Abstract

Objectives: To find which cryptographic algorithm would produce fine result. Methods: This survey mainly focuses to an analysis of symmetric cryptographic algorithms DES, 3DES, AES, RC4 in the basis of encryption/decryption time, memory and throughput. Here .net platform has been used to simulate the results to find the best algorithm for text file transmission. Findings: Simulation tests are conducted for text files in different file sizes. These text files are given as input to each specified algorithms and calculated the results. The tests have taken seven different sizes of text files. How the above algorithms affect system resources while encryption and decryption process are explained in this project. The key focus of the project is to find the performance of the algorithms. Applications/Improvements: If the algorithm shows lowest performance in throughput/memory/encryption time, new algorithm has to be developed to give better performance with all of these metrics.
