For security of data communication over public network, various cryptographic methods and algorithms are used. The cryptographic methods are divided as symmetric cryptography and asymmetric cryptography method. Same key is used for encryption as well as for decryption in symmetric cryptography methods unlike asymmetric cryptography method. The problem with symmetric cryptography method is that participants should share a secret key among each other in a secure way which is difficult. Asymmetric cryptography method overcome the issue of key sharing by using 2 keys.This paper presents the implementation and comparison of AES, Chaffing &Winnowing, Diffie Hellman Key Exchange Algorithm and Hybrid Cryptographic Algorithmsfor variable concurrency for fixed time. Our Aim is to compare the cryptography algorithm to calculate the performance evaluation among selected algorithm by calculating encryption time, decryption time and throughput for each algorithm to identify which algorithms outperforms others in term ofparameters decided for comparison. This paper is organized as follows: Section 2 of this paper describes ProposedArchitecture Section 3 highlights parameters used for the comparison evaluation. Section 4 describes experimental setting and data required for the Evaluation, results are shown in section 5 and Section 6 presents conclusion of the research work.
