#### PPT A Cryptography Tutorial PowerPoint presentation

Implementation Security of Quantum Cryptography 3 Atilla Hasekioglu Consultant and Senior Researcher, Tubitak Bilgem, Kocaeli, Turkey Atilla Hasekioglu works as a coordinator for quantum technology related projects. Quantum cryptography is so powerful because it's physically impossible for a hacker to steal a key encoded using quantum particles. This site contains design and analysis of various computer algorithms such as divide-and-conquer, dynamic, greedy, graph, computational geometry etc. The presentation will start after a short (15 second) video ad from one of our sponsors. We describe results from an apparatus and protocol that is designed to implement the quantum key distribution by which two users who share no secret information (without having any private or public keys known. Origin of Cryptography – tutorialspoint.com Posted on December 2, 2017 by admin Human being from ages had two inherent needs (a) to communicate and share …. Cryptography converts data into a format that is unreadable for an unauthorized user, allowing it to be transmitted without unauthorized entities decoding it back into a …. But what exactly is quantum cryptography? 2 HISTORY OF CRYPTOGRAPHY 4 2 History of Cryptography Cryptography (from Greek krypt os "hidden" and gr aphein "writing")[2] is the art of creating secure codes, whereas cryptanalysis deals with breaking these codes. Although it is an old science, its scope of applications remained mainly restricted to military and diplomatic purposes until the. Quantum cryptography is the best example that these "drawbacks" can be turned into useful applications. Cryptography is an essential information security tool. Thanks to the low number of dark counts at the detectors and to the use of an ultralow-loss fiber, combined with a modification of a loss. Elliptic curve cryptography, or ECC, builds upon the complexity of the elliptic curve discrete logarithm problem to provide strong security that is not dependent upon the factorization of prime numbers. In linear-optical quantum computation, on-demand and indistinguishable single photons are required to implement measurement-induced quantum logic gates [3,4]. And that's where quantum cryptography comes in.

A more common use today of ID Quantique’s quantum-safe techniques is to secure commu- nications between data centres – between head office computers and back-up facilities, for example. Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. Quantum cryptography describes the use of quantum mechanical effects (in particular quantum communication and quantum computation) to perform cryptographic tasks or to break cryptographic systems. The use of classical (i.e., non-quantum) cryptography to protect against quantum …. Cryptography in the era of quantum computers. An optical-fiber-based quantum cryptography scheme works over a record distance of 421 km and at much faster rates than previous long-distance demonstrations. It is split into two main branches: superposition which is also used in quantum computing, and quantum entanglement, or the concept that particles are produced whose states cannot be described. Cryptography protects our information as it travels over and is stored on the internet—whether making a purchase from …. Quantum key distribution, or QKD, is a subset of quantum cryptography that allows two parties to produce a shared random key, which they can then use to encrypt and decrypt private messages. Quantum entanglement is one of the most out-of-the-box areas of study in physics today, including research into cool sounding things such as quantum cryptography, quantum computing, and quantum …. A good collection of links regarding books, journals, computability, quantum computing, societies and organizations. Quantum cryptography hinges on a technique called quantum key distribution (QKD). Cryptography involves creating written or generated codes that allow information to be kept secret. In the history of cryptography, quantum cryptography is a new and important chapter. Two major areas of quantum cryptography Quantum key exchange exchanging bits securely via a quantum channel, with the help of a classical channel, which can be public but must be authentic Cryptography on quantum …. Reversing the process - taking the large number and breaking it down into its prime factors - is incredibly time.

#### A simple C implementation of Elliptic Curve Cryptography

In other words, unlike with factoring, based on currently understood mathematics there doesn't appear to be a shortcut that is narrowing the gap. The elliptic curve discrete logarithm is the hard problem underpinning elliptic curve cryptography. The strength of the Elliptic Curve Cryptography lies in the Elliptic Curve Discrete Log Problem (ECDLP). For example, with ECC I know that there are different algorithms for implementing the point multiplication (double-and-add, double-and-add-always, Mo
