Generates two keys from a single key is used to provide enhanced security. We also increase the domain of characters whichĬaesar cipher Algorithm can encrypt by including all ASCII and extended ASCIIĬharacters in addition to alphabets. To increase the strength of this classicalĮncryption technique we use the concepts of affine ciphers, transpositionĬiphers and randomized substitution techniques to create a cipher text which is Modified approach and expanded version for Caesar cipher using knowledge of This paper, we contribute in the area of classical cryptography by providing a However, with the advent of powerfulĬomputers there is a need for increasing the complexity of such algorithms. Read moreĬaesar cipher is an ancient, elementary method of encrypting plain text After that with the new ciphertext that can be read, then cryptanalysis not suspicious of the ciphertext. The authors of this paper have tried to modify the caesar cipher method, which produces ciphertext that can be read. 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. In the encryption technique, Caesar cipher is one of the best examples. Encryption is done at the sender side in cryptography, and decryption is done at the receiver side.
Cryptography is used for the safe transmission of data. Various techniques are developed for providing data security. Hackers always try to attack the transmitted data and try to recover the data. Different types of areas like corporate sectors, banking sectors, government sectors, and many other sectors share. Data transmission over the internet is not possible without any encryption method due to security issues. The essential components of communication are sender, medium, and receiver. Nowadays the modern world depends on connections through the internet brings different teams together. With the ciphertext that can be read, then the cryptanalyst not suspicious of the message so that the cryptanalyst does not attempt to solve the ciphertext.
From the test results obtained ciphertext that can be read. However, there are some alphabet consonants are not replaced, this is because the frequency of the alphabet is rarely used in an Indonesian text.
Caesar cipher modification is done by replacing the alphabet into two parts, the vocals were replaced with the alphabet vocal too, and the consonant alphabet was replaced with a consonantal alphabet. With the ciphertext that can be read, then cryptanalysis not suspicious of the ciphertext. In this paper, the authors modify the Caesar cipher method that produces ciphertext that can be read. While the use of steganography owner of the information is difficult to determine the method or pattern to be formed in composing the message that will be hidden. Thus, the cryptanalyst attempts to break the encrypted message. This is possible because usually a text message unreadable gives someone suspicion that the text message contains a certain meaning for the owner of the message. On the other side, it turns out the use of cryptography can often be solved / translated by another person or cryptanalyst. However, both methods have the same goal, namely the attempt to conceal the message. In a secret message, cryptography is more directed to the encrypted message while steganography is more directed at the hidden message.
