[xmlsec] problem verifying a signature

The xmlsec output says that the Reference's digest was successfully
verified but after that the RSA signature verification for SignedInfo
element failed. There are only two options: the problem is in the key or
the problem is in the signed data. The 1023 keys size looks strange
and the first thing I would suggest you to try is to delete <KeyValue/>
child of <KeyInfo/> and see if this would make any difference.

To verify that data are correct, you can use "--store-signature" option
in xmlsec. This would print out the data that xmlsec signs. IF you can
get same output from Ubisignature then you can compare it.
