Reducing Area & Power Overhead In Design of Light Weight Sensor For Detection of Reclcled ICS

摘要

The counterfeiting and recycling of integrated circuits (ICs) have become major issues in recent years, potentially impacting the security and reliability of electronic systems bound for military, financial, or other critical applications. With identical functionality and packaging, it would be extremely difficult to distinguish recycled ICs from unused ICs. In the existing Ring Oscillator (RO) based sensor with 90nm technology test chip shows the effective detection of recycled ICs. The impact of RO based sensor is that, it is difficult to identify recycled ICs used shorter than one month and it requires more power and area overhead. To provide a solution to the existing system, Clock Anti fuses (CAF) based sensor is implemented to enhance the effective recognition of recycled ICs even if the IC used for a very short period. MAF is implemented in FPGA to verify its effectiveness.
