Chaos-Based Cryptography: Text Encryption Using Image Algorithms

Currently, chaotic cryptography is mainly concentrated on image encryption. Once-popular stream-encryption algorithms, e.g., textual data, are now rarely considered. This article studies how image-encryption algorithms can be used to encrypt text. The proposed approach this problem consists of two stages: in the first stage, text message intended for encryption into an image; second step, selected algorithm used. An example illustrates efficiency method. In addition, presents measures analysis that confirm security obtained cipher-image, such as entropy (value close 8), correlation adjacent pixels (values 0), or related differential cryptanalysis. method offers a new look at using chaos, by applying already known from literature.
