ABSTRACT
This paper gives a brief summary of cryptography, where it is applied and its usage in various forms. Cryptography is a way of safeguarding the crucial data from unauthorized access. It has emerged as a secure means for transmission of information. It mainly helps in curbing intrusion from third party. It provides data confidentiality, integrity, electronic signatures, and advanced user authentication. The methods of cryptography use mathematics for securing the data (encryption and decryption).
Keywords: Cryptography, Data Confidentiality, Integrity, Electronic signatures, Authentication, Encryption, Decryption
1. INTRODUCTION
Information security plays a pivotal role during internet communication in today’s era of technology. It is tremendously important for people committing etransactions. For naïve people it may seem to be not that necessary orincreased security may provide comfort to paranoid people but the truth is that it is absolutely essential when communication is carried between tens of millions of people daily. There are various cryptography methods that provide a means for secure commerce and payment to private communications and protecting passwords. Cryptography is necessary for secure communications; it is not by itself sufficient. The reader of this paper will find variants of cryptography and their applications. This paper has two major purposes. The first is to provide some real examples of cryptography in use today. The second is to provide tabular summarization and conclusion. Curious readers should check out some of the web pages and pdf in the bibliography below for further detailed — and interesting! — background information.
