An authentication method using a plurality of physical unclonable functions (PUFs). The plurality of PUFs includes a first PUF associated with a first device and a second PUF associated with a second device. A surface pattern of the first PUF corresponds to a surface pattern of the second PUF. The method includes obtaining a first response to a challenge using the first PUF, sending a request to the second device for a second response to the challenge obtained used the second PUF, receiving the second response, and determining whether the second device is authenticated based on a comparison between the first response and the second response.
An authentication method using a plurality of physical unclonable functions (PUFs), the plurality of PUFs comprising a first PUF associated with a first device and a second PUF associated with a second device, a surface pattern of the first PUF corresponding to a surface pattern of the second PUF, the method comprising:
A first device for use in authenticating a second device, the first device associated with a first physical unclonable function (PUF) and the second device associated with a second PUF, a surface pattern of the first PUF corresponding to a surface pattern of the second PUF, the first device configured to:
A method of manufacturing a plurality of physical unclonable functions (PUFs), the method comprising:
