A Survey on Cryptographic Techniques for Network Security

Cryptography plays a vital role in information security system against various types of attacks. This security mechanism uses some algorithms to scramble data into unreadable text which can be only being decrypted by party those possesses the associated key. The two important characteristics that identify and differentiate encryption algorithms from another are their capability to secure the protected data against attacks and their speed and effectiveness in securing the data. Cryptography is method that provides the security mechanism in timely driven fashion. Main objective of this paper is to compare the most commonly used algorithms for data encryption. Main concern in this paper is the performance analysis of different algorithms under different settings.
