Abstract

Security is essential for communication of messages, data, and private information. Security threats and vulnerabilities increase rapidly due to the wide usage of wireless media for data transmission. Intruders can access and alter sensitive data and private information transmitted across the Internet. Security algorithms are important to ensure secure communication without unauthorized access or modification. This work proposes a novel cryptography scheme for encrypting text messages. This proposed algorithm encrypts the input string into ciphertext through a series of mathematical operations. The inverse operation of encryption is performed at the receiver to obtain the original string from the ciphertext. This proposed cryptography can be utilized for preventing theft and fraud in online money transactions, securing email messages, file encryption, securing web information, ensuring data confidentiality across the internet, assuring data security in remote access, securing the patients' information transmitted across wireless networks, enabling secure communication of the country’s border information, preventing credit card fraud, securing the industrial continuous varying process parameters, encryption of WhatsApp messages, and securing the individual’s private information.
