| Abstract | The counterfeit electronic component industry continues to threaten the security and reliability of systems by infiltrating recycled components into the supply chain. With the increased use of FPGAs in critical systems, recycled FPGAs cause significant concerns for government and industry. In this paper, we propose a two phase detection approach to differentiate recycled (used) FPGAs from new ones. Both approaches rely on machine learning via support vector machines (SVM) for classification. The first phase examines suspect FPGAs “as is” while the second phase requires some accelerated aging. To be more specific, Phase I detects recycled FPGAs by comparing the frequencies of ring oscillators (ROs) distributed on the FPGAs against a golden model. Experimental results on Xilinx FPGAs show that Phase I can correctly classify 8 out of 20 FPGAs under test. However, Phase I fails to detect FPGAs at fast corners and with lesser prior usage. Phase II is then used to compliment Phase I and overcome its limitations. The second phase performs a short aging step on the suspect FPGAs and exploits the aging speed reduction (due to prior usage) to cover the cases missed by Phase I. In our silicon results, Phase II detects all the fresh and recycled FPGAs correctly. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
