Quantum cryptography is a knowledge that guarantees ultimate safety. Associated to present cryptography that might be overcome by the expansion of an ultra-high-speed computer, quantum cryptography safeguards secure message since it is founded on the important bodily laws. It is an emergent technology in which two parties may concurrently produce shared, secret cryptographic key substantial usi...

Visual cryptography is one kind of image encrypting. It is different from traditional cryptography, because it does not need complex computation to decrypt. In current technology, most of visual cryptography are embedded a secret using two shares is limited. This paper proposes a new approach of (3, 3)visual secret sharing scheme to embed more information and have more secure than traditional v...

The Java Cryptography Architecture, JCA in short, was created to allow JCA-compliant cryptography providers to be plugged into a JCA-aware application at run time. This configurable feature makes JCA widely used and assures its success. However, the public key cryptographic service interfaces defined by JCA are based on the conventional public key cryptography, which is a single-sender-singlere...

Quantum Cryptography is based upon the use of quantum effects and extends those effects for conventional cryptographic methods. The two major advantages of quantum cryptography over conventional cryptography are true random secret key generation and eavesdropping detection. Quantum cryptography has been developed which promises more secure communication than any existing technique and cannot be...

Cryptography is the science of writing in secret message and is an ancient art. In data and telecommunications, cryptography is necessary when communicating over any untrusted medium, which includes just about any network, particularly over the Internet. Over the last two decades an interesting field of the cryptography has raised from non classical atomic theory, Quantum Physics. This field is...

It is believed that the quantum cryptography based on quantum key distribution achieves unconditional security. However, the additional authentication mechanism applied to the quantum cryptography needs to be studied since it is difficult for the quantum cryptography alone to prevent manin-the-middle attacks. Thus, we propose two authentication mechanisms combined with modern cryptography that ...

Lattice cryptography is one of the hottest and fastest moving areas in mathematical cryptography today. Interest in lattice cryptography is due to several concurring factors. On the theoretical side, lattice cryptography is supported by strong worst-case/average-case security guarantees. On the practical side, lattice cryptography has been shown to be very versatile, leading to an unprecedented...

The primary goal of this class is to bring students to a level where they understand enough about cryptography to use it intelligently, while gaining some insight into how cryptographic operations work. However, it is not a cryptography class in the sense of learning the science of cryptography, and the Stallings book is similarly focused and does not discuss the science of cryptography. The pu...
