Implementation and comparison of hybrid encryption model for secure network using AES and Elgamal

Sonia Rani, Harpreet Kaur


Cryptography is a concept to protect network and data transmission over network. Data Security is the main aspect of securing data transmission over unreliable network. Cryptography is a method of storing and transmitting data in a secret form so that only those for whom it is intended can read and process it. There are two types of cryptography algorithms such as symmetric key cryptography and asymmetric key cryptography. At present there are various types of cryptographic algorithms provide high security to information on networks, but they also have some drawbacks. To overcome the drawbacks of these algorithms, we propose a new hybrid cryptographic algorithm in this paper. The algorithm is designed using combination of two cryptographic algorithms AES and Elgamal. Analyse and compare the performance of existing and proposed algorithm on parameters security, encryption time, decryption time and throughput. This new hybrid cryptographic technique has been designed to decrease encryption and decryption time and increase throughput. In this work core java + swing in NetBeans IDE 7.0.1 jdk 8.0. is used. Implementation and performance analysis of proposed model done by JAVA. Results shows the Hybrid model perform better than AES and Elgamal individually.

Keywords: Cryptography, AES, Elgamal and Hybrid AES and Elgamal
