| Abstract | Template attack is more powerful than SPA and CPA in some situations. In this paper, a novel template attack named DTTA is proposed to attack the wNAF algorithm of ECC. SM2 is the Chinese public key cryptosystem standard issued in 2010. Few results of side channel attack on SM2 have been found so far. We exploit the Riscure platform to analyze decryption of SM2 in a smart IC card. We also compare 3 kinds of method which used in template matching phase. Experiment results show that template matching method of multivariate normal distribution is superior to correlation method or LSM. The maximum success rate of template matching can be 88%. That means a 256-bit private key of SM2 can be recovered 225 bits by only acquiring one measurement of SM2 decryption in average. Some general countermeasures is not safe enough for DTTA. Defensive strategy should exploit the combination of multiple countermeasures to resist DTTA. |

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.
