Editing Flash:Encrypted Individual Data - eEID

== Encrypted Individual Data - eEID ==

eEID certainly stands for encrypted EID as each section eEID embeds is encrypted. EID certainly stands for Encrypted Individual Data. Why two 'e' in eEID ?

EID is the equivalent of IdStorage on PSP and PSVita.

eEID is decrypted by metldr and is passed over to the isolated loader which may pass it to a SELF. We can see this in graf_chokolo’s original payload.

It is 0x10000 bytes in size (64 kB) but only the first 0x1DD0 bytes are used. The rest is padded with 0xFF.

It is composed of 6 sections numbered from 0 to 5.

eEID contains per-console data like Console Id, OpenPsId, BD drive information and some keys.

==== Typical EID entry addresses and lengths ====

Entry point listed is offset from base EID address (NOR:0x002F000 / NAND:0x0080800 in these examples).

Absolute start address is base EID address + Entry point

Absolute end address is base EID address + Entry point + Length

Individual info Manager can write to EID0. Appliance Info Manager can rehash it.

EID0 embeds many (usually 11) AES128CBC encrypted sections. Each section is a IDPS Certificate.

We do not have all EID0 sections enc/dec key seeds:
<pre>
section 0 (PS3 cert keyset 0) -> yes
section 1 (PS3 cert keyset 1)-> missing
section 2 (PS3 cert keyset 2) -> missing
section 3 (PS3 cert keyset 3) -> missing
section 4 (PS3 cert keyset 4) -> missing
section 5 (PS3 cert keyset 5) -> missing
section 6 (PSP cert keyset 1) -> yes
section 7 (PSP cert keyset 2) -> missing
section 8 (PSP cert keyset 3) -> missing
section 9 (PSP cert keyset 4) -> missing
section 0xA (PSP cert keyset 5) -> yes
</pre>

Keys for EID0 sections 0, 6 and 0xA key seeds were found in secure modules, for instance seeds for 0 and 0xA in aim_spu_module, seed for 6 in pspemudrm.

====== EID0 section 0-5 crypto ======

* [https://web.archive.org/web/20141118233713/http://pastie.org/6169158 naehrwert's EID0 section 0 ECDSA signature verification]

====== EID0 sections 6-0xA crypto ======

EID0 section 6 is used in the PSP emulator by the DRM crypto engine to retrieve PSID. EID0 section 0xA is used by aim_spu_module to retrieve OpenPSID.

These sections' certificates uses PSP certificate keyset. It corresponds to PSP KIRK commands 0x10, 0x11 and 0x12 for verification of IdStorage Certificates. See also [[http://wololo.net/talk/viewtopic.php?p=20715#p20715]] and PSP wiki for PSP crypto stuff.

====== Note ======

On PS3 it uses ECDSA curve VSH type 2 with the PSP IDPS Certificates, whilst it uses a different curve with the PS3 exclusive IDPS Certificates (for example section 0). That is maybe how Davee and Proxima figured out the KIRK 0x10 and 0x11 ECDSA crypto keys. But not sure because their work was in 2011, not in 2012 (naehrwert) and it seems that PS3 uses a different seed for encrypting the ECDSA private key (see section 6 ECDSA private key seed).

=== EID1 ===

Used for individual SYSCON information.

==== Example ====

Here it is encrypted.

=== EID4 ===

Used for individual bluray auth information. See also [[BD Drive Reverse Engineering]].

EID4 contains two 128bit keys which are necessary to establish a secure communication channel to the BD drive for sending vendor specific security commands.

EID4 is encrypted with AES-CBC-256 algorithm.

=== EID5 ===

The largest and quite possibly the most important EID section of all 6. It's unknown what is inside this specific EID. We will probably never know without analyzing every possible clue about the PS3. And even then, it might be impossible to find its real use.

EID5 size is quite similar to EID0, but it has an additional 0x1A0 bytes. EID5 header has many similarities with EID0 header.
