Abstract: Aspects of the present disclosure involve a method and a system to perform the method to obtain a cryptographic output of a plurality of rounds of a cipher, by performing a plurality of modified rounds of the cipher, each of the modified rounds computing an unmasking transform, an operation of a respective round of the cipher, and a masking transform, the unmasking transform being an inverse of the masking transform of a previous round of the cipher.

Abstract: A value corresponding to a physical variation of a device may be received. Furthermore, helper data associated with the physical variation of the device may be received. A result data may be generated based on a combination of the value corresponding to the physical variation of the device and the helper data. An error correction operation may be performed on the result data to identify one or more code words associated with the error correction operation. Subsequently, a target data may be generated based on the one or more code words.
