Physical Unclonable Functions (PUFs) with Memories Containing Ternary States

Description

Physical unclonable functions (PUFs) strengthen the security of authentication methods by acting as a virtual “fingerprint” of the hardware, delivering unique signatures during the authentication process. PUFs exploit intrinsic manufacturing variations which are naturally introduced during the fabrication of hardware. This technology utilizes PUFs for memories containing ternary states based on commercially available memory architectures. The resulting data streams used for hardware authentication are extremely stable and predictable, needing little to no error correction. Additionally, the authentication process is less susceptible to side-channel attacks by hackers.
