Signature parameter to SEASCustomExitInterface class

Hi Team,

To perform actual authentication, the client sends a signature generated using the private key.

It is a SSH signature verification.

To perform signature verification, customer backend generic solution need the following data in the authentication request:

  • Username

  • Service/tenant name

  • Public key

  • Public key algorithm

  • Signature

When the server receives this message, it MUST check whether the supplied key is acceptable for authentication, and if so, it MUST check whether the signature is correct.


For more details on this kindly go-through PMR#TS010510969.


Regards,

Ahmed

How will this idea be used?

As part of the customer implementation we are using IBM Sterling external Authentication Server 6.0.3 and we are using Generic Authentication method.
Here I would like to know how to pass "Signature parameter" to "SEASCustomExitInterface" class.

This class has below list parameters:

String REQKEY_CLIENTID = "clientId";
String REQKEY_CORRELATOR = "correlator";
String REQKEY_IPADDRESS = "ipAddress";
String REQKEY_APPINPUTS = "appInputs";
String REQKEY_APPOUTPUTS = "appOutputs";
String REQKEY_EXITOUTPUTS = "exitOutputs";
String REQKEY_CERTS = "certs";
String REQKEY_ISSERVER = "isServer";
String REQKEY_USERID = "userId";
String REQKEY_PASSWORD = "password";
String REQKEY_NEWPASSWORD = "newPassword";
String REQKEY_SECURITY_CODE = "securityCode";
String REQKEY_MAGIC_NUMBER = "magicnumber";
String REQKEY_DSTSVC = "destinationService";
String REQKEY_SSHPUBLICKEY = "sshpublickey";
String REQKEY_SSHPUBLICKEY_B64 = "sshpublickey_b64";
String RSPKEY_DAYS_UNTIL_PWD_EXPIRES = "daysUntilPwdExpires";
String RSPKEY_PWD_POLICY = "pwdPolicy";

Because of this RFE, we can get to know, which parameter should use or how to pass signature from SSP to SEAS (SEASCustomExitInterface).

    Thank you for taking the time to provide your ideas to IBM. We appreciate your willingness to share details about your experience and your recommendations. After our initial review we understand that currently the check on Sender possesing Private key with respect to Public key is achived via Deamon (Maveric toolkit) We would need further discussion on this with your technical team. Please look forward to the invite on the same. Thanks

    Appreciate your patience.


    Thanks,

    Product Management

    Hi IBM team,

    As per Mastercard's Security standards end to end authentication request which is being processed and validated from SEAS external custom exist interface must contain signature value of incoming user request so that downstream Authentication Service of Mastercard would be able to perform proper authentication of request by validating signature value and generate auth token accordingly.


    Kindly expediate this SSP SEAS feature development at your end and provide us a project delivery timelines for our Mastercard's implementation planning purpose.


    Thanks,

    Nitin Rane
