Correlation Power Analysis Attack on the Ping Pong-128 Key Stream Generator

Power analysis attack on cryptographic hardware device aims to study the power consumption while performing operations using secrets keys. Power analysis is a form of Side Channel Attack (SCA) which allows an attacker to compute the key encryption from algorithm using Simple Power Analysis (SPA), Differential Power Analysis (DPA) or Correlation Power Analysis (CPA). The theoretical weaknesses in algorithms or leaked information from physical implementation of a cryptosystem are usually used to break the system. In this paper proved the weakness of PingPong-128 key stream generator which increased outputs key stream of specific non-linearity by adding mutual clock-control structure to previous summation generator through Correlation power analysis attack.
