As an essential part of QKD system, the design of post-processing system has a huge influence on its key generation rate. For the challenges of real-time and high-speed processing requirements, we propose a pipeline optimization model for QKD post-processing system. With the variable granularity...
Quantum key distribution (QKD) protocols based on high-dimensional quantum states have shown the route to increase the key rate generation while benefiting of enhanced error tolerance, thus overcoming the limitations of two-dimensional QKD protocols. Nonetheless, the reliable transmission through fiber li...
A high speed QKD system requires an expeditious realization of authentication. We develop an authentication computation core based on field programmable gate array (FPGA) which can reach the throughput of 4.8 Gbps and 1.6 Gbps. A detailed protocol to guarantee the functionality of the authentication ...
We develop an authentication computation core based on Field Programmable Gate Array(FPGA) which can reach the throughput of 4.8Gbps and 1.6Gbps is used for practical QKD system. A detailed protocol to guarantee the functionality of the authentication computation core is also proposed....
The FPGAs can easily process 10–100 billions of Gigabytes of IoT traffic per day, corresponding to 100 s of billions of transmitted IoT packets/second, to detect and eliminate all malicious communications by external cyber-attackers, in hardware and in real-time. Hardware-based security is ...
