摘要: This paper describes the technique of Dummy Rounds as a countermeasure against DPA in hardware implementation round-based ciphers. Its principle is inspired by several well-known countermeasures used Hiding and Dynamic Reconfiguration well software implementations cycles, Random order execution or time. Being based on dynamic reconfiguration, this method combines hiding power consumption with In work we also discuss amount randomness available for control computation.
