| Abstract | With the rapid growth of low-cost, low-power handheld devices with wireless capability, more and more devices connect to wireless networks. This warrants secured data exchange and authentication to take place during the connection. 802.11i security scheme is becoming a de- facto standard of future WLAN, which uses AES algorithm in both encryption and authenticity of payload data. Cryptographic transformations of AES are computationally intensive, consuming significant power. Most of the published AES implementations target high- end products with multi-gigabit throughputs and have no regards for power consumption. Low-end products, including handheld devices like PDA rarely need more than 200 Mbps data transfer rate which necessitates alternative implementation of AES algorithm, with the aim of reducing power consumption and increasing the handsets' battery life. In this paper we study and compare the outcome obtained from implementing AES algorithm on various platforms. We present results obtained through profiling the implemented algorithm on platforms like FPGA, Desktop PC (Microsoft Visual Studio) and handheld device (UIQ SDK for Symbian OS along with Metrowerks CodeWarrior). Our comparison shows that the 32-bit hardware implementation of AES on FPGA supports the required throughput and consumes less power allowing fully charged PDA to remain connected to WLAN for a longer duration. |

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.
