Comparative study of Cryptography Algorithms
Main Article Content
Abstract
The need for improved techniques ensuring secure transmission and storage of information has been ever increasing. This
has led to keen interest in the field of cryptography across the globe.The focus of research and development in cryptography has been
directed towards meeting security requirements. The essence of this field is the optimal realization of encryption algorithms in
software or hardware or a combination of both. Encryption algorithms transform messages by addingsome cryptographic protection,
such as confidentiality, authenticity or integrity to them. These algorithms employ one or more keys that are cryptographic variables
used to control the algorithm and provide security against attackers. This paper deals with a comparative study of encryption
algorithms along with their applications in real world scenario.
