We have an
Idea to merge
the technology
of smart cards
and TPM modules
to solve the
problem of
facilitating Old
non-TCPA PC
systems with
this
technology using
an external
device instead
of replacing
main parts of
the system
(e.g.,
motherboard,
adapters, etc.).
0 Introduction
to TPM (may bw
skipped or fast
tracked)
1 The problem :
1-1 facilitating
Old non-TCPA PC
systems with
this technology
1-2 Enabling
(Where it needs)
a non-TCPA PC to
be client of an
TCPA-enabled VPN
1-3 Motivationg
TCG aims on
migration of
more and more
PCs (an hence
users) to TCPA
2 The solution :
External TPM
2-1 Features:
2-1-1 Smart-Card
based
2-1-2 USB or old
RS-232
connnection is
used
2-1-3
2-2 Why
Smart-Card based
solution
(comparison)
2-2-1 structure
2-2-2 Features
and Facilities
2-3 May TPM be
External?

4 Development
(All-in-One
security
solution)
4-1 Java Card
Multi-Application
Solution
4-1-1 1st
Default
Application:
External TPM
4-1-2 Joining
with Windows
CSP: USB token
4-1-3 Software
protection
Dongle against
irregular copy
4-1-4 E-Commerce
applications:
EMV-aproved
applets
First we prove
that a TPM
module may be
external and
this has not any
contradiction
with the TCPA
standard
principles.
Second, this
device makes the
system private
enough for
predefined
user(s)
as well as an
embedded,
hard-bound TPM
chip.
And at last,
using the
technology
trends of smart
cards
(multi-application
cards, Global
platform, …) we
provide new
exciting Ideas
with this
external
TPM tokens.
Commercially
speaking, really
we have not any
market-ready
device, and we
are
in Research
phase of
producing such a
device. We are
concerned to use
the
opportunity of
attending to
this conference
and presenting
this Idea and
brain-storming
with other
research groups
and partners.
