SAML 2.0 Profile for ECR Policy Assertions

Information icon.svg This profile applies to scenarios where the eCR Context Manager requests an Access Policy Assertion from the eCR Policy Provider and thus implements a policy push authorization model. There is no specification in the case that the Authorization Decision Provider requests policies from the eCR Policy Provider.
Assertion Element Opt Usage Convention
@Version R MUST be “2.0”
@ID R URN encoded unique identifier (UUID) of the assertion
@IssueInstant R time instant of issuance in UTC
Issuer R address URI that identifies the endpoint of the issuing service
Subject R This element defines the subject confirmation method of the user in order to use the Policy Assertion as a supporting token. Moreover, it defines the subject name identifier that accords with the user identity from an Identity Assertion.
NameID R Identifier of the HP given in the Identity Asstertion encoded as an X.509 subject name, an e-Mail address or as a string value (unspecified format). Only identifiers must be used that can be long-term tracked back to an individual person.
@Format R MUST be urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified

or urn:oasis:names:tc:SAML:1.1:nameid-format:X509SubjectName
or urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress
For providing an OID as a subject identifier the unspecified format must be used. The OID must be provided as a string encoded in ISO format.

SubjectConfirmation R
@Method R This element MUST hold a URI reference that identifies a protocol to be used to authenticate the subject.[SAML2.0core] The value of this element MUST be set to

urn:oasis:names:tc:SAML:2.0:cm:holder-of-key

SubjectConfirmationData R
ds:KeyInfo R The XML Signature [XMLSignature] element MUST embed a cryptographic key that is only held by the user. This can be the user’s public key (ds:KeyValue/ds:RSAKeyValue), the complete user’s X.509 certificate (ds:X509Data/ds:X509Certificate), or an encrypted symmetric key (xenc:EncryptedKey [XMLEncryption]). This symmetric key MUST be encrypted by using the public key of the consumer service’s certificate [eFA PKI 1.2].
Conditions R
@NotBefore R time instant from which the assertion is useable. This condition MUST be assessed by the assertion consumer to proof the validity of the assertion.
@NotOnOrAfter R Time instant at which the assertion expires. This condition MUST be assessed by the assertion consumer to proof the validity of the assertion. The maximum validity timespan for a Policy Assertion MUST NOT be more than 4 hours.
XACMLPolicyStatement R
Policy or PolicySet R Policy or PolicySet that expresses the authorization (see section below for details).
ds:Signature R Enveloped XML signature of the issuer of the Policy Assertion (see section below for details).
