WebDistribución de claves cuánticas. La distribución de claves cuánticas (en inglés Quantum Key Distribution, QKD) es un método de comunicación segura que implementa un protocolo criptográfico que involucra componentes de mecánica cuántica. Permita que dos partes creen una clave secreta al azar compartida conocida solo por ellos, que ...

WebIn cryptography, an original human readable message, referred to as plaintext, is changed by means of an algorithm, or series of mathematical operations, into something that to an … A security protocol (cryptographic protocol or encryption protocol) is an abstract or concrete protocol that performs a security-related function and applies cryptographic methods, often as sequences of cryptographic primitives. A protocol describes how the algorithms should be used and includes details about data structures and representations, at which point it can be used to implement multiple, interoperable versions of a program. power bi shape map county
