The Key Distribution QKD Quantum Key Distribution is a method of securely sharing cryptographic keys between two parties typically referred to as Alice and Bob using quantum mechanics principles. 2. Understanding Quantum Mechanics Basics Quantum Superposition Quantum superposition is a fundamental principle where a quantum system exists in multiple measured. Quantum Entanglement Quantum entanglement is a phenomenon where particles become correlated in such a way that the state of one particle instantly influences the state of another regardless of the distance between them. 3. The Need for Secure Communication With the exponential growth of digital
communication theres an increasing demand for secure transmission of sensitive data such as financial transactions government communications and personal information. 4. How Quantum Key Distribution Works Quantum Key Distribution operates on the principle that any attempt to measure a quantum system disturbs its state thus alerting the communicating Philippines Email List parties to the presence of an eavesdropper. Generating Quantum Keys Quantum keys are generated by encoding information on individual quantum particles such as photons in various quantum states. Quantum Encryption Once the quantum keys are generated they are used to encrypt the data ensuring that only the intended recipient decipher the message.
Key Distribution Protocols Various protocols such as BB84 and E91 are used to exchange quantum keys securely between the communicating parties. 5. Advantages of Quantum Key Distribution Unbreakable Encryption QKD offers encryption that is theoretically unbreakable even against adversaries with unlimited computational power. InformationTheoretic Security Unlike classical encryption methods which rely on computational assumptions QKD provides security based on the laws of physics offering informationtheoretic security. Resistance to Quantum Computing Attacks QKD is resistant to attacks from quantum computers which have the potential to break traditional encryption algorithms. 6. Challenges and Limitations of QKD Practical Implem.
