Abstract:
Abstract It is obvious that information is remarkably important and valuables however, it is exposed to danger of theft, hacking, abuse and violation every now and then. Therefore, protection of such valuable information has the attention of all – organization, firms and individuals. Recently, cyber and crimes had developed which exposes information to extreme threat. The dissemination of systems information crimes have spread in industrial countries and Saudi Arabia is no exception due to the development that the country has witnessed and its growing involvement of information systems in different economic and scientific fields besides the increasing use of the internet.Information protection has become crucial and this can be approached through a variety of means and methods. The most important of these means and methods is encryption. Encryption uses different algorithms [2]. This present paper will tackle two algorithms, namely: Data Encryption Standard (DES) and Public Key Algorithm (PKA). The paper also presents how the two algorithms operate, discuss the shortcomings of each of them and then proposes a model which merges the two algorithms in the stage of key generating to come up with solutions for their shortcomings. Keywords: Encryption, Decryption, DES, PKA, RSA, Plain text, Cipher text, Combination.
