Cryptography has come up as a solution which plays a vital role in information security system against malicious attacks. This security mechanism uses some algorithms to scramble data into unreadable text which can be only being decoded or decrypted by party those possesses the associated key. Asymmetric encryption techniques i.e. Rivest-Shamir-Adelman (RSA) and NTRU algorithms have been implemented. Avalanche effect was analyzed on this encryption technique. Avalanche effect means a change in one bit of the plaintext or one bit of the key should produce a change in many bits of the cipher texts.
