PrasathSrinivasan Sushmitha Algorithm for String Encryption and Decryption

Abstract Security is essential for communication of messages, data, and private information. Security threats and vulnerabilities increases rapidly due to the wide usage of wireless medium for data transmission. The sensitive data and private information transmitted across internet can be accessed and altered by the intruders. The security algorithms are important to ensure the communication of messages without unauthorized access and modification as well as to achieve data security. This proposed work is the development of novel cryptography suitable for encryption of text messages. This proposed algorithm encrypts the input string into ciphertext through 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 the theft and fraud in online money transactions, securing the email messages, file encryption, securing the web information, ensuring data confidentiality across internet, assuring data security in remote access, securing the patients information transmitted across wireless networks, enabling secure communication of country’s border information, preventing the credit card fraud, securing the industrial continuous varying process parameters, encryption of whatsapp messages, and securing the individual’s private information.
