Countermeasures against side channel attacks - e.g. power attacks, based on an analysis of the power consumption, or electromagnetic attacks, which are based on the measurement of electromagnetic emanations - play an important role in modern implementations of cryptographic algorithms on Smart Cards or other security tokens. This has led to significant higher efforts in the implementation of cryptographic libraries for these platforms. At least during two stages of the development process, measurements on the hardware platform become necessary. After giving a short introduction, this paper outlines the some of the current threats and possible countermeasures. One focus is set on describing how this problem influences the complete development process.
