A Block Cipher Generation Using Color Substitution

A Block Cipher Generation Using Color Substitution

The most powerful and common approach to countering the threats to network / information security is encryption [1]. Even though it is very powerful, the cryptanalysts are very intelligent and they were working day and night to break the ciphers. To make a stronger cipher it is recommended that to use: More stronger and complicated encryption algorithms, Keys with more number of bits (Longer ke...

A New Framework for Scalable Secure Block Cipher Generation using Color Substitution and Permutation on Characters, Numbers, Images and Diagrams

The aim of our research is to develop a new framework for secure block cipher generation using color substitution and permutations on alphanumeric letters, symbols, images, diagrams or any kind of text. To transfer the keys from source to destination we have used RSA public key algorithm and for encryption / decryption of the information, we have used our invented „play color substitution‟ algo...

A Block Cipher Algorithm for Multimedia Content Protection with Random Substitution using Binary Tree Traversal

Many people consume multimedia content (images, music, movie) on portable devices like DVD player, MP3 player, Portable Multimedia Player and also through Internet. Problem statement: The conventional algorithms such as DES and AES cannot be used directly in multimedia data, since multimedia data are repeatedly have high redundancy, large-volumes and require real-time operations, such as displa...

A Traceable Block Cipher

In this paper we propose a new symmetric block cipher with the following paradoxical traceability properties: it is computationally easy to derive many equivalent secret keys providing distinct descriptions of the same instance of the block cipher. But it is computationally difficult, given one or even up to k equivalent keys, to recover the so called meta-key from which they were derived, or t...
