TAILIEUCHUNG - Recommendation for Key Management – Part 1: General (Revision 3)

The report is part of the stock-taking needed in the run-up to Rio+20, but is also necessary in order to recalibrate the sustainable development compass to allow Earth’s seven billion inhabitants, which will rise to over nine billion by 2050, to prosper and fulfill their full potential. Rio+20 is likely to set a process in motion to deliver a range of new goals for after 2015 aimed at bringing rich and poor nations into more cooperative efforts towards a sustainable 21st century. This report, rich in analysis and recommendations, can assist in defining how those new transformational goals can be forged – and, more importantly, be met –. | NIST Special Publication 800-57 Recommendation for Key Management - Part 1 General Revision 3 Elaine Barker William Barker William Burr William Polk and Miles Smid C O M P U T E R S E C U R I T Y Computer Security Division Information Technology Laboratory National Institute of Standards and Technology Gaithersburg MD 20899-8930 July 2012 .
