INTRODUCTION One important, yet practical, application of complexity theory is cryptography. It has become one of the main tools for privacy, trust, electronic payments, and other forms of security. It is no longer just a military tool and the advantages it provides should be used to the fullest extent. This paper will discuss basic terminology and main methods of cryptography. BASIC TERMINOLOGY Cryptography is the science of scrambling text so that no one can read …showed first 75 words of 2541 total…

CONCLUSION It is clear that information security, generally cryptographically speaking, is one of the largest problems faced by our modern society today because it touches almost every aspect of private and commercial life. It is time that cryptography no longer be treated as a military weapon, but as an advantageous tool that can be used to provide security for even the individual user in our ever advancing modern world.
