A COMPARISON OF CRYPTOGRAPHIC ALGORITHMS: DES, 3DES, AES, RSA AND BLOWFISH FOR GUESSING ATTACKS PREVENTION

 

 

Abstract

Encryption is the process of encoding information or data in order to prevent unauthorized access. These days we need to secure the information that is stored in our computer or is transmitted via internet against attacks.  There are different types of cryptographic methods that can be used. Basically, the selecting cryptographic method depends on the application demands such as the response time, bandwidth, confidentiality and integrity. However, each of cryptographic algorithms has its own weak and strong points. In this paper, we will present the result of the implementation and analysis that applied on several cryptographic algorithms such as DES, 3DES, AES, RSA and blowfish. Also, we will show the comparisons between the previous cryptographic techniques in terms of performances, weaknesses and strengths.
