9、on. National bodies 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
10、interest. Other international 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
11、with the rules given 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
12、requires approval 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.

25、uent object identifiers Each of the signature schemes uses a hash-function, a sequence containing a hash algorithm identifier and any associated parameters. Therefore, the signature scheme object identifier may be followed by one of the dedicated hash-function algorithm identifiers specified in ISO/
26、IEC 10118-3 and any associated parameters. Using the ASN.1 XML value notation, a value of type SignatureWithMessageRecovery using normal signature processing mechanism 1 defined in this Standard and the SHA-1 hash-function defined in ISO/IEC 10118-3 would be represented as: 1.0.9796.2.0.1.0 1.3.14.3
27、.2.26 A value of type SignatureWithMessageRecovery using the combined object identifier for normal signature processing mechanism 1 and the SHA-1 hash-function has the simpler form: 1.0.9796.2.2.1.0 INCITS/ISO/IEC 9796-2-2002/Amd.1-2008INCITS/ISO/IEC 9796-2-2002/Amd.1-2008 ICS 35.040 Price based on 4 pages ITIC 2008 All rights reserved
