AN APPROACH TO IMPROVE THE COMPLEXITY OF EL-GAMAL CRYPTOGRAPHIC ALGORITHM AND ITS SIMULATION

In this paper, we analyzed the principle and techniques of EL-Gamal and based Threshold Cryptography using GMP tool. A novel approach is proposed to provide the efficient performance and security. Using GMP tool, the data can be encrypted and decrypted based upon the security and complexity of cryptographic algorithm. This paper proposes on the scheme based on El-Gamal based Threshold algorithms and their simulation results proves the efficiency and security of the network. The result shows that the authentication and security given by El-Gamal algorithm is enhanced by its integration of threshold cryptographic schemes.
