Good morning Luke,
Another thing we can do with scan mode would be something like the below
masking:
input CLK, RESET_N;
input TESTMODE;
input SCANOUT_INTERNAL;
output SCANOUT_PAD;
reg gating;
wire n_gating = gating && TESTMODE;
always_ff @(posedge CLK, negedge RESET

If HUMAN_READABLE_TITLE is the additional secret, the user would need
to enter it on the device in addition to the nonce, wouldn't it defeat
the advantage in UX that was gained by using (relatively) short nonce ?
Is 64 bit nonce not enough ?
It seems that to crack this with fixed Pwd and 64 bit n

Thanks everyone who has provided inputs so far!
This is the new proposal for the encryption aspect of the scheme, based on
all the feedback.
The key derivation function would be PBKDF2, with PRF = SHA512. This should
be readily available on today's hardware already, as they are used for
BIP39.

Hard no to this idea:

As someone who has helped people find UTXO at key paths they didn't
know/want, this is a terrible idea. Key derivation paths should be
small, sequential integers,

Hi Jeremy,
If I understand correctly your concern, you're worried that change would
ease discovery of the node's tx-relay topology ? I don't scope transaction
origin inference, if you suppose the
unrequested-tx peer sending is the attacker it must have learnt the
transaction from somewhere else wh
