摘要：Achieving higher level of security in message transfer over networked environment and the efficiency ofa cryptographic algorithm is based on its time taken for encryption / decryption and the way it produces different ciphertext from a clear text. The RSA, the widely used public key algorithm and other public key algorithms may notguarantee that the cipher text is fully secured. As an alternative approach to handling ASCII characters in thecryptosystems, a vertex magic total labeling of complete graph is thought of in this work. It attempts to enhance theefficiency by providing add-on security to the cryptosystem. This approach will increase the security due to itscomplexity in encryption because it deals with the VMTL formation that cannot be easily traced. Here, encryption /decryption is based on numerals contained in VMTL table rather than ASCII values. This proposed work providesanother layer of security to any public key algorithms such as RSA, ElGamal etc. Since, this model is acting as awrapper to a public key algorithm; it ensures that the security is enhanced. Further, this approach is experimented in asimulated environment with 2, and 4 processor.
