摘要：RSA cryptosystem is the most commonly used public key cryptosystem. It is the first public key cryptosystem. The strength of this cryptosystem is based on the larger key size. There are many algorithms and variants of RSA. In RSA, encryption keys are Public, but decryption keys are not, so only the person with the correct decryption key can able convert cipher into decipher or encrypted message. The keys must be making in such a way that the decryption key may not be very easily deduced from the public encryption key. In this paper, we have proposed a implementation of some modern variants of the RSA algorithm. In our proposed cryptosystem, the encryption is faster in comparison to current RSA Cryptosystem. Also our proposed cryptosystem is more secure against low decryption exponentiation attack, because we are using a large value of d and in our proposed cryptosystem computation of the plain text from the cipher text are done by applying the Fermat’s theorem.
