Dynamic Behavior of RS latches using FIB processing and probe connection

Abstract

PUF (Physically Unclonable Function) technologies attract attention as a candidate to prevent counterfeit chips. A latch PUF is known as a high performance PUF among various types of proposed PUFs. In this paper we describe an experiment on a dynamic attack to a latch PUF consisting of RS latches, such as measuring the latch output by a probe connection after a FIB (Focused Ion Beam) processing. As a result, we confirmed that the latch PUF using the RS latch has a tolerance for the dynamic analysis, because the RS latch output was influenced and changed by the FIB processing in our experiment.

Note: Two data in the number of latches in Table 4 is correctly revision.
