Discrete or computerized chaotic systems are being extensively studied for various applications in cryptography. However, the security of them is not yet convincing to be used in real applications. This paper is proposing modifications to chaotic synchronization process, which have been studies a lot as a potential replacement to LFSR's. Here we are(More)
A relatively new domain in the area of cryptoanalysis is the use of disorderly or chaotic systems to encrypt and decrypt data. The aim of this paper is to put forward how the basics of chaos theory using a Lorenz system can be applied to the field of cryptography. In this work, stream ciphers have been used to encrypt the data generated by a Lorenz system.(More)
In cryptography, encryption is the process of transforming information referred to as plaintext using an algorithm (called a cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key. The result of the process is information which is, referred to as ciphertext. Stream ciphers are used to encrypt(More)
