The Military University of Technology presented the first Polish quantum connection, achieved using Polish devices and domestic technology, guaranteeing full security of information transmission. 

The pioneering connection between the Military University of Technology and the Ministry of Digitization using Polish quantum key distribution (QKD) circuits demonstrated the possibilities for increasing digital independence and the potential of domestic equipment for secure communications. The developed quantum communications technology guarantees full immunity to interception of transmitted information. 

The tool – Modular Quantum Optical Cryptography System – was developed as part of the OptoKrypt project funded by NCBR and carried out by a consortium consisting of the WAT Institute of Optoelectronics (leader), TELDAT Sp. z o.o. and NASK National Research Institute. The project was initiated and overseen by the Cyber Defense Forces, setting new standards and directions in the development of data transmission security. The solution is a key component of the European satellite communications initiative. 

QKD technology guarantees full protection against eavesdropping and interception of transmitted information. In the face of growing cyber threats, including from quantum computers, the ability to secure strategic communications is critical to national security. 

The connection between the Military University of Technology and the Ministry of Digitization utilized two QKD sets and a trusted node at NASK. It was secured with the IPSEC protocol with AES-256 encryption, ensuring resistance to data interception. 

The OptoKrypt project is an innovative approach to protecting strategic communications in the face of growing cyber threats – it guarantees full protection of transmitted information from interception, even by quantum computers.
