Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives or www.iec.ch/members_experts/refdocs ).

ISO and IEC draw attention to the possibility that the implementation of this document may involve the use of (a) patent(s).

Introduction

The ISO/IEC 23837 series specifies security requirements, test and evaluation methods for quantum key distribution (QKD) modules under the framework of the ISO/IEC 15408 series. This document specifies an evaluation method and relevant evaluation activities for the security evaluation of QKD modules in a relatively general way. The evaluation activities that are necessary for the security evaluation of QKD modules include supplementary evaluation activities for the QKD-related security functional requirements (SFRs) specified in ISO/IEC 23837-1 and the supplementary evaluation activities for security assurance requirements (SARs) with security assurance levels ranging from evaluation assurance level (EAL) 1 to EAL 5+.

Specifically, the evaluation activities for the testing and evaluation of implementations of QKD protocols, quantum optical components in QKD transmitter modules, and QKD receiver modules are described in detail. For SFRs specific to conventional network components, this document does not specify concrete evaluation activities but mainly refers to existing methods for network devices. In addition, supplementary activities for security assurance requirements are specified, and refinements to the generic vulnerability analysis methodology in ISO/IEC 18045 are presented, including guidance on the calculation of attack potentials.

This document is expected to provide a specification to help QKD manufacturers improve the design and implementation security of QKD modules, and to guide evaluators in the testing and security evaluation of QKD modules, thus reducing the risk of failure of security in operation.

1 Scope

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.
