EM emissions can be a rich source of leakage for side-channel analysis of cipher implementations. In this paper, we describe a set of novel countermeasures based on dynamic spatial relocation and dynamic mappings, and validate the protection provided by them against EM attacks. The countermeasures improve significantly the security of the circuit.
