6. Cyber Ridge Emerges from Stealth with Photonic Encryption

• Overview:
  Israeli startup Cyber Ridge unveiled a quantum-secure 'Photonic Encryption' tech with $26M in funding.
• Details:
  • Transforms transmitted data into encrypted optical signals.
  • Employs constantly changing photonic keys, aiming to foil future 'harvest now, decrypt later' quantum attacks.
  • Already adopted in European, Australian, Singaporean, and Israeli defense/intelligence sectors.
• Quote:
  “The system requires a constantly changing photonic key to access data, aiming to block harvest now, decrypt later attacks.”
