J. den Hartog, J. Verschuren, E. de Vink, J. de Vos and W. Wiersma PINPAS: a tool for power analysis of smartcards This paper describes the PINPAS tool, a tool for the simulation of power analysis and other side-channel attacks on smartcards. The PINPAS tool supports the testing of algorithms for vulnerability to SPA, DPA, etc. at the software level. Exploitation of the PINPAS tool allows for the identification of weaknesses in the implementation in an early stage of development. A toy algorithm is discussed to illustrate the usage of the tool.
