===UltraConnect Antenna===
When IBM enabled their builtin notebook antennas to support the 802.11a and 802.11g as well as the 802.11b wireless networking standard, they rebranded them as UltraConnect antenna.

The UltraConnect Antennas are built into the top corners of the ThinkPads display and are connected to a [[Ethernet Controllers|network controller]] in the ThinkPads [[MiniPCI slot]].

Embedded Security Subsystem

2006-07-17T14:23:35Z

LVT: /* IBM Embedded Security Subsystem 2.0 */

{| width="100%"
|style="vertical-align:top;padding-right:20px;width:10px;" | [[Image:ESS.jpg|IBM Embedded Security Subsystem]] __NOTOC__
|style="vertical-align:top" |
<div style="margin: 0; margin-right:10px; border: 1px solid #dfdfdf; padding: 0em 1em 1em 1em; background-color:#F8F8FF; align:right;">
=== The Embedded Security Subsystem ===
The Embedded Security Subsystem is nothing but a chip installed on the ThinkPads mainboard that can take care of certain security related tasks conforming to the TCPA standard. It was first introduced among the T23 models and is now under the name Embedded Security Subsystem 2.0 an integral part of most of the modern ThinkPads. The functions of the chip are bound to three main groups:
* public key functions
* trusted boot functions
* initialization and management functions

The purpose of the whole thing is to keep the user's sensitive data out of range from software based attacks (like viruses, internet attacks etc.). One way the chip offers to achieve this is by providing storage for keys along with the neccessary functions to handle them within itself, so that a i.e. a private key never has to leave the chip (can't be seen by any piece of software). Besides this there are more complex topics covered by the functionality of the chip. If you want to find out more about it you can find good documents on the [http://www.research.ibm.com/gsal/tcpa/ IBM Research TCPA resources page].</div>
|}

==WARNING==
There's a bug in the latest release of the security chip software. You end up facing a security chip login, and you press Ctrl-alt-delete, and it just sits there. DO NOT Download the latest patch (Dated 13/06/2006 v 7.00.0017.00) <BR>
Actaully they appear to have removed that patch.<BR>
Ring IBM support (in Australia 131426, 1, 2) and they'll talk you through doing a system restore.<BR>

==Trusted or Treacherous?==

TC - Trusted Computing - will be the biggest change of the information landscape since decades. Besides positive features like a more secure hardware storage for cryptographic keys, an analysis of the proposed TCG-standards shows some problematic properties. <br />
As ThinkPads of recent generations following the ThinkPad {{T23}} ([[Embedded Security Subsystem#Models featuring this Technology|see the complete list of models]]) are equipped with this disputed TCG-/TCPA-Technology, it can be interesting, which promises of the TCG are fulfilled inside your ThinkPad and which parts of the TCG-specifications still seem to be a privacy issue for every user of digital devices like a MP3-player or a ThinkPad - so please read [[TCPA/TCG - Trusted or Treacherous|this article]] for more details.

==Linux Support==
Two linux drivers are available, a [[tpm|classical one]] and a [[tpmdd|newer one]].
Coverage of functionality of the first is unknown so far, the second is part of a bigger project aiming to provide a usable security framework.

David Stafford (one of the developers of the tpm code at IBM) on March 10, 2005 sent me the most recent version of the tpm-kml code. With his permission, I quote his email:

"I am attaching our latest driver and library.
This version is in the process of kernel mailing list review, and
will hopefully be accepted into the official kernel. It works
much better across various 2.6 kernels. Note that this builds
three modules tpm, tpm_atmel, and tpm_nsc. You modprobe the
tpm_atmel (for all current shipping atmel based systems), or
tpm_nsc (for the coming national based systems).

Also note that there is a conflict with the snd-intel8x0
kernel module (they each try to grab the LPC bus). You can
either: load the tpm modules first (such as in initrd or
rc.sysinit, before sound), or recompile the snd-intel8x0, turning
off the MIDI and JOYSTICK support. The latest 2.6.11 version
of snd-intel8x0 also reportedly fixes things."

Compiling this library was easy. Compiling the driver on my 2.6.8-686 (debian testing) laptop failed. But the library works with the driver I compiled from the tpm-2.0 package IBM made available on its pages (see the links below).

Gijs

The T43 requires a patch posted to the LKML by Kylene Jo Hall: [http://marc.theaimsgroup.com/?l=linux-kernel&m=111884603309146&w=2 LKML posting]. An updated patch for linux 2.6.12 is available [http://shamrock.dyndns.org/~ln/linux/tpm_2.6.12.diff here].

The atmel driver comes with 2.6.12.

now suported in 2.6.15.1(and mabe others kernels under this number) in:

==Versions & Features==
=== Embedded Security Chip ===
IBM introduced it's TCPA/TCG features with some of the [[:Category:T23|T23]] models. The earlier of them didn't yet have the Embedded Security Subsystem, but a kind of pre 1.0 version called the Embedded Security Chip. This chip had the following capabilities:
*Data communications authentication and encryption
*Storage of encrypted passwords

=== Embedded Security Subsystem (1.0) ===
The original Embedded Security Subsystem (in IBM documents there is no use of the additive version-number 1.0) claims to be compliant with TCG specs, but apparently did not fully implement any specific TCG spec.

The Embedded Security Subsystem has the following features:
*hardware key storage
*multi-factor authentication
*local file encryption
*enhances VPN security

=== Embedded Security Subsystem 2.0 ===
The Embedded Security Subsystem 2.0 conforms to the TCG TPM 1.1b specification, with a TPM manufactured by either Atmel or National Semiconductor.

The Embedded Security Subsystem 2.0 has the following features:
*hardware key storage
*multi-factor authentication
*local file encryption
*enhances VPN security
*TCG compliant
