SD-AREE-I Cipher: Amalgamation of Bit Manipulation, Modified VERNAM CIPHER & Modified Caesar Cipher (SD-AREE)
This paper presents a new combined symmetric key cryptographic technique, which is generally an amalgamation of Bit Manipulation, generalized Modified Vernam Cipher, Single Bit Manipulation and Modified Caesar Cipher. The technique proposed here is basically an advanced and upgraded module of SD-AREE cryptographic method, which is based on Modified Caesar Cipher along with Bit Manipulation and ...
متن کاملComparative study between stream cipher and block cipher using RC4 and Hill Cipher
Sometimes the information, which is transferred during the communication, is very much confidential which is needed to be secure. For securing the information various encryption algorithms like DES, BLOWFISH, RC4 etc., are used. Our aim in this paper is to find the two keys using cryptanalysis method, that is used for encrypting the information transferred during communication by using the Meet...
متن کاملThe Chameleon Cipher-192 (CC-192) - A Polymorphic Cipher
The Chameleon Cipher-192 is a polymorphic cipher that utilizes a variable word size and variable-size users key. In the preprocessing stage, the user key is extended into a larger table or bit-level S-box using a specially developed hash-function. The generated table is used in a special configuration to substantially increase the substitution addressing space. Accordingly, we call this table ...
متن کاملCOBRA: A Parallelizable Authenticated Online Cipher Without Block Cipher Inverse
We present a new, misuse-resistant scheme for online authenticated encryption, following the framework set forth by Fleischmann et al. (FSE 2012). Our scheme, COBRA, is roughly as efficient as the GCM mode of operation for nonce-based authenticated encryption, performing one block cipher call plus one finite field multiplication per message block in a parallelizable way. The major difference fr...
متن کاملAn Improvement of RC4 Cipher Using Vigenere Cipher
This paper develops a new algorithm to improve the security of RC4. Given that RC4 cipher is widely used in the wireless communication and has some weaknesses in the security of RC4 cipher, our idea is based on the combination of the RC4 and the poly alphabetic cipher Vigenère to give a new and more secure algorithm which we called VRC4. In this technique the plain text is encrypted using the c...
