Ballot Text

Technical Summary

The IPsec series of protocols makes use of various cryptographic algorithms
in order to provide security services.  The Internet Key Exchange (IKE) protocol
is used to negotiate the IPsec Security Association (IPsec SA) parameters, such 
as which algorithms should be used.  To ensure interoperability between different 
implementations, it is necessary to specify a set of algorithm implementation 
requirements and usage guidance to ensure that there is at least one algorithm 
that all implementations support. 

Working Group Summary

   The draft has WG consensus, no concerns to note.
