Cryptography is used to make data and information transmission and computational systems secure over the networks by using mathematical and scientific techniques. The cryptographic algorithm should fulfil the conditions of authentication, confidentiality, integrity and reliability. In today’s era, where digital communication and data storage is increasing day by day and the data leakage, breaches and attacks are continuously rising. The increase in need of strong and secure cryptography algorithms to protect user information that ensures the integrity and confidentiality of data. The existing symmetric cryptographic algorithms like AES or DES, can provide strong security but they have very complex implementations and requires high computational resources. The aim of this paper is to provide a study for the research done in the field of cryptography, cryptographic techniques and to propose and developed a light weight symmetric cryptographic algorithm using different fundamental cryptographic techniques that is secure and fulfils the conditions of authentication, confidentiality, integrity and reliability.
