US 2010/0138654 A1 · SYSTEM AND METHOD FOR AUTHENTICATION BASED ON PARTICLE GUN EMISSIONS

Abstract

A system, method and computer readable medium are disclosed for authentication. The method includes generating a challenge on a sender based on physical emission properties of a particle gun; transmitting the challenge from the sender to a receiver; receiving the challenge on the receiver; and verifying the authenticity of an entity, such as data, an object or a person, at the receiver by comparing the challenge with a value generated at the receiver. The process of generating the challenge and value is such that it is difficult to retrieve details of the input data based on the output data.

Dependent claims

A method of authentication, the method comprising:

generating a first challenge value on a sender;
transmitting the first challenge value from the sender to a receiver;
receiving the first challenge value on the receiver;
generating a second challenge value at the receiver;
computing a receiver response based on the first challenge value, the second challenge value and a secret, the computing of the receiver response being based on physical emission properties of a particle gun;
transmitting the receiver response to the sender;
and
verifying authenticity of an entity at the sender by comparing an expected value of the receiver response with a calculated value based on the first challenge value, the second challenge value, a secret and being based on the physical emission properties of the particle gun.
