Quantum Security for University Networks Protection

In this era of electronic communication, where computers and other manual devices are sending and receiving messages via wireless networks, security and privacy has always been a fundamental concern. Wireless network is an open medium with air as a transmission media involving radio frequencies which have been easily decode-able since World War II. But, behind every wireless network there is a core network which is normally wired. World has become a global village due to this effective approach of wireless communication. It is an alarming issue now days to secure our core network providing wireless services for home, universities, government and military. Many security protocols have been implemented to secure core networks but there are a great number of security risks associated with the current protocols and encryption methods. Secure information transactions takes place within the limited realms of key encryption and exchange techniques. For secure information transaction, a secret key must be known to both the sender and the receiver hiding it from outside world. This study highlighted the implementation of secure communication of key and successfully addressed the security threats in core network designed for King Faisal University (KFU) accomplished by quantum cryptography. The study also suggested to investigate alternate Quantum Key Distribution (QKD) architectures exploring application of emerging QKD in wireless sensor network and its modeling in a real network.
