Naïve hardware implementation of encryption modules can cause leakage about the secret information. Attackers can use this information to extract the secret key. This approach is known as side channel attack (SCA). An example of such attacks is differential power analysis (DPA), which uses a number of traces of power consumption of the encryption device. One of the proposed methods to deal with such attack is using dual rail logic. In previous implementations based on a dual rail logic, symmetric complementary mapping with the cross coupling and pre-charging is being used. This method has relatively high delay and cost; however, significant increase in the level of security can be achieved....
