SD-AREE: A New Modified Caesar Cipher Cryptographic Method Along with Bit-Manipulation to Exclude Repetition from a Message to be Encrypted
This addresses security vulnerabilities in encryption for applications like secure communication, but it appears incremental as it builds on existing cipher methods.
The authors tackled the problem of cryptographic attacks exploiting repetitive terms in messages by proposing SD-AREE, a modified Caesar cipher with bit-manipulation that removes repetitions, making it nearly impossible to retrieve the original message from the encrypted one.
In this paper the author presents a new cryptographic technique to exclude the repetitive terms in a message, when it is to be encrypted, so that it becomes almost impossible for a person to retrieve or predict the original message from the encrypted message. In modern world, cryptography hackers try to break a code or cryptographic algorithm or try to retrieve the key, which is needed to encrypt a message, by analyzing the insertion or presence of repetitive bits / characters (bytes) in the message and encrypted message to find out the encryption algorithm or the key used for it. So it is must for a good encryption method to exclude the repetitive terms such that no trace of repetitions can be tracked down. For this reason we apply SD-AREE cryptographic method to exclude repetitive terms from a message, which is to be encrypted. In SD-AREE method the repetitive bits / characters are removed and there is no trace of any repetition in the message.
