Key concepts: Proof of Origin: Verifies the sender's identity, ensuring that the message or data genuinely comes from the claimed source. Digital signatures and certificates are commonly used for this purpose. Proof of Integrity: Ensures that the data has not been altered or tampered with. This is typically achieved through hashes or cryptographic checksums. RESUMEN El no repudio es una medida de seguridad que impide que alguien niegue sus acciones o responsabilidades relacionadas con una comunicaciรณn o transacciรณn digital. Conceptos clave: Prueba de origen: verifica la identidad del remitente, lo que garantiza que el mensaje o los datos provienen genuinamente de la fuente declarada. Las firmas y los certificados digitales se utilizan comรบnmente para este propรณsito. Prueba de integridad: garantiza que los datos no hayan sido alterados ni manipulados. Esto se logra generalmente a travรฉs de hashes o sumas de comprobaciรณn criptogrรกficas.
