    The globalization and the trend towards a knowledge-based economy emphasize the importance of using Information and Communications Technology (ICT) and elearning concepts in education. Currently many countries trying to adapt ICT in many aspects of their education systems. But in many cases, we hear that those attempts become failures due to various reasons such as poor infrastructure, lack of basic ICT knowledge, high cost in implementing the system for the first time in a country etc. This literature review focuses on how we can use ICT successfully in education. As our research topic is Effectiveness of using ICT in education, we studied some of the current systems used in various countries, the pros and cons of those available systems and the solutions they provided for the problems they have faced so far. Our view on those problems and solutions are discussed at the latter part of this paper.

    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)
