<p>A method to protect computational, in particular cryptographic, devices having multi-core processors from DPA and DFA attacks is disclosed herein. The method implies: Defining a library of execution units functionally grouped into business function related units, security function related units and scheduler function related units; Designating at random one among the plurality of processing cores on the computational device to as a master core for execution of the scheduler function related execution units; and Causing, under control of the scheduler, execution of the library of execution units, so as to result in a randomized execution flow capable of resisting security threats initiated on the computational device.</p> |
