Analysis of brute-force attack in UES over DES

Abstract

Data transferring by means of internet has acquired a considerable significance in the recent times which in turn demands interchanging of enormous quantities of information on frequent basis. Vital information always looks for a enhanced stage of protection where cryptography is one such principle which is reliable enough to arrange the same for that data. A new cryptosystem “Ultramodern Encryption Standard (UES)” was proposed by us in our earlier research articles in order to provide a considerable level of protection. Brute-force attack is the most dangerous one where every cryptosystem is expected to with stand over this attack. In this paper we depicted the quality the proposed cryptosystem UES against brute-force attack via the estimated cracking time of the keys used and the experimental results projected here are evident that UES can with-stand to this attack in a better way when compared to the existing Data Encryption Standard-DES.
