Information security — Security requirements, test and evaluation methods for quantum key distribution — Part 2: Evaluation and testing methods

This document specifies test and evaluation methods for the security evaluation of quantum key distribution (QKD). It also describes evaluation activities that constitute the test and evaluation methods for the security functional requirements on the implementation of QKD protocols, the quantum optical components and conventional network components in QKD modules. Moreover, supplementary evaluation activities for security assurance requirements are provided to support the security evaluation of QKD with appropriate assurance levels.
