CSA ISO/IEC 23837-1:25

CSA Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. For brevity, this Standard will be referred to as "CSA ISO/IEC 23837-1" throughout. The International Standard was reviewed by the CSA Technical Committee on Cybersecurity under the jurisdiction of the CSA Strategic Steering Committee on Information and Communications Technology Systems and deemed acceptable for use in Canada. This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This document specifies a general framework for the security evaluation of quantum key distribution (QKD) according to the ISO/IEC 15408 series. Specifically, it specifies a baseline set of common security functional requirements (SFRs) for QKD modules, including SFRs on the conventional network components and the quantum optical components, and the entire implementation of QKD protocols. To facilitate the analysis of SFRs, security problems that QKD modules can face in their operational environment are analysed based on a structural analysis of the security functionality of QKD modules and the classification of QKD protocols. The SFRs on conventional network components of QKD modules are mainly characterized under the framework of the ISO/IEC 15408 series and also refer to the methodology of ISO/IEC 19790 and relevant standards on testing of cryptographic modules and network devices.
