A research team from Securosys and the University of Applied Science (HSR) in Rapperswil, Switzerland, worked on exactly these topics in a project supported by the Federal Commission for Technology and Innovation (CTI). The findings of this project are available now. In their report, the researchers from the Institute of Microelectronics and Embedded Systems (IMES) and Securosys show, how an elliptic-curve-based (ECC) algorithm is successfully attacked at first, and how slight modifications lead to robustness against side-channel attacks.
