A strategy for any DAA Issuer and an additional verification by a Host
Abstract: A successful strategy was identified
for any Verifier colluding with any Issuer
to distinguish honest Provers issuing DAA signatures.
An additional verification equation was introduced
for a Prover to detect 'tagged' credentials
that may be issued while Join protocol.
This verification can be done by the Host
and do not affect TPM in any way.
