  7. Abstract:
  8. Today's latest technology integrated circuits are manufactured for a wide range of applications. With the constant increase in the usage rate of integrated circuits, designing a high reliable system is of utmost importance. The avoidance of counterfeit components is a major challenge of hardware security and trust. Counterfeit components cause lower performance and reduced life span. They are of great concern to the manufacturers and consumers of electronic systems, impacting the security and reliability of these systems. If these parts end up in critical applications like medical systems, satellites, aerospace, or power plants, the results could be catastrophic. So far, there are different methods in place for avoiding counterfeit chips. However, proposed approaches provide time overhead, area overhead and high cost. Among all of the counterfeit types, recycled counterfeit components are the most common ones, because of their low cost and large profit margin. We propose an efficient scan chain based scheme which detects counterfeit ICs by using the aging effects on parameters. Simulations have been done by HSPICE. Results show that by using sub-threshold region properties, delay variation has been improved by a factor of 9.2 in comparison to previous work. Also, current and power degradations have doubled and tripled, respectively. So, the detection capability of recycled ICs is improved. Low overhead of proposed approach makes it a suitable choice for being used for identifying recycled ICs
