Quantum Mechanics
Privacy amplification is a technique used in quantum cryptography to enhance the level of security and privacy of a shared key between two parties. This process involves the distillation of a raw key, which may be partially compromised due to potential eavesdropping, into a more secure key that minimizes the amount of information that an eavesdropper could gain. By using methods such as error correction and privacy amplification protocols, the parties can significantly reduce the possibility of an unauthorized party accessing the key, ensuring a higher level of confidentiality in their communications.
congrats on reading the definition of privacy amplification. now let's actually learn it.
