Zebra RSA Bruteforce

Zebra RSA Brutforce

I'm not pretty sure what they are working on (RSA keys with Bruteforce method) all is in German... but it seems to be like TMRL DRTG

If its something like TMRL DRTG ill be in
Just need found somewhere some computer

BOINC.SK team created

On my P4 2,0G - WU about 100mins

[slavko.sk]

I don't have more computers ...... I have but can't run BOINC (about 16.000 servers - you can imagine how sad am I!!!!!!!!!!!)

buy some

more info on the project from admin:

Everything is about an RSA-Smartcard.
There is a Operating system on this Card.
This accepts only RSA-crypted applications. These Applications are protected by a checksum. This checksum is also crypted by an RSA key.

Known is the Key-pair for Applications, but NOT for the checksum.
There is no support anymore for this Smartcard.

We are trying to break the RSA-key for the checksum by Brute-forcing.

Goal:
With the Key we can upload own applications to the Smartcard or upload a new Oparating System

The key will be published. The Project origins from an idea in a forum.


The Modulus is 512bit long.
public exponent is known.

Second goal (for me an all interested people):
Understand RSA, primes and develope an effective Bruteforcer.
I am an Computer Sience student.


The BOINC-page isn't finished yet - i am a one-man show at the moment.
BOINC is new to me and i had some trouble setting the server up.

My DSL-connection is cut every 24h - so from time to time there can be connection problems.

Thank you for attending.

this project is really somef...think. one man show - hehe, i think, when S@H will be back i will detach my PC from this project for sure...

from homepage of Zebra :

The Project was published too early.



PS i think i will not continue at all

Version 0.13 is out! 100% faster than Version 0.10.
Testing phase!!! New accounts can be created, again. But at the moment there is the risk in not finding a problem-solution in lifetime.
Mathematical help is welcome.

No new WUs are created, because we can't gain higher speed with the Sieve of Ulam.
I am working on a GNFS Version. This will need some time...
