Why QKD and Q- network Encryptor network Encryptor Encryptor Secure communica2on Tunnel Encryptor Key distribu2on Secure communica2on = Secure encryp2on + Secure key distribu2on
Why QKD and Q- network Cryptography at present For de/encrypt For key exchange Symmetric Cryptography AES IDEA Strong RC6 RSA RSA Asymmetric Cryptography ECC ECC Not Strong D- H n RSA512 is broken in 1999 n RSA768 is broken in 2009 n RSA1024 is broken in. n All Asymmetric Cryptography at present can be broken by Shor s quantum algorithm n No asymmetric Cryptography can be uncondi2onal secure

2 Product landscape and design QLAN QMAN QWAN Applica2on Centralized Control Sta2on n Convergence node and trusted relay in MAN n Time Division Mul2plexing to reduce total- cost
2 Product landscape and design QLAN QMAN QWAN Applica2on Why trusted relay? There was a gap between the period of prac:cal Quantum computer and Quantum repeater, meanwhile the trusted relay is the best choice A huge quantum computer like this may be fatal to asymmetric cryptography But a quantum repeater of similar size can not be set up in the most today telecom carrier room
