| Abstract | Traditionally, spread-spectrum systems have been employed to provide low probability-of-intercept (LPI), low probability-of-detection (LPD) performance at the physical layer, but the messages transmitted over such a system are still encrypted with a powerful cipher to protect their secrecy. However, it has recently been suggested that the cryptographic security of the system can be enhanced by exploiting physical properties of ultra-wideband (UWB) signals. With an eavesdropper observing the communications over multipath channels between two legitimate partners sharing a secret key of a limited length, we consider both coherent and reference-based UWB schemes to enhance security. The security of the legitimate nodes is achieved by signal attributes based on the secret key, giving them an advantage over the adversary. In particular, we propose transmission schemes and investigate the physical layer security performance of UWB systems intended for coherent reception and UWB transmitted-reference (TR) systems in IEEE 802.15.4a multipath environments. Critical to the TR scheme is employing true randomness to keep a sophisticated adversary from decoding the signal coherently. Numerical results for IEEE 802.15.4a channel models reveal not only that the proposed schemes provide promising support for higher-layer cryptographic protocols, but also, perhaps surprisingly, that the baseline UWB TR system can demonstrate better security tradeoffs than the baseline UWB system intended for coherent reception under the IEEE 802.15.4a channel model. |

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.
