NAND VTRM Structure

Overview: A good way to understand the structure is to think in how the vtrm is created, there are 3 main processes where are written the 'magic_vtrm' sections (colored in black in the examples), in general lines can be said the 'magic_vtrm' sections are created "from bottom to top". This explain doesnt includes the processes needed to create the first 'magic_vtrm' section

At some point that should be considered the "initial state" is performed an "erase" command from 0xEC000 up to 0xF0000 (0x200 blocks are filled with 0xFF's). After that the first 2 blocks are reserved (from 0xEC000 up to 0xEC400). The creation process starts at the third block (at offset 0xEC0400), this section where is used for first time the 'magic_vtrm' can be considered the most "inner" vtrm, or the most older in the creation process

After that 'inner' vtrm is created (how is created is out of the explain) then the creation process returns to the first block (the area that was reserved before from 0xEC000 up to 0xEC400), most of the steps made to create this area consists in copying and indexing other areas of the 'inner' vtrm

So now the creation process is going to build the first 2 blocks... but the first 0x10 bytes of the first block (from 0xEC0000 up to 0xEC0010) are ignored at this point, the reason why are not created yet is because is not posible to know the amount of bytes that are going to be copyed below it in the next steps (now is going to start a process of copypasting at offset 0xEC0010)

This is when starts a process that im going to label the 'copypaste' that starts at offset 0xEC0010 and does three things, first it creates a value of 0x8 bytes (colored in green in the examples) with an offset that points to the 'inner' vtrm, then another value of 0x8 bytes (colored in green in the examples) that indicates how many bytes are going to be copypasted, then the bytes are copypasted below

This copypaste is made 3 times. The first one copypastes the VTRM header (the bytes from 0xEC0400 up to 0xEC0428 are copypasted to 0xEC0020 up to 0xEC0048). The second copypastes one of the encrypted data areas (the bytes from 0xEC2980 up to 0xEC29E0 are copypasted to 0xEC0058 up to EC00B8), for some reason i dont get now it "jumps" 0x40 bytes, and then it does another copypaste that works a bit different

In the third copypaste, the value that indicates the offset points to the 'exception' hash inside the hash_table (bytes from 0xEFE68C up to 0xEFE6A0 are copypasted to 0xEC0108 up to 0xEC011C), but instead of copying the 'exception' hash it copypastes the default hash value

At this point the creation process is near completed, the only thing left is to fill the 0x10 bytes at the beginning in the first vtrm block (at 0xEC0000), this small area is going to work as the entry point when reading the whole vtrm, and this is when is written the 'magic_scei' that is unique (is the only value from this blocks in common between NAND and NOR), the other thing that indicates this area (with the value 0xA8) is the lenght of the areas that has been copypasted below (but only the sum of the first two copypastes, for some reason the third copypaste is not included in this sum, also the position where the third copypaste happens is a bit weird i dont get why that position, is because the 0x40 gap but that gap makes no sense, the point is the gap is there and is related with the reason why the third copypaste to not be included in this sum)

---

The offsets used to make the copypastes in the first 2 blocks are absolute, this means is needed to start counting from outside of the vtrm, actually from the start of flash. When looking at a flash dump from inside a hexeditor, or here in wiki examples what we see is the whole flash data, but this view is not the logical map. The flash region starts at the Flashregion Table, at the absolute offset 0x40200

• For this reason is needed to add + 0x40200 to the offsets that appears inside vtrm to know where are pointing
  • 0xE80200 + 0x40200 = 0xEC0400 (inner VTRM start offset)
  • 0xE82780 + 0x40200 = 0xEC2980 (prototype encrypted data ofset)
  • 0xEBE48C + 0x40200 = 0xEFE68C (exception in the hast_table)

VTRM hashes and how to generate them

repeated hash -> hmac sha1 using srk of an empty string ("")
hidden hash -> hmac sha1 using srk of 0x58 bytes of empty encrypted data using keyseed_for_srk
header hash -> hmac sha1 using srk of hmac sha1 using srk of header table without header (0x28 bytes) and signature table.

Extra hashes

srh -> hash of signature table (big table with repeated hashes and hidden hash)
