Hi,

For those of you who don't know it yet, a BOINC distributed project was set up to help sieving the keys.

We currently have 100 CPU cores registered, we need more!

Please join , you can help us in 3 clicks under windows and linux :biggrin:

http://boinc.unsads.com/rsals

Would it be interesting to add other keys? Now we have all ti68ks and k0A.

You have a nice computer there.

bobti89 has added to his ZIP the six .poly posted above by fullmetalcoder, and the k0A.poly of the other thread. You can work on whatever key you wish to work on: TI-68k keys (keyti89, keyti89t, keyti92p, keyv200), TI-Z80 keys ("01", "02", "03", "08", "0A", "0101" and "0102") Smile
It seems that the efforts are currently concentrated on the "0A" TI-Z80 key, see http://www.unitedti.org/index.php?showtopic=8899 .

The "0x" keys are for OS signing, the "010x" keys for app signing. 1 = TI-92+, 2 = TI-73, 3 = TI-89, 4 = TI-83+, 8 = V200, 9 = Titanium, A = TI-84+.

so 01, 03 and 08 cannot be considered as z80 keys right? and if these were already available in rabbitsign why was all the discussion above (about finding 68k keys) even necessary? I am probably missing something here. Can somebody enlighten me?

Just downloaded BOINC to help, but it seems like the project is out of work units.

yes it is, I'll add even more workunits tomorrow, I was on vacation.

The number of users tripled during the weekend, and so did the computation speed, so the 5000 workunits I added last friday have been quickly depleted ^^

Had a slight problem with the BOINC client at work. I thought it was calculating, but all 5-8 work units I "completed" were sent in and were pronounced "bad". Just wanted to give a heads-up, so the head of the project can take the necessary steps (if any). They were submitted by Synthesis2k2. My bad. :(

According to this, you've got some kind of permission error, so you have not actually been doing any work.

CreateProcess() failed - A required privilege is not held by the client. (0x522)
Does anyone have any ideas why this might happen?

I have none.

But I'm glad to see the BOINC dispatcher created another result (unsent yet) to conclude the validation:
http://boinc.unsads.com/rsals/workunit.php?wuid=3901

That's nice to see that this sort of problem is taken care autonomously, I was afraid we would have to resend particular workunits to complete the failed ranges Smile

Well, thankfully its taking care of the trouble units I messed up. I'll probably start this up on my home computer tonight or tomorrow, where I know exactly what privileges I have and what I don't. Thanks guys.

Well, it will be time to add other keys to the system.

Lionel proposed the '0102' key with the following polynomial:


Code:

is it okay to use this one?

(note: there's no more boinc jobs at this time, I'm aware of this, some more are to come in the next hours. However there are 4000 jobs in the wild so far so on average each machine has ~10 jobs to complete before complaining)

Between 02 and 0102, I think we should start with 0102, because 0102.poly (from polys.tar.gz) has a Murphy score of 2.70e-12 (good score is 2.16e-12), while 02.poly has a Murphy score of 2.39e-12.
I can't do that myself right now because I have a number of BOINC WUs queued, but I guess the polynomial selection for 02 could be pushed up to 20M leading coefficients ?

My PC isn't busy right now, so I guess I'll work on 02 polynomials.

What about the 68k application keys? Any interest there?

Yes, we have a nice number of relations, around 30 millions now.

I've stopped counting regularly because wc -l is quite long to count lines in ~ 3GB*5 of files Very Happy
I'll run it tomorrow however, to check the counts.

FYI: http://boinc.unsads.com/rsals_data/allstats.PNG

If you have time and space to backup the results in this directory, don't hesitate to do so. There are tarballs for boinc results, and "preboinc" files.

