              Data Structure for the Security Suitability
                   of Cryptographic Algorithms (DSSC)

Abstract

   Since cryptographic algorithms can become weak over the years, it is
   necessary to evaluate their security suitability.  When signing or
   verifying data, or when encrypting or decrypting data, these
   evaluations must be considered.  This document specifies a data
   structure that enables an automated analysis of the security
   suitability of a given cryptographic algorithm at a given point of
   time, which may be in the past, the present, or the future.

Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.
