Combining Cryptographic Primitives According to Security Metrics and Vulnerabilities in Real Systems

Abstract

There are so many applications and data that flow during our daily activities, either personal or institutional ones. Also the companies and business do transactions or their real operations through the Web and other Internet facilities. Security breaches are costing individuals or companies millions so information security has to be a major priority. There are several forms of security technology available, but encryption is one that everyday computer users should know about. Encryption and the performance of cryptographic algorithms are variable according to implemented platforms, software and hardware components or application scenarios. According to specific security metrics and requirements we have to use algorithms even in a combined manner that should be more efficient and best suited. Multi-level encryption and hybrid encryption should be a fine solution to protect our data. In this paper we specify the security musts according to Alfa software using cryptographic algorithms.
