A Review of Encryption Methods for Secure Data Communication

We are living in the new era of information, and information is an important aspect of our living. So, the need of security is to ensure that our information remains confidential and only authorized users can access it, and ensuring that no unauthorized user has changed our information, so that it provides full accuracy and efficiency. To be secured, information needs to be hidden from unauthorized access i.e. confidentiality and protected from unauthorized change and also available to an authorized entity when it is needed.
