Understanding the Concept of Data Encryption in Network Security: Review of Types, Algorithms and Methodologies

Abstract

Data encryption is the process of security method which is also used to provide security in network. There are many security methods available. Data encryption is the latest and most commonly used security method in order to protect the data and sensitive information of the user. It depends upon the technical team to choose the best network security method so that they are able to protect the data and information of the organisation. The technical team need to understand the business goals and objectives and based upon the type of data and information of the organisation, should select the best and efficient network security methods which is also one of the major challenges of the team. The objective of data encryption is to encrypt the data in such a way that it is not easily understood by the anyone else other than the person who is authorised to have access and also have the key to access it. It is one of the best methods of data encryption. The paper will discuss the importance of data encryption, the methodologies available and also its benefits as well as challenges.
