Hello dear = WG,

the last call = for ERS closed a few days ago and I received from the cross = review from the SMIME mailing-lists and members of LTANS some valuable input = for final corrections.

The = corrections = I made were small and should not impact existing = implementations.

According to = the review I = made the corrections and send the = new version = draft-ietf-ltans-ers-10.txt again to = the secretary and it will be published in the = next few hours. I believe = the document is now ready for submission to the IESG.

Thanks to all the = reviewers of ERS, and = especially thanks to Denis and Peter.

- = Tobias


The following = modifications were made:

1. Corrected a = reference on page 9 = about = encryptionInfo “... For discussion of syntax please refer to = chapter 5.1” = changed = to = “…chapter 6.1”

2. corrected a small = typo = encryptionInfo was = written in some structures with encryptionInfos which prevented correct implementation.

(thanks to Denis)

3. in Appendix A: inserted the = missing = “OBJECT = IDENTIFIER” to the definition of now

id-EvidenceRecord-Internal OBJECT IDENTIFIER ::=3D {id-em = 1}

and

id-EvidenceRecord-External OBJECT IDENTIFIER ::=3D {id-em = 2}

(thanks to Denis and Carl for = finding this error)

3. added an optional field in = ArchiveTimeStamp to give an LTA the possibility to = store additional information at the level of the individual = ArchiveTimeStamp, e.g. a = Policy used at the = various times of the renewal processes.

(inspired by Denis and Carl)

   ArchiveTimeStamp ::=3D SEQUENCE {

     digestAlgorithm [0] AlgorithmIdentifier = OPTIONAL,

     attributes      = [1] Attributes OPTIONAL,

     reducedHashtree [2] SEQUENCE OF = PartialHashtree OPTIONAL,

     = timeStamp       = ContentInfo}

   PartialHashtree ::=3D SEQUENCE OF OCTET = STRING

   Attributes ::=3D SET SIZE (1..MAX) OF = Attribute


The Attribute structure is imported from RFC3852 (for current ASN.1 from = InformationFramework).

FYI:

Attribute ::=3D SEQUENCE {

        attrType OBJECT = IDENTIFIER,

        attrValues SET OF = AttributeValue }

      AttributeValue ::=3D = ANY


4. Support of both ASN.1 = syntax (1988 and = current):

This item was quite tricky and = Peter and I worked the last few days on it. Thanks to the great help from Peter, we finally managed to provide = two fully compatible ASN.1 structures: one = supporting 88 syntax and one the current ASN.1.

 

5. As requested during the cross review from = SMIME, added two paragraphs to 1.2 General Overview and = Requirements

To explain the different scenarios = where timestamp renewal and hash tree renewal in more detail as = recommended by Denis:

“  Note: Information about the weakening of the security = properties of

   public key and hash algorithms as well as the risk of = compromise of

   private keys of Time Stamping Units has to be closely = watched by the

   Long Term Archive provider or the owner of the data = objects himself.

   This information should be gathered by "out of = bands" means and is

   out of scope of this document.)  ERS = distinguishes two ways for

   renewal of an Archive Timestamp: Timestamp Renewal and = Hash-Tree

   Renewal.”

“  The timestamp renewal is necessary if the private key of = a

   Timestamping Unit has been compromised, an asymmetric = algorithm or a

   hash algorithm used for the generation of the = timestamps is no longer

   secure for the given key size.  If the hash = algorithm used to build

   the hash trees in the Archive Timestamp looses its = security

   properties the Hash-Tree Renewal is = required.”


6. As requested during the cross = review from SMIME, added to appendix A a short explanation about why it to = store ERS within the CMS structure:

“  One advantage of storing the Evidence Record within the CMS = structure

   is that all data can be transferred in one conclusive = file and is

   directly connected.  The documents, the = signatures and their Evidence

   Records can be bundled and managed together.  The = description in the

   appendix contains the normative specification of how = to integrate ERS

   in CMS structures.”


7. as the Attribute structure is = also the exact match for the CryptoInfo structure used for the OPTIONAL = CryptoInfos, I also = used it here instead of writing it up:

So new CryptoInfos is

CryptoInfos ::=3D SEQUENCE SIZE = (1..MAX) OF Attribute

Writing it out would have = been:

CryptoInfos ::=3D SEQUENCE SIZE = (1..MAX) OF = CryptoInfo

CryptoInfos ::=3D = SEQUENCE {

        cryptoInfoType OBJECT = IDENTIFIER,

        cryptoInfoValues SET = OF cryptoInfoValue }

      cryptoInfoValue ::=3D ANY


8. corrected the listing of a = normative reference: reference to RFC3280 was missing

9. = very few corrections, = were text was not fully conform with RFC2119
