The need of security has turned into a vital area of research in domain of computer science. The evolution of side channel attacks has challenged the vulnerability of almost all the symmetric and asymmetric cryptographic techniques available worldwide. This has raised the urgency in designing mitigation techniques against such volatile attacks. Power analysis attacks, which is the most popular side channel attacks has proved to be a challenge for most of the common cryptosystems like AES, DES, RSA, ECC, etc. MIST is an algorithm which was designed for computing exponentiation. As the most important operation of RSA is the modular exponentiation for encryption and decryption, MIST can play an important role in designing modified RSA to resist power analysis attacks. We have extended our work CRT-RSA, which is more widely used in computation. The analysis results shows that modified RSA can perform better in computing RSA specially when CRT is has been used.
