Title:
Information Leakage Reduction at the Scan-Path Output 
Abstract:
In this paper we present a new scan-path structure for improving the security of systems including a scan path, which normally introduces a security critical information channel into a design. The structure, named differential scan path (DiSP), divides the internal state of the scan path into two sections. During shift-out operation, only subtraction of the two sections is provided. The discovery of the internal state from this subtraction requires guesswork that increases exponentially with sca...    »
