IS 15899 : 2023/ISO 16609 : 2022 Financial Services - Requirements for Message Authentication Using Symmetric Techniques
NATIONAL FOREWORD
This Indian Standard (Second Revision) which is identical to ISO 16609 : 2022 'Financial services - Requirements for message authentication using symmetric techniques' 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.
This standard was first published in 2012 as an identical adoption of ISO 16609 : 2004 'Banking - Requirements for message authentication using symmetric techniques' under dual numbering system and further revised in 2017. This second revision has been undertaken to align the Indian Standard with the latest version of ISO 16609 that is, ISO 16609 : 2022 'Financial services - Requirements for message authentication using symmetric techniques'.
This revision cancels and replaces the previous edition, of which it constitutes a minor revision. The main changes to the previous edition are as follows:
a) Updated to include newer hash functions specified in updated versions of the ISO/IEC 9797 series.
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.
