Automobile is an important application of CPS (Cyber Physical System). However, current software development process in the automotive industry is not adequate to solve the unique problems of CPS. This paper pinpoints the limitations of the current automotive software development process in the perspective of CPS and proposes a new kernel-based approach called HW componentizing kernel as a solution.

ABSTRACT

A physical unclonable function is a one-way function with a mapping determined by uncontrolled, but static, variations of a physical object. A PUF can be used for storage-less cryptographic key generation and authentication. The challenges of engineering a PUF is to make it stable, unique, unclonable, unpredictable and one-way.

This poster describes several recent results in this project, including a microprocessor-based PUF, a method to analyze aging effects in PUFs, and a public database to store PUF data for evaluation.
