Data Security Using Cryptography and Steganography Techniques

Although cryptography and steganography could be used to provide data security, each of them has a problem. Cryptography problem is that, the cipher text looks meaningless, so the attacker will interrupt the transmission or make more careful checks on the data from the sender to the receiver. Steganography problem is that once the presence of hidden information is revealed or even suspected, th...

Recent Advances in Information Security

Recent years have witnessed rapid developments of the information communication technology and the next-generation Internet. We have seen the potential and value for new technologies from a variety of digital networks to various interconnected digital devices, which make it possible to realize the ubiquitous network and society. But, in such environment , copyright infringement behaviors, such ...

Quantum Cryptography and Security of Information Systems

We show concept of BB84 quantum key distribution (QKD) protocol and analyze its use as an information system. The difference between classical and quantum cryptography is presented in a way of understanding the main advantage of quantum information processing over classical information processing. At the end of the article, we present today and future use of quantum cryptography and possible im...
