1. Introduction 

   RFC 3278 describes how to use Elliptic Curve Cryptography (ECC) 
   public-key algorithms in the Cryptographic Message Syntax (CMS).  
   This document updates RFC 3278 to add support for the SHA2 family of 
   hash algorithms. 

   The following summarizes the changes: 

    - Paragraph 2.1.1 limited the digest algorithm to SHA-1. This 
      document expands the allowed algorithms to SHA-224, SHA-256, SHA-
      384, and SHA-512. 

    - Paragraph 3.1.1 used SHA1 in the KDF with ECDH std and cofactor 
      methods.  This document expands the options to the allowed 
      algorithms to SHA-224, SHA-256, SHA-384, and SHA-512.

Internet-Draft             RFC 3278 Update                   April 2008 
    

    - Paragraph 3.1.2 used SHA1 in the KDF with ECMQV. This document 
      expands the options to the allowed algorithms to SHA-224, SHA-
      256, SHA-384, and SHA-512. 

    - Paragraph 5 was update to include requirements for hash algorithms 
      and recommendations for matching curves and hash algorithms. It 
      also was expanded to indicate which ECDH and ECMQV variants are 
      required. 

    - Paragraph 7 was update to include S/MIME capabilities for ECDSA 
      with SHA-224, SHA-256, SHA-384, and SHA-512. It was also updated 
      to include S/MIME capabilities for ECDH and ECMQV using SHA2 
      algorithms as the KDF.  

    - Paragraph 8.1 listed the algorithm identifiers for SHA-1 and SHA-1 
      with ECDSA. This document adds algorithms for SHA-224, SHA-256, 
      SHA-384, and SHA-512 and SHA-224, SHA-256, SHA-384, and SHA-512 
      with ECDSA. This document also updates the list of algorithm 
      identifiers for ECDH std, ECDH cofactor, and ECMQV with SHA2 
      algorithms as the KDF. 

    - Paragraph 9 references need to be updated. 

    - Added ASN.1 module. 

    - Security considerations paragraph referring to definitions of SHA-
      224, SHA-256, SHA-384, and SHA-512 needs to be deleted. 

2. Updates to Paragraph 2.1.1 

   Old: 

      digestAlgorithm MUST contain the algorithm identifier sha-1 (see 
      Section 8.1) which identifies the SHA-1 hash algorithm. 

      signatureAlgorithm contains the algorithm identifier ecdsa-with-
      SHA1 (see Section 8.1) which identifies the ECDSA signature 
      algorithm. 

   New: 

      digestAlgorithm MUST contain the algorithm identifier of the hash 
      algorithm (see Section 8.1) which MUST be one of the following: 
      id-sha1 identifies the SHA-1 hash algorithm, id-sha224 identifies 
      the SHA-224 hash algorithm, id-sha256 identifies the SHA-256 hash 
      algorithm, id-sha384 identifies the SHA-384 algorithm, and id-
      sha512 identifies the SHA-512 algorithm.

Internet-Draft             RFC 3278 Update                   April 2008 
    

      signatureAlgorithm contains the signature algorithm identifier 
      (see Section 8.1): ecdsa-with-SHA1, ecdsa-with-SHA224, ecdsa-
      with-SHA256, ecdsa-with-SHA384, or ecdsa-with-SHA512. 

3. Updates to Paragraph 3.1.1 

   Old: 

     keyEncryptionAlgorithm MUST contain the dhSinglePass-stdDH-sha1kdf-
     scheme object identifier (see Section 8.1) if standard ECDH 
     primitive is used, or the dhSinglePass-cofactorDH-sha1kdf-scheme 
     object identifier (see Section 8.1) if the cofactor ECDH primitive 
     is used.  The parameters field contains KeyWrapAlgorithm.  The 
     KeyWrapAlgorithm is the algorithm identifier that indicates the 
     symmetric encryption algorithm used to encrypt the content-
     encryption key (CEK) with the key-encryption key (KEK). 

   New: 

     keyEncryptionAlgorithm MUST contain the key encryption algorithm 
     object identifier (see Section 8.1).  The parameters field contains 
     KeyWrapAlgorithm.  The KeyWrapAlgorithm is the algorithm identifier 
     that indicates the symmetric encryption algorithm used to encrypt 
     the content-encryption key (CEK) with the key-encryption key (KEK). 
     Algorithm requirements are found in paragraph 5. 

4. Updates to Paragraph 3.2.1 

   Old: 

     keyEncryptionAlgorithm MUST be the mqvSinglePass-sha1kdf-scheme 
     algorithm identifier (see Section 8.1), with the parameters field 
     KeyWrapAlgorithm. The KeyWrapAlgorithm indicates the symmetric 
     encryption algorithm used to encrypt the CEK with the KEK generated 
     using the 1-Pass ECMQV algorithm. 

   New: 

     keyEncryptionAlgorithm MUST be the key encryption algorithm 
     identifier (see Section 8.1), with the parameters field 
     KeyWrapAlgorithm. The KeyWrapAlgorithm indicates the symmetric 
     encryption algorithm used to encrypt the CEK with the KEK generated 
     using the 1-Pass ECMQV algorithm. Algorithm requirements are found 
     in paragraph 5.

5. Updates to Paragraph 5 

   Add the following to the end of the section: 

      Implementations of this specification MUST implement the SHA-256 
      hash algorithm. The SHA-1, SHA-224, SHA-384, SHA-512 hash 
      algorithms MAY be supported. 

      When ECDSA, ECDH, or ECMQV is used, it is RECOMMENDED that the P-
      256 curve be used with SHA-256, the P-384 curve be used with SHA-
      384, and the P-521 curve be used with SHA-512. 

      Implementations of this specification that support EnvelopedData 
      with ephemeral-static ECDH standard primitive MUST support the  
      dhSinglePass-stdDH-sha256kdf-scheme algorithm. They MUST also 
      support the id-aes128-wrap algorithm. 

      Implementations of this specification that support EnvelopedData 
      with ephemeral-static ECDH cofactor primitive MUST support the 
      dhSinglePass-cofactorDH-sha256kdf-scheme algorithm. They MUST 
      also support the id-aes128-wrap algorithm. 

      Implementations of this specification that support EnvelopedData 
      with ECMQV MUST support the mqvSinglePass-sha256kdf-scheme 
      algorithm. They MUST also support the id-aes128-wrap algorithm. 

      Implementations of this specification that support 
      AuthenticatedData with ECMQV MUSt support the  
      mqvSinglePass-sha256kdf-scheme algorithm. They MUST also support 
      the id-aes128-wrap algorithm. 

6. Updates to Paragraph 7

      signature algorithm is the SEQUENCE with the capabilityID field 
      containing the object identifier ecdsa-with-SHA1 with NULL 
      parameters.  The DER encoding is:
