Modern cryptography: approaches and attacks

Abstract

Information is in many forms and it is everywhere. Information is to be exchanged. At present communication systems are well developed and widely used There arise the issues regarding the Security Measurements The ‘security impose' tends to trade off with communication speed. Cryptography is the main methodology used in security enforcement over information exchanges. With time the requirements change and so does the approaches for cryptography. With fresh approaches there emerge new attacks. This paper tends to analyze the generalized approaches and attacks over time and it is restricted (only) to the Computer Era (computer and internet related cryptography)
