The work of preparing International Standards is normally carried out thro
15、ugh ISO technical committees. Each member body interested in a 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 collabor
16、ates closely with the International Electrotechnical Commission (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 Standa
17、rds. Draft International Standards adopted by the technical committees 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 t
18、his document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15782-1 was prepared by Technical Committee ISO/TC 68, Financial services, Subcommittee SC 2, Security management and general banking operations. This second edition
19、 cancels and replaces the first edition (ISO 15782-1:2003), which has been technically revised. ISO 15782 consists of the following parts, under the general title Certificate management for financial services: Part 1: Public key certificates Part 2: Certificate extensions BS ISO 15782-1:2009ISO 1578
20、2-1:2009(E) ISO 2009 All rights reserved vIntroduction This part of ISO 15782 adopts ISO/IEC 9594-8 for the financial services industry and defines certificate management procedures and data elements. Detailed requirements for the financial industry for the individual extensions are given in ISO 157
21、82-2. While the techniques specified in this part of ISO 15782 are designed to maintain the integrity of financial messages and support the service of non-repudiation, this part of ISO 15782 does not guarantee that a particular implementation is secure. It is the responsibility of the financial inst
22、itution to put an overall process in place with the necessary controls to ensure that the process is securely implemented, with these controls including the application of appropriate audit tests in order to validate compliance. The binding association between the identity of the owner of a public k
23、ey and that key is documented in order to prove the ownership of the corresponding private key. This binding is called a public key certificate. Public key certificates are generated by a trusted entity known as a Certification Authority (CA). The proper implementation of this part of ISO 15782 is i
24、ntended to provide assurances of the binding of the identity of an entity to the key used by that entity to sign documents, including wire transfers and contracts. This part of ISO 15782 defines a certificate management framework for authentication, including the authentication of keys for encryptio
25、n. The techniques specified by this part of ISO 15782 can be used when initiating a business relationship between legal entities (entities). BS ISO 15782-1:2009BS ISO 15782-1:2009INTERNATIONAL STANDARD ISO 15782-1:2009(E) ISO 2009 All rights reserved 1Certificate management for financial services Pa
26、rt 1: Public key certificates 1 Scope This part of ISO 15782 defines a certificate management system for financial industry use for legal and natural persons that includes credentials and certificate contents, Certification Authority systems, including certificates for digital signatures and for enc
27、ryption key management, certificate generation, distribution, validation and renewal, authentication structure and certification paths, and revocation and recovery procedures. This part of ISO 15782 also recommends some useful operational procedures (e.g. distribution mechanisms, acceptance criteria
28、 for submitted credentials). Implementation of this part of ISO 15782 will also be based on business risks and legal requirements. This part of ISO 15782 does not include the protocol messages used between the participants in the certificate management process, requirements for notary and time stamp
29、ing, Certificate Policy and Certification Practices requirements, or Attribute Certificates. While this part of ISO 15782 provides for the generation of certificates that could include a public key used for encryption key management, it does not address the generation or transport of keys used for e
30、ncryption. Implementers wishing to comply with ISO/IEC 9594-8 can utilize the certificate structures defined by that International Standard. Those wishing to implement compatible certificate and certificate revocation structures but without the overhead associated with the X.500 series can utilize t
31、he ASN.1 structures defined in ISO 15782-2. ISO 15782-2 can also be referred to for a financial services profile of certificate and CRL extensions. ISO 21188 provides additional information for implementers on Certificate Policies, Certification Practice Statements, and PKI controls. ISO 21188 sets
32、out a framework of requirements to manage a PKI through Certificate Policies and Certification Practice Statements and to enable the use of public key certificates in the financial services industry. It also defines control objectives and supporting procedures to manage risks. NOTE The use of a bold
33、 sans serif font, such as CertReqData or CRLEntry, denotes the use of abstract syntax notation (ASN.1), as defined in ISO/IEC 8824-1 to ISO/IEC 8824-4 and ISO/IEC 8825-1 and ISO/IEC 8825-2. Where it makes sense to do so, the ASN.1 term is used in place of normal text. Refer to ISO 15782-2 for relate
34、d ASN.1 modules.

NOTE 1 The Certificate Policy should be used by the user o
44、f the certificate to decide whether or not to accept the binding between the subject (of the certificate) and the public key. Some of the components in the Certificate Policy framework are given concrete values and represented by a registered object identifier in the X.509, Version 3 certificate. Th
45、e object owner also registers a textual description of the policy and makes it available to the Relying Parties. NOTE 2 The Certificate Policy object identifier can be included in the following extensions in the X.509, Version 3 certificates: Certificate Policies, policy mappings, and policy constra
46、ints. The object identifier(s) may appear in none, some, or all of these fields. These object identifiers may be the same (referring to the same Certificate Policy) or may be different (referring to different Certificate Policies). 3.9 certificate policy framework comprehensive set of security- and
