13、: sheffieldun sheffieldun, na, Sun Nov 26 14:25:08 GMT+00:00 2006, Uncontrolled Copy, (c) BSI iv Foreword 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 car
14、ried out through 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.
15、 ISO collaborates 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 Interna
16、tional Standards. 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
17、elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 20828 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. BS ISO 20828:2006 Licensed C

Cryptography provides
19、 excellent means for this kind of protection. Depending on the protection requirements, different schemes may be used. In some situations it is sufficient to lock a data link involving a specific device, and to unlock it only if a second device has sent the correct key in response to an arbitrary se
20、ed. The corresponding security access service is specified in various International Standards and is widely used today. ISO 15764 defines an extended security scheme. It does not just restrict the access to data, but protects the data when transmitted over the data link. Protection is provided again
21、st masquerade, replay, eavesdropping, manipulation and repudiation. Before starting the secured data transmission, the data link must be established as a secured link. ISO 15764 provides two methods for this: a) Both devices participating in the data transmission have a pre-established secret crypto
22、graphic key. This key is used to establish the secured link and excludes all third parties not having access to it from participating in the secured link. This method is based on symmetric keys and is applicable to devices with a limited processing power and memory. b) The secured link may be establ
23、ished between arbitrary devices, if these devices have a private key and a security certificate for the corresponding public key. This method involves asymmetric cryptography requiring a higher amount of processing power and memory at the devices. Public keys are cryptographic keys that are publicly
24、 available and are linked to a private key, which is kept secret by the device owning it. There are two ways of using a public/private key pair: a) The device owning the private key may add an electronic signature to data it sends out. This signature is specific for the data sent out and may only be
