| Abstract | The use of the Advanced Encryption Standard (AES) has become pervasive in a large number of communication applications. The hardware to implement AES is non trivial and as a result it has a significant overhead in its raw form. Despite the algorithm being inherently secure, side channel attacks have exposed potential weaknesses via the implementation route, particularly power analysis. As a result, much effort has been expended in identifying techniques to mask the power signature that can give away the secret key. Unfortunately, the hardware overhead is usually a significant proportion of the size of the original algorithm and in addition, the key can sometimes still be ascertained due to manufacturing differences (such as track lengths) still delivering aspects of the key in a power signature. This paper describes an approach that requires a simple modification to the implementation of the AES algorithm, without altering its basic characteristics, which provides a significantly improved strength against side channel attacks with a minimal additional hardware overhead. |

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.
