The Literature Review on The Role and Significance of Cryptography for Network Security in Current Scenario

Abstract

As the internet has gotten more integrated into our daily lives and has grown exponentially over the last several decades, data security has become a major issue for everybody connected to the internet. Data security ensures that only the intended recipients have access to our information and prohibits any data modification or manipulation. Various techniques and approaches have been developed to reach this level of security. Cryptography is described as a set of techniques for encrypting data using specified algorithms that render the data unreadable to the naked eye unless decoded using procedures predefined by the sender. We cover some of the most recent research in the fields of cryptography and network security in this article. The security vulnerabilities of existing as well as upcoming technologies in the field of Computer Networks are discussed in these research articles. We bundle the articles together based on their content and categorise the research subjects based on their implementation throughout the seven layers of the well-known OSI reference model. In the interest of brevity, the main purpose for each research study is outlined, and the proposed solution is stated simply.
