Iran Launches QKD Network to End Invisible Eavesdropping

Javad Salehi, a faculty member of Sharif University of Technology and the project executor, described the project a starting point for the expansion of quantum technology in Iran, and said, “The designed network is equipped with advanced quantum receiver and transmitter equipment and optical switches. In this project, the O band in optical fiber is used for quantum communications, which allows for secure coexistence with classical communications. The network is designed in such a way that it uses the existing fiber optic infrastructure in Tehran and eliminates the need to create a new physical platform.”

“Implementation of this network will put Iran among the few countries with an operational quantum key distribution infrastructure and can significantly improve communication security in sensitive areas like e-government, banking systems, and healthcare services," he added.

"This project also paves the way for the formation of specialized knowledge-based companies in the field of quantum communications," Salehi said.

Invisible eavesdropping refers to the act of secretly listening to private conversations or communications without the knowledge or consent of the individuals involved. This can be achieved through various methods, including using covert listening devices like "bugs" or wiretaps, or through more sophisticated techniques like laser eavesdropping or exploiting vulnerabilities in smart devices. 

Also QKD is a secure communication method that utilizes quantum mechanics to generate and distribute cryptographic keys. These keys are then used to encrypt and decrypt messages, ensuring secure communication between two parties. 

QKD is considered a promising technology for achieving long-term security in an era where quantum computers could potentially break current encryption methods.
