Hey guys I got a question.

i'm beginning work on a personal project soon. The rundown:

A briefcase mod
Tiny
Ubuntu or something else that is easy to use/run in there
LCD screen IN THE CASE
keyboard inside as well

in essence EVERYTHING inside. even the power connectors will be inside so you do'nt see a thing at the case.

What i will be:

The thing will be a movable hotspot to create a wireless acces point. The idea is to use a via epia mobo i THINK to make it as small as possible and as low power as possible (no heat so fanless cooling preferably or VERY light fan cooling)

it will be a hotspot as said so a good Wireless card which will get boosted with a 1W amplifier.

The idea is to have NO antenna as wel so it'll most likely be a full metal briefcase (yhea the expensive kind of briefcase) which i'll hook up to the network card (solder or something) which you can put down and just let't go.

The thing needs to be able to handle about the normal amount of computers meaning... 100 connection to it should be NO PROBLEM!
The normal span of a wifi card is... 30 meters radius IIRC or 30 meters diameter could also be it, well this thing needs to cover 100 meters worth of field WITHOUT LOSS OF SIGNAL. this is important. after the 100 meters the signal can deteriorate all it wants.

So now i need help.

I know my hardware a bit (;) ) but i do not know the via epia series.

i'm looking for a mobo that has:
A good processor which is relativly fast and can handle ubuntu and a :banana::banana::banana::banana:loads of other programs running at once.
use normal DDR1
has a integrated GPU (also passive cooled please) which can handle a good resolution (1024 IS THE BARE MINIMUM) but the 3D performance may suck badly.
which has a good chipset so that data can be easely shipped. I intend to log all traffic going through the thing and also log the apps it is running.

Now the applications will be going from:
FTP/WEb server + CS:S dedicated server and some other random stuff for like a small lan party

to FTP+WEB+Logging+encrypting all the data that goes through it and save it in a encrypted form + secure connection to the thing so that people can remote it/fetch important data off it so no 3rd party's can get to it.

So as you can see quite a lot.
The FTP and web and logging will stress the RAM/HDD quite a bit and the encrypting of EVERYTHING on the rig will take a good toll on the CPU.

also whatever it does, EVERYTHING needs to be encrypted. so the entire HDD needs to be encrypted/decrypted on the fly. if it needs data it needs to fetch it in its encrypted form of the HDD and decrypt it to use it wich will stress the CPU even more.

So i bassicly need help and advice.

What via epia mobo will do for me? Any experiences? can you reccomend another small form factor mobo with CPU and GPU EMBEDDED so I don't want ot buy a mobo seperatly and a CPU seperatly. no it needs to have it all.

The WIFI card isn't a requirement that its onboard seeing as the on board one will most likly be crap and not able to handle 100 connections at once.

So can you guys help em out?

I particulary need info on the linux. i'm going for ubuntu thanks to its ease to use and very stable in my opinion but i don't know how to do the encryption. I'm thinking AES 256 bit encryption on the fly as I said.

The web etc will just be a apache run but as i said this system needs to be:
Stable
capable of handling the load
BE SECURE.

I can't afford intrusions/a leaky application. the software needs to be air and watertight as possible.

Thanks for any help/advice you can give me.

Cheers

i think you're going to run into a problem with the lack of cpu power from the embedded cpu series mobos. with that much encryption on the fly i don't think the 600-800mhz via cpus are going to cut it. i may be wrong though.

i think the EK10000G is the fastest fanless cpu that supports DDR1 from via.

edit: let me correct myself, it does have a fan. so i think the EK8000EG might be the fastest without a fan.

in addition: i think you would open up your options a lot if you were willing to use ddr2

Any Via C7 processor has a built in Encryption engine and should be plenty fine.

thats what i thought, but i couldn't find any info confirming it.

The C7-M features VIA's Padlock security co-processor, which is dedicated to encryption and unencryption duties. This should give the C7-M a boost in these CPU-intensive activities as compared to other lightweight mobile processors. The Padlock security co-processor is entirely specialized towards encryption, acting as an 'encryption accelerator' rather like a 3D card accelerates 3D video by taking the strain of vertex and pixel computation off the CPU. Some of its abilities include:

AES encryption at up to 25GB/s. The padlock supports all AES modes through the Padlock ACE (Advanced Cryptography Engine). This ability allows the C7-M processor to offload AES encryption tasks to the Padlock co-processor and avoid getting bogged down by this traditionally processor-intensive activity. The Padlock ACE does not require special software support to aid in AES encryption tasks.

Accelerated RSA encryption. RSA or Public Key encryption also involves significant mathematical calculations that can slow down the processor. The Padlock processor cannot entirely take over the process of RSA encryption as it can with AES, but it does incorporate 'Montgomery Multipliers' which speed up the necessary calculations.

SHA-1/SHA-256 support. The Padlock can encrypt data with a secure hashing algorithm in real-time, placing a digital 'stamp' on everything processed. In theory, this should allow for tamper-proof document transmission to be carried out automatically, but software developers would have to build support for this into their applications first.

Dual hardware-based random number generators provide a foundation for the encryption processes that the Padlock co-processor carries out. The way these two generators work is kind of interesting. VIA's quantum Random Number Generators detect minute random variances in the frequency of the various system clocks and turn them into random numbers. Both RNGs are 'always on', generating random numbers constantly and providing them to the other components of the Padlock co-processor when needed.

aha nice thx nnstep thats what i wanted to know. couldn't figure out how the guy did it with his C7 (i saw a guy make a similar thing but then with 4 Wireless cards and dual 2W amps to listen to 300 networks at the same time and log/get the WEP passcodes etc)

I thought it had the encryption engine but wasn't sure. one of my main reason to go via now.
