Syntax for the extnesion value QCStatements

xipki commented 2 months ago

The ASN.1 syntax:

RFC 3739

QCStatements ::= SEQUENCE OF QCStatement

QCStatement ::= SEQUENCE {
   statementId        OBJECT IDENTIFIER,
   statementInfo      ANY DEFINED BY statementId OPTIONAL}

SemanticsInformation  ::= SEQUENCE {
   semanticsIndentifier        OBJECT IDENTIFIER OPTIONAL,
   nameRegistrationAuthorities NameRegistrationAuthorities OPTIONAL
   } -- At least one field shall be present

NameRegistrationAuthorities ::= SEQUENCE SIZE (1..MAX) OF GeneralName

id-qcs-pkixQCSyntax-v1   OBJECT IDENTIFIER ::= { id-qcs 1 } -- 1.3.6.1.5.5.7.11.1
id-qcs-pkixQCSyntax-v2   OBJECT IDENTIFIER ::= { id-qcs 2 } -- 1.3.6.1.5.5.7.11.2

ETSI EN 319 412-5

-- EU qualified certificate declaration
esi4-qcStatement-1 QC-STATEMENT ::= { IDENTIFIED BY id-etsi-qcs-QcCompliance }

id-etsi-qcs-QcCompliance OBJECT IDENTIFIER ::= { id-etsi-qcs 1 }

-- Declaration of limit value
esi4-qcStatement-2 QC-STATEMENT ::= { SYNTAX QcEuLimitValue IDENTIFIED
 BY id-etsi-qcs-QcLimitValue }

QcEuLimitValue ::= MonetaryValue

MonetaryValue::= SEQUENCE {
  currency Iso4217CurrencyCode,
  amount INTEGER,
  exponent INTEGER}
  -- value = amount * 10^exponent

Iso4217CurrencyCode ::= CHOICE {
 alphabetic PrintableString (SIZE (3)), -- Recommended
 numeric INTEGER (1..999) }
 -- Alphabetic or numeric currency code as defined in ISO 4217
 -- It is recommended that the Alphabetic form is used

-- Retention period declaration
esi4-qcStatement-3 QC-STATEMENT ::= { SYNTAX QcEuRetentionPeriod IDENTIFIED
  BY id-etsi-qcs-QcRetentionPeriod }

QcEuRetentionPeriod ::= INTEGER

QcEuPDS ::= PdsLocations

PdsLocations ::= SEQUENCE SIZE (1..MAX) OF PdsLocation
PdsLocation::= SEQUENCE {
  url IA5String,
 language PrintableString (SIZE(2))} --ISO 639-1 language code

-- Certificate type
esi4-qcStatement-6 QC-STATEMENT ::= { SYNTAX QcType IDENTIFIED
  BY id-etsi-qcs-QcType }

QcType::= SEQUENCE OF OBJECT IDENTIFIER (id-etsi-qct-esign | id-etsi-qct-eseal |
  id-etsi-qct-web, ...)

-- country or set of countries under the legislation of which the certificate is issued as a
-- qualified certificate
esi4-qcStatement-7 QC-STATEMENT ::= { SYNTAX QcCClegislation IDENTIFIED
  BY id-etsi-qcs-QcCClegislation } 

QcCClegislation ::= SEQUENCE OF CountryName
CountryName ::= PrintableString (SIZE (2)) (CONSTRAINED BY { -- ISO 3166 alpha-2 codes only -- })

-- object identifiers
id-etsi-qcs OBJECT IDENTIFIER ::= { itu-t(0) identified-organization(4) etsi(0)
  id-qc-profile(1862) 1 }
id-etsi-qcs-QcCompliance OBJECT IDENTIFIER ::= { id-etsi-qcs 1 }

id-etsi-qcs-QcLimitValue OBJECT IDENTIFIER ::= { id-etsi-qcs 2 }

id-etsi-qcs-QcRetentionPeriod OBJECT IDENTIFIER ::= { id-etsi-qcs 3 }

ETSI TS 119 495

etsi-psd2-qcStatement QC-STATEMENT ::= {SYNTAX PSD2QcType IDENTIFIED BY id-etsi-psd2-qcStatement }

id-etsi-psd2-qcStatement OBJECT IDENTIFIER ::=
  { itu-t(0) identified-organization(4) etsi(0) psd2(19495) qcstatement(2) }

PSD2QcType ::= SEQUENCE{
  rolesOfPSP RolesOfPSP,
  nCAName NCAName,
  nCAId NCAId }

NCAName ::= UTF8String (SIZE (1..256))

NCAId ::= UTF8String (SIZE (1..256))

RolesOfPSP ::= SEQUENCE OF RoleOfPSP

RoleOfPSP ::= SEQUENCE{
  roleOfPspOid RoleOfPspOid,
  roleOfPspName RoleOfPspName}

RoleOfPspOid ::= OBJECT IDENTIFIER

CBOR: below is my proposed suggestion:

We need a new "Figure X: C509 Statement Identifiers", and the following syntax:

QCStatements = [* QCStatement ]

QCStatement = (statementId: int, statementInfo : any) /
            (statementId: ~oid/pen, statementInfo : bstr/null) -- statementInfo may be not present.

-- For qcs-pkixQCSyntax-v1  and qcs-pkixQCSyntax-v2
SemanticsInformation = [semanticsIdentifier:~oid/pen/null, nameRegistrationAuthorities:GeneralNames/null]

-- For esi4-qcStatement-1
The statementInfo is `null`.

-- For  esi4-qcStatement-2
MonetaryValue = [currency: Iso4217CurrencyCode, amount: uint, exponent: uint]

Iso4217CurrencyCode = tstr / uint

-- For  esi4-qcStatement-3
The statementInfo is uint (or int if negative value is allowed).

-- For esi4-qcStatement-4
The statementInfo is `null`.

-- For  esi4-qcStatement-5
PdsLocations = [ + PdsLocation ]

PdsLocation = (url:tstr, language:tstr)

-- For  esi4-qcStatement-6
QcType = [ * ~oid/pen ]

-- For  esi4-qcStatement-7
QcCClegislation = [*tstr]

-- For etsi-psd2-qcStatement
RoleOfPSP = (~oid/pen, tstr)

RolesOfPSP = [* RoleOfPSP]

PSD2QcType = [RolesOfPSP, tstr, tstr]

This is one of the currently “number only” extensions where we need to get a use case to determine if it is relevant to c509
Martin will look into ETSI standards to check if this extension is relevant, but other input is also welcome!

highlunder commented 3 weeks ago

we agree to include this in the upcoming COSE presentation to ask for input
