NATIONAL FOREWORD
This Indian Standard which is identical to ISO 11568 : 2023 'Financial services - Key management (retail)' issued by International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendations of Banking and Financial Services Sectional Committee, and approval of the Service Sector Division Council.
The following series of ISO standards are revised and merged as ISO 11568 : 2023:
a) ISO 11568 (Part 1) : 2005
b) ISO 11568 (Part 2) : 2012
c) ISO 11568 (Part 4) : 2007
Considering the revision and merger of above standards, the following Indian standards are also revised and merged as IS 15256 : 2023/ISO 11568 : 2023:
a) IS 15256 (Part 1) : 2011/ISO 11568-1 : 2005
b) IS 15256 (Part 2) : 2016/ISO 11568-2 : 2012
c) IS 15256 (Part 4) : 2013/ISO 11568-4 : 2007
This standard supersedes and replaces the former ISO 11568 series. The following are significant modifications that have been incorporated to the standard:
a) all parts of the series combined into a single document;
b) fixed key no longer included in the permissible methods of transaction key management;
c) required key replacement policy added;
d) cleartext key injection removed; and
e) AES DUKPT introduced as a key management method.
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
