Michael Cardell Widerkrantz	08e1438d1e	fw: Add support for blake2s MMIO ... In firmware we store the address to firmware blake2s() function at TK1_MMIO_TK1_BLAKE2S so app can use this firmware function sort of like a system call but without context switch.	2022-12-15 12:59:52 +01:00

Michael Cardell Widerkrantz	c80dc53027	fw: Introduce an explicit state machine - changes protocol! ... We introduce an explicit state machine (see README). With the new states we: - combine setting size and USS to a single command. - start the device app immediatiely when having receceived the last data chunk and returning the digest. - Loop forever and wait for the stick to be removed if we end up in unknown state.

Michael Cardell Widerkrantz	490571b6c0	Clear all RAM during start ... Since SRAM has some data remanence even without power it seems good hygien to clear all RAM when starting the device so as not to leak potential sensitive data between device apps.	2022-10-24 11:52:52 +02:00

Michael Cardell Widerkrantz	cbe6d3db8d	Use the new firmware-only RAM for CDI computation ... To protect UDS we use a special firmware-only RAM for both the in parameter to the blake2s() function and for the blake2s_ctx.	2022-10-18 14:51:30 +02:00
Michael Cardell Widerkrantz	6d08a82c05	Pass the blake2s_ctx to blake2s() as arg ... Instead of allocating the blake2s_ctx in the blake2s() function we pass it as a pointer as an argument to be able to better control where the variable is in memory.	2022-10-18 14:51:26 +02:00

Daniel Lublin	55c5081486	Adjust and document the firmware state-machine, including USS ... In particular, order of LOAD_USS and LOAD_APP_SIZE is not required, but the need to send both is documented. This is followed up with adjustment in the host programs' Go code, to try to reinforce this. LoadApp() will take the secretPhrase parameter (to be hashed as USS), and loadUSS() will be unexported. Correct CMD/RSP lengths in pseudo-code.	2022-10-12 15:12:07 +02:00
