Looks that it is claims to be protected against all of these attucks

Unlikely. Power filtering cannot help you when the leak is so gross that it makes timing differences you could darn near measure with a stopwatch.

In the article they also write about emission from signal lines. Electronic designers have been working for decades on such problems to avoid interference with other devices and to satisfy regulatory requirements. Simple layout changes of the PCB can achieve this at marginal cost. On the other hand electromagnetic emissions can't be completely avoided and an attacker can use more sophisticated measurement and analysis methods, but a good PCB design can drive the costs for such an attack significantly up. Therefore EMI-engineering should be mandatory for the development of security hardware.
