Device for Generating A Random Electrical Signal and Associated Architecture

A device for generating a random electrical signal, comprising:

• at least one input duct;
• at least one output duct;
• a generator of magnetic particles capable of generating magnetic particles in the input duct;
• a diffusion chamber connected to at least one input duct and to at least one output duct, wherein the diffusion chamber is able to diffuse the generated magnetic particles;
• a unit for displacement of the generated magnetic particles towards the diffusion chamber;
• and
• a converter that is designed to generate an electric signal proportional to a characteristic relating to the magnetic particles, wherein the characteristic is the density of magnetic particles in said diffusion chamber, or the passage of magnetic particles at a predetermined location of an output duct connected to said diffusion chamber.
