Diffie Hellman key Exchange algorithm with an example is explained in the above video.Diffie Hellman key Exchange algorithm is used to transfer keys or exchange keys between two partners.Diffie Hellman key Exchange algorithm is a public key exchange type of algorithm.Diffie Hellman key Exchange algorithm is widely used in situations where eavesdropping is present. i.e. the medium across which information is sent can be hacked easily and information can be obtained.Diffie-Hellman key exchange algorithm does not have an effect of eavesdropping and hence it becomes a secure mode of transmission of key.Thus key can be exchanged using the Diffie-Hellman key exchange algorithm.In this video I have tried to explain the algorithm.After explaining the Diffie Hellman key Exchange algorithm I have also put an example for better understanding.What makes Diffie Hellman key Exchange algorithm so powerful? What are the conditions which are to be checked before key exchange? These things have also been explained in the video.The example explained in the video will easily remove doubts about the Diffie Hellman key exchange algorithm.I hope you liked the video.

This animation by the Centre for Quantum Technologies at the National University of Singapore illustrates the process of quantum key distribution using entangled photons. The goal is for two people in different places to end up with identical keys by measuring these photons. We want these people - usually given the names Alice and Bob - to have a random sequence of 1s and 0s that they can use to scramble (and then unscramble) a message. The presence of entanglement between the photons means that any snooping will be revealed. Note: this animation has no sound.

What is QUANTUM CRYPTOGRAPHY? What does QUANTUM CRYPTOGRAPHY mean? QUANTUM CRYPTOGRAPHY meaning - QUANTUM CRYPTOGRAPHY definition - QUANTUM CRYPTOGRAPHY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. The best known example of quantum cryptography is quantum key distribution which offers an information-theoretically secure solution to the key exchange problem. Currently used popular public-key encryption and signature schemes (e.g., RSA and ElGamal) can be broken by quantum adversaries. The advantage of quantum cryptography lies in the fact that it allows the completion of various cryptographic tasks that are proven or conjectured to be impossible using only classical (i.e. non-quantum) communication (see below for examples). For example, it is impossible to copy data encoded in a quantum state and the very act of reading data encoded in a quantum state changes the state. This is used to detect eavesdropping in quantum key distribution. History: Quantum cryptography uses Heisenberg's uncertainty principle formulated in 1927, and the No-cloning theorem first articulated by Wootters and Zurek and Dieks in 1982. Werner Heisenberg discovered one of the fundamental principles of quantum mechanics: "At the instant at which the position of the electron is known, its momentum therefore can be known only up to magnitudes which correspond to that discontinuous change; thus, the more precisely the position is determined, the less precisely the momentum is known, and conversely” (Heisenberg, 1927: 174–5). This simply means that observation of quanta changes its behavior. By measuring the velocity of quanta we would affect it, and thereby change its position; if we want to find a quant's position, we are forced to change its velocity. Therefore, we cannot measure a quantum system's characteristics without changing it (Clark, n.d.) and we cannot record all characteristics of a quantum system before those characteristics are measured. The No-cloning theorem demonstrates that it is impossible to create a copy of an arbitrary unknown quantum state. This makes unobserved eavesdropping impossible because it will be quickly detected, thus greatly improving assurance that the communicated data remains private. Quantum cryptography was proposed first by Stephen Wiesner, then at Columbia University in New York, who, in the early 1970s, introduced the concept of quantum conjugate coding. His seminal paper titled "Conjugate Coding" was rejected by IEEE Information Theory Society, but was eventually published in 1983 in SIGACT News (15:1 pp. 78–88, 1983). In this paper he showed how to store or transmit two messages by encoding them in two "conjugate observables", such as linear and circular polarization of light, so that either, but not both, of which may be received and decoded. He illustrated his idea with a design of unforgeable bank notes. In 1984, building upon this work, Charles H. Bennett, of the IBM's Thomas J. Watson Research Center, and Gilles Brassard, of the Université de Montréal, proposed a method for secure communication based on Wiesner's "conjugate observables", which is now called BB84. In 1991 Artur Ekert developed a different approach to quantum key distribution based on peculiar quantum correlations known as quantum entanglement. Random rotations of the polarization by both parties (usually called Alice and Bob) have been proposed in Kak's three-stage quantum cryptography protocol. In principle, this method can be used for continuous, unbreakable encryption of data if single photons are used. The basic polarization rotation scheme has been implemented. The BB84 method is at the basis of quantum key distribution methods. Companies that manufacture quantum cryptography systems include MagiQ Technologies, Inc. (Boston, Massachusetts, United States), ID Quantique (Geneva, Switzerland), QuintessenceLabs (Canberra, Australia) and SeQureNet (Paris, France).
