CSA Preface

This is the first edition of CAN/CSA-ISO/TS 17090-1, Health informatics - Public key infrasturcture - Part 1: Framework and overview, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Technical Specification 17090-1 (first edition, 2002-10-15).

At the time of publication, ISO/TS 17090-1:2002 is available from ISO in English only.

Scope

This part of ISO/TS 17090 defines the basic concepts of a healthcare public key infrastructure (PKI) and provides a scheme of interoperability requirements to establish a PKI enabled secure communication of health information.

It also identifies the major stakeholders who are communicating in health, as well as the main security services required for health communication where PKI may be required. This part of ISO/TS 17090 gives a brief introduction to public key cryptography and the basic components of a healthcare PKI.

It further introduces different types of certificates, public key identity certificates and associated attribute certificates, for relying parties, self-signed certification authority (CA) certificates, and CA hierarchies and bridging structures.
