Protection against power analysis attacks

An electronic circuit is password processing, comprising a first combinatorial logic, carried out from the configuration and data-in the first group of logical operation and generating output data, wherein the output data with a wherein the functional relation of data-, further - comprising at least comprises a second combinatorial logic, end of the second group of logical operation and generating output data by an embedded-type are the same data-, wherein the output data is provided with the same a relation of data-, wherein the first group of logical operations is different from the second group of logical operations; the electronic circuit is formed of a configuration at least comprises a claimsThe first combinatorial logic and second combinatorial logic's set dynamic and a combinatorial logic, which is used to the data-in driving logic operation and generating output data.
