A signed assertion is one which contains a signature that the identity provider creates by using an algorithm chosen by the identity provider administrator. All SAML authentication requests supported by Informatica use a signed assertion.

The certificate is a standard X.509 certificate used to sign the assertions within the SAML tokens that the identity provider issues to Informatica web applications. You can generate a self-signed Secure Sockets Layer (SSL) certificate, or you can get a certificate from a certificate authority, and then import it into the identity provider.

To enable the signed assertion, export the assertion signing certificate from the identity provider.
