        • Sat\u00e8l\u00b7lits com a extensors de rang per a xarxes extrem-a-extrem QKD:<\/strong> Xarxa de defensa ultrasegura que combina QKD terrestre i satel\u00b7lit\u00e0ria amb un “node volant” per a llarga dist\u00e0ncia. Implementa protocols h\u00edbrids (QKD\/PQC) i comunicacions multiusuari (QCKA) mitjan\u00e7ant t\u00fanels VPN. Tot el sistema es valida amb simuladors avan\u00e7ats (DSS-Sim, QKDNetSim) al QuantumLab per blindar infraestructures cr\u00edtiques contra amenaces qu\u00e0ntiques.<\/li>\n\n\n\n

Combina senyals de radiofreq\u00fc\u00e8ncia (RF) i \u00f2ptiques amb sistemes d’apuntament millorats (PAT) per a una connexi\u00f3 h\u00edbrida robusta. Utilitza criptografia posqu\u00e0ntica (PQC) espec\u00edficament per a l’autenticaci\u00f3 d’usuaris i dispositius. Tot el sistema es gestiona mitjan\u00e7ant un KMS (Key Management System) conforme a l’est\u00e0ndard ETSI-014. S’integren la seguretat f\u00edsica i l’algor\u00edsmica per garantir la integritat de les infraestructures espacials.<\/li>\n<\/ul>\n\n<\/div>\n <\/div>\n<\/div>\n\n\n
