Editing IDPS

 

The IDPS, also named ConsoleId or PSID, is a sequence of 16 bytes which is used as a unique per-console identifier for PlayStation consoles. The IDPS is stored and certified in [[Flash:Encrypted Individual Data - eEID|EID]].

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Product Code&nbsp;&nbsp;Product Sub Code

* 5th and 6th bytes represent the [[Product Code]]

* 7th and 8th bytes represent the [[Product Sub Code]] <!--// Note that CECHAxx is type 0x01 and CECHBxx is type 0x02 but they both have a COK-001 motherboard... (Changing 0x02 to 0x01 in CECH-B will enable wifi options in menu. But there is still missing hardware), and at the opposite... CECH-25xx models are type 0x0B but with 2 possible motherboards: JSD-001 or JTP-001//-->

<pre>

00 00 <- Unknown

00 01 <- Company (SCE)

00 89 <- Product Code: PS3, CEX, oceania

00 0B <- Product Sub Code: CECH-25xx (25xx series)

14 00 EF DD CA 25 52 66 <- Second half: factory code 5, no Ps Flag, serial number 61405, random stamp CA 25 52 66

== Dummy PSP IDPS in Kicho & Dengo Program ==

This is the dummy IDPS that is used by PS3 Reference Tool aim_iso when IDPS fails to be obtained from flash. That IDPS belongs to a Reference Tool DECR-1000A. The Reference Tool IDPS from above is static. PS3 CEX 3.55 does not have it.

Found in emulator_drm.sprx (iso self inside).

== IDPS second half ==

*Byte 8 bits 0-5: Factory Code

*Byte 8 bits 6-7 and bytes 9-10-11: Serial Number

*Byte 8 bits 6-7 and byte 9 bits 0-5: Ps Flags on PSP with Diag Factory Code

*Bytes 12-15: Random Stamp (guessed name). 3 theories: 1) totally random number, 2) hash of previous bytes (then there would exist at least 3 keysets), 3) encrypted timestamp.

== IDPS Regex ==

Based on 16 millions of PS3 IDPS dumps, on other PS consoles dumps and on IDPS structure.

<pre>0{7}10[012][089A][0123456789ABCDEF]00[0123456789ABCDEF]{18}</pre>

<pre>0{7}100[89A][0123456789ABCDEF]00[0123456789ABCDEF]{18}</pre>

== Serial flash ==

The PS3 IDPS can be found in serial flash, precisely in EID0 and EID5. See [[Flash:Encrypted_Individual_Data_-_eEID#EID0|Flash]] (NAND @ 0x80870 / NOR @ 0x2F070).

You can verify the IDPS of a PS3 console through 2 ways: PARAM.SFO of savedata or HDD backup from PS3 Backup Utility. You would need to bruteforce about 7 bytes, if you know the PS3 model.

Problem: "My old PS3 received the YLOD, however I have a hard disk drive backup of it, but I no longer have the actual unit, and I do have a new PS3. I want to recover all my data to my new PS3, but I need to be able to dump all the data from archive2.dat to create a fresh HDD backup with all the data to restore to my new PS3 unit. So I need to crack the IDPS used to encrypt the backup."

Solution (to test) by zecoxao: "Bruteforce the IDPS from the IDPS hash of a PARAM.SFO file (second hash iirc). You select your region and model and only have to bruteforce the last six bytes. If the scene could establish some kind of standard or bruteforce blueprint, like a blank PARAM.SFO of the PS3 SingStar application, which should look the same on every console, someone could even work on a rainbow table for IDPS. The easiest would be PARAM.SFO of savedata, by manually verifying a certain sha1-hmac made from the file PARAM.PFD with IDPS as key. I was just looking into that and made a small PoC in C#, which bruteforces my PS3 IDPS. But even with all optimizations (especially for C#) and running on all cores with parallelization it is not really that fast. Moreover, I even cheated and only bruteforced the last six bytes of my known IDPS. It is currently still running... Using openCL would help, because graphic cards are naturally faster than CPUs. Currently looking into that, but I never worked with openCL before and cannot even find a hmac/sha1 kernel for openCL. Like nobody every did that before ... ;) [https://searchcode.com/codesearch/view/45893397/ useful?]"
