Enhancing Cloud Security Using VIJANA Cloud Data Jacket Protocol

Abstract

In the cloud, the risks to sensitive data are greater than ever before. Cloud attacks have long been an important problem that requires a lot of research to be done to design security solutions that truly protect the user’s data. It is essential to transmit private data securely by encapsulating from unauthorized users. The better way to protect the data transmitted through the cloud from a malicious third party is to scramble the data before transmission. This paper sets out to contribute to the area of cryptography by developing a novel encipherment technique that will conceal the confidential data sent through the cloud by obtaining a polyalphanumeric substitution cipher. The encryption/decryption of cloud data is performed based on the VIJANA tableau by using the substitution method. The mathematical background of the cryptographic method and key generation is given. This technique becomes more secure when it works along with the key agreement method which is based on a discrete logarithm. Four new algorithms for key contract, key generation, encryption, and decryption are created and implemented. Encrypt/decrypt results achieved by applying the technique are shown with sample data. The VIJANA encipherment technique is justified to be a true security solution to ensure privacy of cloud data communication with cryptanalysis done.
