| Abstract | The level of security provided by digital rights management functions and cryptographic protocols depend heavily on the security of an embedded secret key. The current practice of embedding the key as digital data in the integrated circuit (IC) weakens these security protocols because the keys can be learned through attacks. Physical unclonable functions (PUFs) are a recent alternative to storing digital keys on the IC. A PUF leverages the inherent manufacturing variations of an IC to define a random function. Given environmental variations such as temperature and supply noise, PUF quality criteria such as reproducibility and the level of randomness in the responses may be difficult to achieve for a given PUF circuit architecture. In this paper, we evaluate a PUF derived from the power distribution system of an IC with regard to a set of quality metrics including single-bit and collision probability and entropy. The analysis is carried out using data obtained from 36 chips fabricated in IBM's 65 nm SOI technology. |

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.
