core/util/keywrap - AES KEY WRAP as defined in RFC 3394

Age	Commit message (Collapse)	Author
2020-04-29	Finally got integrate_mkmif working.HEAD master	Paul Selkirk
	Wired up mkey_key to allow the user to specify which key to use (MKM or user-provided key). Wired up mkm_wr_status so we can actually write the status word to MKM. Removed the reset initialization of mkmif_core, since that has its own auto-initialization. I might want to remove init as an input to keywrap_mkmif. Fixed a FSM state-transition write-enable, so it would actually transition states. Changed a 3-bit counter to 4 bits, so it can actually count to 8. And removed several bits of non-functional junk.
2020-03-31	Merge branch 'integrate_mkmif' to master	Paul Selkirk

2020-03-25	Move keywrap from user/js to core/util.	Paul Selkirk
	Also remove the auto_zeroise code, since that's behaving badly, and it's not used anyway in the integrate_mkmif branch.
2019-01-17	Adding key timeout output port to allow core to inform the top level wrapper ↵	Joachim Strömbergson
	that timeout has occured. Added functionality to zeroise API key registers when timout has happened. Updated all auto_zeroise test cases to check that API key registers are properly zeroised.
2019-01-11	Fixed parameterized widths.	Joachim Strömbergson

2019-01-08	Adding the same API hardening to keywrap as implemented for other cores ↵	Joachim Strömbergson
	after the Cryptech audit.
2018-12-13	Fixed some bugs in auto-zeroise functionality. Now it really zeroises key ↵	Joachim Strömbergson
	automatically. It seems to work, but needs a bit more testing.
2018-12-11	Zeroisation of wrapper key registers. Adding reset of key_loaded register.	Joachim Strömbergson

2018-12-09	Adding support for SW to keep loaded key alive by reading status. Adding ↵	Joachim Strömbergson
	support for SW to trigger zeroisation of a loaded key.
2018-12-07	Adding a more sane default timeout value.	Joachim Strömbergson

2018-12-07	Adding API support for key loaded status and key timeout control. Added ↵	Joachim Strömbergson
	ports in the core to support key status and timeout. Updated core testbench to match the new interface.
2018-10-23	Hardened the keywrap API to not allow reads or writes when the core is busy.	Joachim Strömbergson

2018-09-25	Added logic to perform status word read operation from the mkm. Adding ↵	Joachim Strömbergson
	interfaces and registers to be able to pass mkm status to host. Updated dut instantiation in core testbench to.
2018-09-25	Updated the keywrap API to support access to MKM status. Updated ↵	Joachim Strömbergson
	keywrap_core to support control of MKM access operations.
2018-09-18	Adding API control bits to read and write key.	Joachim Strömbergson

2018-09-18	Moved compile time debug access control of key to the API. Added correct ↵	Joachim Strömbergson
	code to mux key.
2018-09-18	Moved the mkmif instance into the core itself. Added API to read the key if ↵	Joachim Strömbergson
	DEBUG is set.
2018-09-14	Adding instatiation of the mkmif in the keywrap top level wrapper. Updated ↵	Joachim Strömbergson
	testbench anf Makefile to build with instantiated mkmif. The mkmif is not yet used by the keywrap.
2018-09-04	Updated rtl and tb to support parameterized memory size.	Joachim Strömbergson

2018-08-24	We probably want to be able to read data too.	Joachim Strömbergson

2018-08-24	Killed the bank switching.	Joachim Strömbergson

2018-08-24	Performed Verilog parameter magic to make the design scaleable in terms of ↵	Joachim Strömbergson
	capacity. Does not yet work, but at least the linter is fairly happy.
2018-08-23	Adding top level defines for setting size and address bits.	Joachim Strömbergson

2018-08-16	Adding delay cycle to API regs to match the latency for accessing the ↵	Joachim Strömbergson
	blockRAM. Added test case that checks access to the API regs.
2018-07-06	(1) Updated version to reflect status. (2) Minor fix after running sim in ↵	Joachim Strömbergson
	ModelSim.
2018-07-05	Fixed memory word order. Fixed a number of bugs. First block encrypted ↵	Joachim Strömbergson
	correctly. A state is wrong and memory is read too far.
2018-07-05	Removed the streaming interface in favor of a normal address based ↵	Joachim Strömbergson
	interface. A bit more kludgy, esp since we need to use bank switching to be able to provide enough address space. But this removes a possible problem of the streaming address counter running wild.
2018-07-03	Good news: The core peformcs all AES operations and stops after correct ↵	Joachim Strömbergson
	number of operations. Bad news: All values are wrong.
2018-07-03	Debugged a lot of minor errors and added a lot of debug functions. Things ↵	Joachim Strömbergson
	are starting to work. As in AES is actually initialized and used.
2018-06-29	Fixed bugs in the API decoding logic.	Joachim Strömbergson

2018-06-29	Changed name in API for A words to clarify their meaning. Corrected case ↵	Joachim Strömbergson
	order in API logic.
2018-06-28	Adding a lot of functionality. Starting to get everthing in place.	Joachim Strömbergson

2018-06-28	A lot of cleanup of interconnections between cores and hierarchy. Fixed a ↵	Joachim Strömbergson
	number of nits and bugs. Added address generator for the API.
2018-06-28	Interface debugging.	Joachim Strömbergson

2018-06-28	Updated top level wrapper to better match the planned API. Updated core ↵	Joachim Strömbergson
	interface. Connected core into the top level wrapper.
2018-06-27	Adding initial version of top level wrapper for the keywrap core.	Joachim Strömbergson
