Apply of Design Patterns and Encryption Algorithms in Information Systems

Abstract

The paper discusses to the application of Design Pattern (DP) and encryption algorithms in Information Systems (IS) in order to protect Information Security (ISec). The paper presents attack vectors, protection approaches and the ISO standard, generalizes classification of DPs, which are used in IS to protect ISec, compares encryption algorithms. The present paper proposes an approach for the use of DPs and algorithms for encrypting and decrypting data, using the algorithm Secure Hash 256 (SHA256), as well as authentication of the SMTP (Simple Mail Transfer Protocol).
