Summary:
|
If the delay associated with the generation and distribution of cryptographic keys provided by a QKDN were required to match stringently the level of delay in modern cryptographic schemes, it would be practically impossible to meet such requirements over the QKDN exceeding a certain length. However, if the QKDN is deployed within a range where secure communications are acceptable to the end users, the corresponding QoS can be regarded as satisfactory.
Therefore, this Recommendation first aims to introduce the user satisfaction for cryptography service in user network , and subsequently identify the relationship between the user satisfaction and QKDN QoS, then derive calculation principle of the quantitative QoS objectives for QKDN that are capable of meeting those user satisfaction thresholds.
This recommendation describes the quantitative objectives aspects for delay-related QoS parameters of QKDN. It aims to provide support for the implementation of QKD network to assure QoS requirements.
