National bodi

42、es that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other i

43、nternational organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules gi

44、ven in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval

45、 by at least 75 % of the national 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 and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 18045 was prepared by Joint

46、Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 27, IT Security techniques. The identical text of ISO/IEC 18045 is published by the Common Criteria Project Sponsoring Organisations as Common Methodology for Information Technology Security Evaluation. The common XML source

47、for both publications can be found at http:/i.es/xml. This second edition cancels and replaces the first edition (ISO/IEC 18045:2005), which has been technically revised.
