1  Introduction

   The Cryptographic Message Syntax (CMS) is cryptographic algorithm
   independent.  This specification defines a profile for the use of
   Elliptic Curve Cryptography (ECC) public key algorithms in the CMS.
   The ECC algorithms are incorporated into the following CMS content
   types:

      -  'SignedData' to support ECC-based digital signature methods
         (ECDSA) to sign content
