In the rapid development of contemporary information technology, security has become important technique in many applications including Virtual Private Network (VPN), electronic commerce, secure internet access etc. The security of public key encryption such as RSA scheme relied on the integer factorization problem. The security of RSA algorithm is based on a positive integer n, because each transmitting node generates pair of keys such as public and private. Encryption and decryption of any message depends on positive integer n.
