Estimation of Various Parameters for AES, DES, and RSA

Securing the data from unauthorized access is turn out to be a major challenge nowadays. Large volume of data is available in every field for which the security is most crucial. To secure the data, the security experts in last few decades implement various techniques. The main domain, which provide data security, is known as cryptography. This provide security to data against the unauthorized access. Encryption and decryption are two basic terms in cryptography. With the evolution of techniques and intelligence, the chances of getting unauthorized access on data are increased with multifold scenario. To overcome with this, the researchers use various security algorithms. In this research paper, a practical analysis between AES, DES, and RSA is implemented to assess their performance parameters in respect of their space complexity, encryption time, and throughput. Experiments are carried out on various type of data files so that the performance of three can be analyzed.
