New security threats against chips containing scan chain structures
2011
2011 IEEE International Symposium on Hardware-Oriented Security and Trust
Insertion of scan chains is the most common technique to ensure observability and controllability of sequential elements in an IC. However, when the chip deals with secret information, the scan chain can be used as back door for accessing secret (or hidden) information, and thus jeopardize the overall security. Several scan-based attacks on cryptographic functions have been described and showed the need for secure scan implementations. These attacks assume a single scan chain. However the
