Mathematical investigation of cryptographic functions and operations used in cyber attacks

Abstract

Cryptography has always been a corner stone of security domain. Different security services such as confidentiality, integrity, availability, authentication, nonrepudiation and access control, are provided by a number of cryptographic algorithms including block ciphers, stream ciphers and hash functions. Until to day, different operations and functions used in cryptography. In this paper, I have as mathematical survey of cryptographic functions and operations of the algorithms used in cyber attacks. Then, time series analysis of used algorithms have perform and their fruquency of use have determined. This investigation will help for identifying different operations and functions in cryptographic algorithms. © 2017 IEEE.
