WebRSA proof of correctness. RSA is one of the most popular public-key cryptographic algorithm today, this article explains the proof of correctness of the RSA algorithm using two simple mathematical theorems: Chinese remainder theorem and Fermat's little theorem. Lang/Tech: RSA WebDec 3, 2010 · In short, this paper explains some of the maths concepts that RSA is based on, and then provides a complete proof that RSA works correctly. We can proof the correctness of RSA through combined process of encryption and decryption based on the Chinese Remainder Theorem (CRT) and Euler theorem.
