| Abstract | Cognitive radio (CR) technology enables the unlicensed user to access the spectrum holes left by the licensed user (LU), subjecting to a basic requirement of no interference on the active LUs. Nevertheless the LU protection can be misused by malicious CRs through emulating LUs. Observing that the real protection object is the licensed receiver (LR) rather than the licensed transmitter (LT), the research of licensed user emulation attack is dedicated to its genuine form, LR emulation (LRE) attack. Based on the analysis on all possible defense schemes, a digital signature based LRE defense system in the simplex licensed network (SLN) environment is proven practical. The defense mechanism is composed of signature design for LR authentication, as well as the design of public key infrastructure (PKI), used for the distribution of certificates for the LR signatures. With the aim to minimize the communication cost for maintaining the PKI, we propose a certification tree with LR ramification (CTLR) mechanism for certificate request and reply. |

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.
