Fudan FM11RF005SH (512 bit)

Fudan FM11RF005SH , has 512bit mem,  16blocks w 4bytes / block.   Total 64bytes

ISO14443a,  with support REQA, READ, WRITE, AUTH.   Unknown how the auth is done.
Kind of similar to Ultralight tags.

In order to add support for it in PM3. ATQA/SAK and a trace from one of these tags would be intersting to look at.
I found a v1.1 of the datasheet but it doesn't explain the auth command very well. A full datasheet would be nice to have.

Re: Fudan FM11RF005SH (512 bit)

Key is stored in block 8.

Reader: 60 01
Card: Random1
Reader: (encrypted stuff) with its random2
Card: ??

read = 0x30
write = 0xA0
auth = 0x60

Memory layout
-------------------
Block0 = CID customer id / MID  manufacturer id
Block1 = UID
Block 8 = key


I doubt the communications is encrypted,  so a normal sniff of a transaction between card and valid reader should reveal much.

That's gonna be tough since you might be a stranger while using proxmark3 near the gate of subway.

According to this document, Fudan Microelectronics makes two similar chips with 512 bits of memory, one with Mifare compatible crypto and the other "compatible with Shanghai local standard"


Those who forget the past are doomed to repeat it.
