Summary:Methods and systems are provided for securing an integrated circuit device against various security attacks, such as side-channel attacks. By limiting the number of different challenge vectors that can be combined with a critical variable of an encryption operation, it becomes more difficult to create enough side channel measurements to successfully perform statistical side-channel analysis.
