III. QKD System System overview SKT QKD system is based on ATCA(Advanced Telecommunication and Computing Architecture) and easily extend the capacity of encrypted data by adding encryptor slots. Additionally, SKT is developing more flexible platform like QKD sever only, etc. 40 Gbps encryptor (4 ports 10G) (Ethernet, SONET) Quantum key server (Optical Part) Quantum key server (Signal Processing Part) Control & Switch
