- Abstract
In the template building stage of the traditional template attack method, a large number of calculations are usually needed to calculate the covariance matrix, sometimes the result is even impossible to get. Through the in-depth study of the template attack technology, this paper proposed a new type of attack strategy. With the improvement of the template building, this method greatly simplified the template structure, and successfully solved these problems above. At the same time,it also independently completed the development of the side channel data acquisition platform, and wrote the side channel attack soft-ware used on PC. For AES encryption algorithm in Magel6 microcontroller development board, it performed a DPA attack based on template. The experimental results show that, this method can effectively avoid the numerical calculation problems that the traditional template attack may occur in the process,and compare to the ordinary DPA attacks, it dramatically reduces the number of the energy traces needed, which effectively proves the validity and practicability of the method.
