Abstract
Systems and methods for performing cryptographic data processing operations employing non-linear share encoding for protecting from external monitoring attacks. An example method includes: receiving a plurality of shares representing a secret value employed in a cryptographic operation, such that the plurality of shares includes a first share represented by an un-encoded form and a second share represented by an encoded form; producing a transformed form of the second share; and performing the cryptographic operation using the transformed form of the second share.
