Some of the claims seem a little broad, like this first one:
1. A method for establishing a pseudonym system by having a certificate
authority accepting a user as a new participant in said pseudonym system,
the method comprising the steps of: receiving a first public key

Carl Ellison suggested an alternate way that TCPA could work to allow
for revoking virtualized TPMs without the privacy problems associated
with the present systems, and the technical problems of the elaborate
cryptographic methods.
Consider first the simplest possible method, which is just to
With Brands digital credentials (or Chaums credentials) another
approach is to make the endorsement key pair and certificate the
anonymous credential. That way you can use the endorsement key and
certificate directly rather than having to obtain (blinded) identity
certificates from a privacy CA

Here are some more thoughts on how cryptography could be used to
enhance user privacy in a system like TCPA. Even if the TCPA group
is not receptive to these proposals, it would be useful to have an
understanding of the security issues. And the same issues arise in
many other kinds of systems
