Summary:
|
Quantum key distribution network (QKDN) is a cryptographic infrastructure to provide secure symmetric keys to cryptographic applications in user networks. Constructing a large scale QKDN which covers wide area, it may consist of multiple QKDNs and they are interworking each other.
The functional requirements and architecture of single QKDN are specified based on the functional requirements of QKDN in [ITU-T Y.3801], functional architecture and operational procedures of QKDN in [ITU-T Y.3802]. This recommendation is to specify a framework for interworking QKDNs. Security considerations are mentioned when it is directly related to the security of keys.
This Recommendation will consider the following aspects for interworking QKDNs.
1) Interworking between QKDNs supported by different QKDN providers.
NOTE - QKDN provider is specified in [draft ITU-T Y.QKDN_BM].
2) Interworking between QKDNs with different technologies.
Different technologies can be used in QKDNs such as:
- Key relay encryption methods (i.e. OTP, AES etc.)
- Key relay schemes (i.e. case 1 and case 2 which are specified in [ITU-T Y.3800])
- Key relay alternatives (i.e. XORs uniformly processed at destination node etc. which are specified in [ITU-T Y.3803])
- Configurations of QKDN controller (i.e. centralized QKDN or distributed QKDN which are specified in [ITU-T Y.3802]
- Protocols in the key management layer, the QKDN control layer and the QKDN management layer.
NOTE - Details of protocols is outside the scope of this Recommendation.
