| Abstract | Since Radio-Frequency Identification (RFID) systems have become commonplace in access control and security applications, the usage and importance of cryptographic co-processors in RFID transponder devices has grown significantly. Improved vehicle security systems, also known as immobilizers, are required due to increased vehicle theft worldwide. Such devices, and embedded systems in general, must provide high security at low cost and low power. In order to overcome proprietary algorithms with respect to the system manufacturers, a new Universal Immobilizer Crypto Engine (UICE) is proposed. This UICE algorithm is tailored to 8-bit microprocessor architectures and is therefore very fast in software and hardware. The dedicated hardware implementation leads to a small gate count, because the registers for input (challenge) and output (response) are shared. The important non-linear function, in this case an 8 /spl times/ 8 S-Box, may be built as a gate array or small ROM, which has the advantage of flexibility. Several tests - statistical and random-number - have been performed in order to analyze the strength of the algorithm. So far no weakness was found after ten rounds of encryption. |

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.
