Abstract
Nowadays the modern world depends on connections through the internet brings different teams together. The essential components of communication are sender, medium, and receiver. Data transmission over the internet is not possible without any encryption method due to security issues. Different types of areas like corporate sectors, banking sectors, government sectors, and many other sectors share their data through the internet. Hackers always try to attack the transmitted data and try to recover the data. Various techniques are developed for providing data security. Cryptography is used for the safe transmission of data. Encryption is done at the sender side in cryptography, and decryption is done at the receiver side. In the encryption technique, Caesar cipher is one of the best examples. The analysis of Basic Caesar cipher, Delta formation Caesar cipher, and XOR Caesar cipher is done based on many parameters like Avalanche Effect, Frequency Test, and Brute force attack. The authors of this paper have tried to modify the caesar cipher method, which produces ciphertext that can be read. After that with the new ciphertext that can be read, then cryptanalysis not suspicious of the ciphertext.
