are the same.

Dependent claims

A method of authenticating a communication network comprising a first computing device, a second computing device and an intermediary computing device, wherein there is a first path between the first computing device and the intermediary computing device and a second path between the second computing device and the intermediary computing device, the method being executed at the intermediary computing device and comprising:

receiving, from the first computing device, a first session key, the first session key being generated by the first computing device using a function, wherein an input to the function comprises an incremented variable;
receiving, from the second computing device, data associated with a second session key, the second session key being generated by the second computing device using the function;
determining that the first session key and the second session key are the same;
and
defining the communication network as authentic in the event that the first session key and the second session key are the same.

2 more elements

An intermediary computing device suitable for authenticating a communication network, the communication network comprising a first computing device, a second computing device and an intermediary computing device, wherein there is a first path between the first computing device and the intermediary computing device and a second path between the second computing device and the intermediary computing device, the intermediary computing device comprising:

a first input, arranged to receive a first session key from the first computing device, the first session key being generated by the first computing device using a function, wherein an input to the function comprises an incremented variable;
a second input, arranged to receive data associated with a second session key from the second computing device, the second session key being generated by the issuer using the function;
a processor arranged to determine that the first session key and the second session key are the same, and define that the communication network is authentic in the event that the first session key is identical to the second session key.
