18、8 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a
19、subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission
20、 (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical com
21、mittees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not
22、 be held responsible for identifying any or all such patent rights. ISO 17090-3 was prepared by Technical Committee ISO/TC 215, Health informatics. This first edition cancels and replaces the Technical Specification (ISO/TS 17090-3:2002), which has been revised and brought to the status of Internati
23、onal Standard. ISO 17090 consists of the following parts, under the general title Health informatics Public key infrastructure: Part 1: Overview of digital certificate services Part 2: Certificate profile Part 3: Policy management of certification authority SANS 17090-3:2009This s tandard may only b

New models of
25、healthcare delivery are emphasizing the need for patient information to be shared among a growing number of specialist healthcare providers and across traditional organizational boundaries. Healthcare information concerning individual citizens is commonly interchanged by means of electronic mail, re
26、mote database access, electronic data interchange and other applications. The Internet provides a highly cost-effective and accessible means of interchanging information, but it is also an insecure vehicle that demands additional measures be taken to maintain the privacy and confidentiality of infor
27、mation. Threats to the security of health information through unauthorized access (either inadvertent or deliberate) are increasing. It is essential to have available to the healthcare system reliable information security services that minimize the risk of unauthorized access. How does the healthcar
28、e industry provide appropriate protection for the data conveyed across the Internet in a practical, cost-effective way? Public key infrastructure (PKI) and digital certificate technology seek to address this challenge. The proper deployment of digital certificates requires a blend of technology, pol
29、icy and administrative processes that enable the exchange of sensitive data in an unsecured environment by the use of “public key cryptography” to protect information in transit and “certificates” to confirm the identity of a person or entity. In healthcare environments, this technology uses authent
30、ication, encipherment and digital signatures to facilitate confidential access to, and movement of, individual health records to meet both clinical and administrative needs. The services offered by the deployment of digital certificates (including encipherment, information integrity and digital sign
31、atures) are able to address many of these security issues. This is especially the case if digital certificates are used in conjunction with an accredited information security standard. Many individual organizations around the world have started to use digital certificates for this purpose. Interoper
32、ability of digital certificate technology and supporting policies, procedures and practices is of fundamental importance if information is to be exchanged between organizations and between jurisdictions in support of healthcare applications (for example between a hospital and a community physician w
33、orking with the same patient). Achieving interoperability between different digital certificate implementations requires the establishment of a framework of trust, under which parties responsible for protecting an individuals information rights may rely on the policies and practices and, by extensio
34、n, the validity of digital certificates issued by other established authorities. Many countries are deploying digital certificates to support secure communications within their national boundaries. Inconsistencies will arise in policies and procedures between the certification authorities (CAs) and
35、the registration authorities (RAs) of different countries if standards development activity is restricted to within national boundaries. Digital certificate technology is still evolving in certain aspects that are not specific to healthcare. Important standardization efforts and, in some cases, supp
36、orting legislation are ongoing. On the other hand, healthcare providers in many countries are already using or planning to use digital certificates. ISO 17090 seeks to address the need for guidance of these rapid international developments. ISO 17090 describes the common technical, operational and p
37、olicy requirements that need to be addressed to enable digital certificates to be used in protecting the exchange of healthcare information within a single domain, between domains and across jurisdictional boundaries. Its purpose is to create a platform for global interoperability. It specifically s
38、upports digital certificate-enabled communication across borders, but could also provide guidance for the national or regional deployment of digital certificates in healthcare.

39、of the SABS .ISO 17090-3:2008(E) vi ISO 2008 All rights reservedis increasingly used as the vehicle of choice to support the movement of healthcare data between healthcare organizations and is the only realistic choice for cross-border communication in this sector. ISO 17090 should be approached as
40、a whole, with the three parts all making a contribution to defining how digital certificates can be used to provide security services in the health industry, including authentication, confidentiality, data integrity and the technical capacity to support the quality of digital signature. ISO 17090-1
41、defines the basic concepts underlying the use of digital certificates in healthcare and provides a scheme of interoperability requirements to establish digital certificate-enabled secure communication of health information. ISO 17090-2 provides healthcare-specific profiles of digital certificates ba
42、sed on the international standard X.509 and the profile of this, specified in IETF/RFC 3280 for different types of certificates. This part of ISO 17909 deals with management issues involved in implementing and using digital certificates in healthcare. It defines a structure and minimum requirements
43、for certificate policies (CPs) and a structure for associated certification practice statements. This part of ISO 17090 is based on the recommendations of the informational IETF/RFC 3647, and identifies the principles needed in a healthcare security policy for cross border communication. It also def
44、ines the minimum levels of security required, concentrating on the aspects unique to healthcare.
