1.  Introduction

   Mandatory algorithms may change over time due to an evolving threat
   landscape.  As a result these are grouped into profiles that a device
   should use.

   the mandatory-to implement algorithms for SUIT are described in this
   draft in order to provide flexibility in the definition of algorithm
   profiles.

   An authentication algorithm is REQUIRED for ALL SUIT manifests.
   Encryption algorithms MAY be provided.

2.  Algorithms

   The algorithms that form a part of the profiles defined in this
   document are grouped into:

   *  Digest Algorithms

   *  Authentication Algorithms

   *  Key Exchange Algorithms

   *  Encryption Algorithms
