| Abstract | The personal banking and ID sector has seen a tremendous change in recent years, partially caused by the widespread introduction of smart-cards. Because of the extensive implications of a successful attack on these devices, a wide range of practical as well as purely academic attacks has been developed during the last years. These attacks have unveiled weaknesses in hardware as well as software implementations of several different, partially widely used cryptographic algorithms. An especially powerful method, the differential power analysis (DPA), extracts secret information from power consumption and electro-magnetic emission profiles. The efficiency of a DPA attack significantly depends on the quality of the cryptographic algorithm implementation. These traces currently can only be generated using real hardware or simulation-based approaches. Depending on the chosen simulation accuracy these evaluations result in time-consuming RTL and SPICE simulations often limiting the maximum amount of available execution traces. This paper introduces a novel high-speed methodology for early security evaluations of integrated processor systems using power emulation. First, the usage of power emulation hardware allows for the estimation of attack effort that an adversary will have to invest to gain secret information from an algorithm's execution profile. Second, countermeasures against differential power analysis attacks can be quickly evaluated in terms of effectiveness. The shown approach uses semi-automatic characterization techniques and fully synthesizable emulation hardware to reduce the designer's dependency on time-consuming simulation runs. |

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.
