| Abstract | Prior work has shown that printed circuit board (PCB) reverse engineering can be accomplished with inexpensive home solutions as well as state-of-the-art technologies. Once the information of how components on a PCB are connected is determined, an adversary can steal the IP, clone the design, determine points of attack on a system, etc. Existing chip-level obfuscation techniques are not applicable to board level due to the significant differences between chips and PCBs. In this paper, we propose a PCB obfuscation approach that relies on permutation blocks to hide the interconnects among the PCB's circuit components. A detailed framework is provided to implement the proposed approach and evaluate its performance. Potential attacks and countermeasures are also discussed. Results obtained from five industrial reference designs show that it is nearly impossible to break the proposed approach by brute force, even under pessimistic assumptions. Our investigation also reveals that PCBs containing a programmable component with 64 pins (or more) are well-protected by our approach, making it suitable for a large percentage of systems and applications. |

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.
