PUF based Implantable Medical Device Security

Seonghan Ryu

Abstract

For the resource-constrained device such as Implantable Medical Device(IMD), lightweighting cryptographic methods are required. Physical unclonable function(PUF) is promising hardware based lightweight security solution, which makes use of the inherent process variation in semiconductor fabrication process to generate unique ID. This paper presents an PUF based IMD security with local oscillator(LO) chain composed of VCO and dynamic divider(DDiv), which use self oscillation frequency(SoF) variation characteristics. In the LO chain PUF implementation, the output bits are obtained by comparing the oscillation frequencies of different VCO L banks or dynamic dividers. For the lightweight operability, simple VCO and DDiv-PUF based authentication protocol is also proposed.
