From 8579cf80c3602f963566d31eaf04f59f68d3bf11 Mon Sep 17 00:00:00 2001 From: Thomas Knall Date: Thu, 29 Jan 2015 10:56:18 +0100 Subject: Add STORK process (MOAID-58). - Add STORKAuthentication.process.xml - Add PepsConnectorTask using code from PEPSConnectorServlet. - Split code from PEPSConnectorWithLocalSigningServlet into PepsConnectorHandleResponseWithoutSignatureTask and PepsConnectorHandleLocalSignResponseTask. - Replace SpringExpressionEvaluator within applicationContext.xml with SpringWebExpressionEvaluator (allowing expressions using request parameter(s)). - Make servlet mappings /PEPSConnectorWithLocalSigning and /PEPSConnector point to the process engine signaling servlet. - Add many FIXMEs marking problematic code. - Move code to start stork authentication from StartAuthenticationBuilder to CreateStorkAuthRequestFormTask. - Mark PEPSConnectorServlet and PEPSConnectorWithLocalSigningServlet deprecated. - Remove @author tknall from classes assembled using existing (bogus) code. --- .../moa/id/auth/AuthenticationServer.java | 13 +- .../auth/builder/StartAuthenticationBuilder.java | 28 +- .../moa/id/auth/servlet/PEPSConnectorServlet.java | 1 + .../PEPSConnectorWithLocalSigningServlet.java | 1 + .../moa/id/auth/tasks/AbstractAuthServletTask.java | 3 - .../id/auth/tasks/CertificateReadRequestTask.java | 5 +- .../id/auth/tasks/CreateIdentityLinkFormTask.java | 1 - .../moa/id/auth/tasks/GetForeignIDTask.java | 1 - .../moa/id/auth/tasks/GetMISSessionIDTask.java | 1 - .../auth/tasks/PrepareAuthBlockSignatureTask.java | 1 - .../auth/tasks/VerifyAuthenticationBlockTask.java | 1 - .../moa/id/auth/tasks/VerifyCertificateTask.java | 1 - .../moa/id/auth/tasks/VerifyIdentityLinkTask.java | 9 +- .../AbstractPepsConnectorWithLocalSigningTask.java | 258 ++++++++++ .../stork/CreateStorkAuthRequestFormTask.java | 114 +++++ .../PepsConnectorHandleLocalSignResponseTask.java | 218 ++++++++ ...onnectorHandleResponseWithoutSignatureTask.java | 441 ++++++++++++++++ .../moa/id/auth/tasks/stork/PepsConnectorTask.java | 567 +++++++++++++++++++++ 18 files changed, 1619 insertions(+), 45 deletions(-) create mode 100644 id/server/idserverlib/src/main/java/at/gv/egovernment/moa/id/auth/tasks/stork/AbstractPepsConnectorWithLocalSigningTask.java create mode 100644 id/server/idserverlib/src/main/java/at/gv/egovernment/moa/id/auth/tasks/stork/CreateStorkAuthRequestFormTask.java create mode 100644 id/server/idserverlib/src/main/java/at/gv/egovernment/moa/id/auth/tasks/stork/PepsConnectorHandleLocalSignResponseTask.java create mode 100644 id/server/idserverlib/src/main/java/at/gv/egovernment/moa/id/auth/tasks/stork/PepsConnectorHandleResponseWithoutSignatureTask.java create mode 100644 id/server/idserverlib/src/main/java/at/gv/egovernment/moa/id/auth/tasks/stork/PepsConnectorTask.java (limited to 'id/server/idserverlib/src/main/java') diff --git a/id/server/idserverlib/src/main/java/at/gv/egovernment/moa/id/auth/AuthenticationServer.java b/id/server/idserverlib/src/main/java/at/gv/egovernment/moa/id/auth/AuthenticationServer.java index c33e5c735..cf50a1bf5 100644 --- a/id/server/idserverlib/src/main/java/at/gv/egovernment/moa/id/auth/AuthenticationServer.java +++ b/id/server/idserverlib/src/main/java/at/gv/egovernment/moa/id/auth/AuthenticationServer.java @@ -1402,8 +1402,8 @@ public class AuthenticationServer implements MOAIDAuthConstants { * Retrieves a session from the session store. * * @param id session ID - * @return AuthenticationSession stored with given session ID, - * null if session ID unknown + * @return AuthenticationSession stored with given session ID (never {@code null}). + * @throws AuthenticationException in case the session id does not reflect a valic, active session. */ public static AuthenticationSession getSession(String id) throws AuthenticationException { @@ -1707,10 +1707,6 @@ public class AuthenticationServer implements MOAIDAuthConstants { // String acsURL = new DataURLBuilder().buildDataURL(issuerValue, // PEPSConnectorServlet.PEPSCONNECTOR_SERVLET_URL_PATTERN, moasession.getSessionID());

      + * In detail: + *

        + *
      • Decodes and validates the SAML response from the C-PEPS.
        • + *
      • Change moa session id.
        • + *
      • Extracts the subject's gender from request parameter {@code gender} if not available from the saml response.
        • + *
      • Extracts the {@code signedDoc} attribute from the response, get signed doc payload using stork attribute query request.
        • + *
      • Request SZR gateway for verification of the citizen's signature and for creating of an identity link.
        • + *
      • In case of mandate mode: If the S-PEPS did not provide any gender information, the szr gateway will not be able to issue an identity link. Therefore a form is presented asking for the subject's gender. The form submits the user back to the {@code /PepsConnector} servlet (this task).
        • + *
      • The moa session is updated with authentication information.
        • + *
      • Change moa session id.
        • + *
      • Redirects back to {@code /dispatcher} in order to finalize the authentication.
        • + *
      + * Expects: + *
        + *
      • HttpServletRequest parameter {@code SAMLResponse}
        • + *
      • Either HttpServletRequest parameter {@code RelayState} or {@code inResponseTo} attribute from the SAML response (both depicting the moa session id)
        • + *
      • HttpServletRequest parameter {@code gender} in case the request comes from the gender selection form
        • + *
      • {@code signedDoc} attribute within the SAML response.
        • + *
      + * Result: + *
        + *
      • Updated moa id session (identity link, stork attributes...)
        • + *
      • {@link ExecutionContext} contains boolean flag {@code identityLinkAvailable} indicating if an identitylink has been successfully creates or not.
        • + *
      • Redirect to {@code /dispatcher}.
        • + *
      + * Possible branches: + *
        + *
      • In case the szr gateway throws exception due to missing gender information: + *
          + *
        • Returns a form for gender selection with action url back to this servlet/task.
