“…The RC6 has three variable parameters: size of the word (w) in bits, number of rounds (r) which is a non-negative integer and length of the secret key in bytes (b) that is used in both encryption and decryption phases [21], [23], [26], [27]. Based on the values of such parameters, the RC6 is precisely identified as RC6-w/r/b.…”

“…Visual inspection is a major indicator in evaluating the quality of encrypted images. If the image features are hidden well, this means that the utilized image cryptosystem is good in performance [15], [16], [20], [23], [25]. Moreover, it is known that visual examination does not detect the full relation between the original and the encrypted images.…”

Recently, massive research works have been accomplished for augmenting privacy and security requirements for cybersecurity applications in wireless communication networks. This is attributed to the fact that conventional security processes are not appropriate for robust, efficient, and reliable multimedia streaming over unsecure media. Therefore, this paper presents an efficient color image cryptosystem based on RC6 with different modes of operation. The proposed cryptosystem is composed of two phases: encryption and decryption. The encryption phase starts by decomposing the color plainimage with few details into its RGB components, which in turn, are segmented into 128-bit blocks. These blocks are then enciphered using RC6 with an appropriate mode of operation. After that, the corresponding enciphered blocks of RGB components are multiplexed for constructing the final cipherimage. This scenario is reversed in the decryption phase. The performance of the proposed cryptosystem is gauged via simulation using a set of encryption quality metrics. The simulation results reveal that the proposed cryptosystem with cipher block chaining (CBC), cipher feedback (CFB), and output feedback (OFB) modes can efficiently and effectively hide all information of the color images with few details even in the presence of some input blocks with similar data. On the other hand, the results show that the electronic codebook (ECB) mode is not effective at all in hiding all details of images. Finally, the obtained results ensure the applicability of the proposed cryptosystem and its efficiency in encrypting images in terms of security, encryption quality, and noise immunity.

Information technology that is increasingly developing today must be balanced with information security. Good security can minimize the possibility of information being stolen by cryptanalysis, one way is by applying cryptographic techniques. Vigenere Cipher is a key symmetry algorithm that uses a substitution technique that uses two letters encoding the original message. Vigenere cipher and one time pad have disadvantages because they use short keywords and their use will be repeated. The key expansion used is part of the RC6 encryption algorithm combined with Vigenere and One time pad to cover the weaknesses of the algorithm. The purpose of this study is to produce new variations with the modification of the vigenere cipher algorithm and one time pad by adding a key expansion process and tested using the avalance effect. Test results conducted based on modifications can achieve a high level of avalance effect which is 51.76%

Cryptography is one of the most popular methods in data security by making data very difficult to read or even unreadable. One of the well-known techniques or algorithms in cryptography is Vigenere Cipher. This classic algorithm is classified as a polyalphabetic substitution cipher-based algorithm. Therefore, this algorithm tends to only handle data in text form. By this research, a console-based application has been developed which is made from PHP programming language to be able to encrypt and decrypt digital image media using Vigenere Cipher. The encryption process is done by first converting a digital image into a base64 encoding format so that the encryption process can be carried out using the tabula recta containing the radix-64 letter arrangement used for base64 encoding. Conversely, the decryption process is carried out by restoring the encrypted file using radix-64 letters, so we get the image file in the base64 encoding format. Then, the image with the base64 encoding format is decoded into the original file. The encryption process took less than 0,2 seconds and 0.19 seconds for the decryption process and 33.34% for average file size addition on the encrypted file from the original file size. Testing on ten different images with different sizes and dimensions showed a 100% success rate which means this research was successfully carried out.
