METHOD FOR PRODUCING A DPA-RESISTANT LOGIC CIRCUIT

摘要

In an application-specific integrated circuit (ASIC), a description of the logic circuit is formulated in a hardware description language and then converted into a description of a corresponding physical circuit, i.e., into a netlist, using a conversion program, i.e., a synthesis tool. The description at least largely consisting of standard cells. During the conversion process, the standard cells which are used in the netlist are replaced with standard cell versions which have a correspondingly balanced power dissipation. Spying on a mode of operation of the circuit by analyzing a power consumption of the circuit is thus advantageously hindered or prevented, in particular in security-relevant circuits.