Besides the tarballs, one can make incremental backups of all individual BOINC result files for the "0A" key and the TI-68k OS keys by using e.g.:

mkdir -p 73FA ; cd 73FA ; wget -O - http://boinc.unsads.com/rsals_data/list_73FA | awk '{print "http://boinc.unsads.com/rsals_data/73FA/" $0}' | wget -nc -i - ; cd ..

mkdir -p 84P ; cd 84P ; wget -O - http://boinc.unsads.com/rsals_data/list_84P | awk '{print "http://boinc.unsads.com/rsals_data/84P/" $0}' | wget -nc -i - ; cd ..

mkdir -p 89 ; cd 89 ; wget -O - http://boinc.unsads.com/rsals_data/list_89 | awk '{print "http://boinc.unsads.com/rsals_data/89/" $0}' | wget -nc -i - ; cd ..

mkdir -p 89T ; cd 89T ; wget -O - http://boinc.unsads.com/rsals_data/list_89T | awk '{print "http://boinc.unsads.com/rsals_data/89T/" $0}' | wget -nc -i - ; cd ..

mkdir -p 92P ; cd 92P ; wget -O - http://boinc.unsads.com/rsals_data/list_92P | awk '{print "http://boinc.unsads.com/rsals_data/92P/" $0}' | wget -nc -i - ; cd ..

mkdir -p V200 ; cd V200 ; wget -O - http://boinc.unsads.com/rsals_data/list_V200 | awk '{print "http://boinc.unsads.com/rsals_data/V200/" $0}' | wget -nc -i - ; cd ..

(if you have a high-bandwidth connection, you may want to pass --limit-rate=<n> to the wget on the receiver side of the pipe, so as to make the server's life a bit smoother Very Happy)

[EDIT1: fix a typo.]



As for the TI-68k FlashApp keys: I have identified five call sites of BN_power17Mod in AMS 2.01, 2.05 and 3.10 (the OS itself, not the boot code). Four of them are rather close to each other, the address of the fifth one varies widely. But I haven't yet investigated further (I mean, retrieving their third argument).
Some clues can probably be found by executing Flashappy, which makes Flashapp signature validation ineffective by modifying the OS code. But for now, I'm going to bed :)



[EDIT2, 20090823: add the 73 FlashApp (0102) folder; use -nc instead of -N for wget, it's more efficient because the folders are in add-only mode.]

As I think I've mentioned before, I've already found (by analyzing existing app signatures) what I believe to be the public keys for signing TI-89/92+ Flash apps. They are:

Key 0101 (TI-92+ / V200):
BC747C4065E96E3B79B9BCC1A441BC3692E264CF681C9962B763C19824D84FB0474D567CF2FE5547
3378A18DB2E875BCE87F0022B6B9CC1E1FD455D9FACD0461

Key 0103 (TI-89 / Titanium):
916BDE593CC9F21B07F72033A92D6DC6DCCE8622705E9F7B4C4235A00B0A0DEA4F9827960CF2676C
3F25F987C4BACD38A8F849A5CFCEC188BA0C8B3DFD3602ED

Someone with an actual ROM dump should confirm these numbers. They are probably stored in the boot code, somewhere near where the OS keys are stored.

Edit: Never mind, they are stored in the OS upgrade itself. Offset 0x39BA6 in os209.9xu, 0x39F66 in os209.89u. I think it's fair to assume these are the actual keys.

I don't know if there are also 0108 and 0109 keys; I haven't seen any apps signed with those keys. Like 010A, those keys would not be particularly useful.

Indeed, it's fair to assume these are the actual keys. Good job :)

On 89, 89T, 92+ and V200, 0101 and 0103 are stored right after the timestamp key (A3E3..1E15).
They're indirectly referenced by a move.l #32-bit,(a2), a2 being an output area of that routine (this is AMS 2.05 for 92+):

