Security Analysis of Industrial Test Compression Schemes

Amitabh Das, Baris Ege, Santosh Ghosh, Lejla Batina, Ingrid Verbauwhede
2013 IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems  
Test compression is widely used for reducing test time and cost of a VLSI circuit. It is also claimed to provide security against scan based side-channel attacks.  ...  This paper pursues the legitimacy of this claim and presents scan attack vulnerabilities of test compression schemes used in commercial EDA tools.  ...  This is implemented by masking the parity bitstream on the output of the test response compactor instead of the data before being captured in the scan chain.  ...
