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.