Code:
__L44A996:
link.w %fp,#-104           /* [0x44A996 (4499862)] 4e 56 ff 98      */
movem.l %d3/%a2-%a3,-12(%fp)  /* [0x44A99A (4499866)] 48 ee 0c 08 ff f4 */
movea.l 8(%fp),%a2         /* [0x44A9A0 (4499872)] 24 6e 00 08      */
[...]
pea __L449C74(%pc)         /* [0x44AB8C (4500364)] 48 7a f0 e6      */ -> this points to 01 01 or 01 03.
move.l -54(%fp),-(%sp)      /* [0x44AB90 (4500368)] 2f 2e ff ca      */
jsr __L531FB0 /* tios::memcmp *//* [0x44AB94 (4500372)] 4e b9 00 53 1f b0 */
addq.l #8,%sp             /* [0x44AB9A (4500378)] 50 8f          */
tst.w %d0                /* [0x44AB9C (4500380)] 4a 40          */
bne.s __L44ABFC /* 0x5c */   /* [0x44AB9E (4500382)] 66 5c          */
move.l #4496436,(%a2)       /* [0x44ABA0 (4500384)] 24 bc 00 44 9c 34 */
moveq #64,%d0             /* [0x44ABA6 (4500390)] 70 40          */
move.l %d0,4(%a2)          /* [0x44ABA8 (4500392)] 25 40 00 04      */
bset #4,29(%a2)            /* [0x44ABAC (4500396)] 08 ea 00 04 00 1d */
move.w #1,%d0             /* [0x44ABB2 (4500402)] 30 3c 00 01      */
bra.s __L44ABFE /* 0x46 */   /* [0x44ABB6 (4500406)] 60 46          */


One of the two callers of that routine does:

Code:
lea -30(%fp),%a1           /* [0x447B4C (4488012)] 43 ee ff e2      */
move.l %a1,(%sp)           /* [0x447B50 (4488016)] 2e 89          */
pea -72(%fp)              /* [0x447B52 (4488018)] 48 6e ff b8      */
jsr __L44A996(%pc)         /* [0x447B56 (4488022)] 4e ba 2e 3e      */
[... calls MD5Init, MD5Update (*2) and MD5Done, cread, and most of all:]
__L447BF0:
movea.l -72(%fp),%a1        /* [0x447BF0 (4488176)] 22 6e ff b8      */
subq.l #1,%a1             /* [0x447BF4 (4488180)] 53 89          */
move.l %a1,(%sp)           /* [0x447BF6 (4488182)] 2e 89          */
movea.l -34(%fp),%a1        /* [0x447BF8 (4488184)] 22 6e ff de      */
subq.l #1,%a1             /* [0x447BFC (4488188)] 53 89          */
move.l %a1,-(%sp)          /* [0x447BFE (4488190)] 2f 09          */
pea -433(%fp)             /* [0x447C00 (4488192)] 48 6e fe 4f      */
jsr __L4204C8 /* tios::BN_power17Mod *//* [0x447C04 (4488196)] 4e b9 00 42 04 c8 */


i.e. the 0101 / 0103 key is passed as third argument to BN_power17Mod.


AMS 3.10 for V200 doesn't have a 0108 key, but AMS 3.10 for 89T has a 0109 key:

Code:
__L868790:

Polynomial selection on 0101 was already performed on more than 20K leading coefficients, yielding a 2.83e-12 Murphy score. Given that I don't have many BOINC WUs in queue, I guess I'll make my computer crunch away on 0103 this weekend :)


PS: screw dasm-tigcc for outputting immediate values in decimal representation !

well, let's add this key. The only thing I need is the polynomial.

I have started polynomial selection on 0103:

hem, by analyzing the outcome of the received results, it seems that the failure rate is very high (28.2099% for windows, much less for linux - 7.5463% ) and I know why.

Among the latest users registered, a lot of them participate in multiple projects. So the BOINC client has to stop calculations and my application cannot resume, because checkpointing is not implemented.

I would love if the author of GGNFS could behave as the msieve's one, and help us with this part. I don't know what has to be saved, when the backup has to be done, how to restore it, etc.

The global algorithm should be as follow:


Code:
start()

boinc_init()
if checkpoint file exists
  read it
else
  read input file

while(has_something_to_do)
  do_a_bit_of_work
  if( boinc_time_to_checkpoint())
   write the checkpoint file
   boinc_checkpoint_completed()

write output file
boinc_finish()

this improvement is MUCH more important and easy to deploy than the validator. (which I'm reluctant to switch in the middle of the project)
