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.
2019-01-29	Updated README to current status. Added section about the auto zeroise ↵	Joachim Strömbergson
	functionality that has been merged. Moved sections around to be in a (hopefully) more pedagogical order.
2019-01-17	Added non-zero default timeout value in core. This fixes the keywrap ↵	Joachim Strömbergson
	problems by not automatically reset the key in the API. Enabled all testcases and disabled excessive debug outputs.
2019-01-17	Debugging keywrap after auto_zeroise. Now the core starts processing as ↵	Joachim Strömbergson
	expected.
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	Add testcase that verifies forced zeroisation.	Joachim Strömbergson

2019-01-11	Adding test case that verifies that SW can keep a key alive by reading ↵	Joachim Strömbergson
	status register.
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.
2018-12-20	valid should not be set from reset. There is no valid data.	Joachim Strömbergson

2018-12-20	Cleaned up and made auto zeroise test case 1 self-testing:	Joachim Strömbergson

2018-12-14	Splitted the auto-zeroise test case into three separate tests.	Joachim Strömbergson

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

2018-12-11	Adding test case for auto_zeroise. Can see that a loaded key gets wiped ↵	Joachim Strömbergson
	after timeout. Status bits looks fishy though.
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 untested code to implement timer controlled automatic zeroisation of ↵	Joachim Strömbergson
	key loaded into the aes core.
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.
2018-12-07	Solved event loop.	Joachim Strömbergson

2018-11-27	Adding test that tries to write a key into the serial memory.	Joachim Strömbergson

2018-11-27	Adding check that correct status word was written into the serial memory.	Joachim Strömbergson

2018-11-23	Added ability observe mkmif state. Realized that the write operation handler ↵	Joachim Strömbergson
	was under read operation handling. Fixed this and now status write works. We can observe 0xdeadbeef in the memory after status write operation.
2018-11-23	Updated display of states. We can now observe correct init of the memory.	Joachim Strömbergson

2018-11-23	Adding task to dump parts of the contents of the serial memory.	Joachim Strömbergson

2018-11-23	Added observation of mem internal control states.	Joachim Strömbergson

2018-11-23	Enabled spi observation and can see that SPI interface is alive when pulling ↵	Joachim Strömbergson
	init.
2018-11-23	Adding test case for mem init. Removing auto-load test case since the dut ↵	Joachim Strömbergson
	does not support auto load. Updating the write status test case to use wait_ready() for dut status.
2018-11-23	Adding vendor mem model.	Joachim Strömbergson

2018-11-22	Adding outputs to observe dut API. Adding support in Makefile for using the ↵	Joachim Strömbergson
	vendor supplied memory model.
2018-11-13	Adding README that describes the purpose of the dir and how to get the ↵	Joachim Strömbergson
	vendor specific memory model we need here.
2018-11-06	Fixed incorrect address used for the key. Added testcase to verify reading ↵	Joachim Strömbergson
	of status word.
2018-11-06	Trigger read operation when we should read.	Joachim Strömbergson

2018-11-06	Adding test case to observe auto-load of key and status after reset.	Joachim Strömbergson

2018-10-30	Integrated the DUT into the testbench and update Makefile to build the sim ↵	Joachim Strömbergson
	target-
2018-10-23	Hardened the keywrap API to not allow reads or writes when the core is busy.	Joachim Strömbergson

2018-09-28	Adding initial version of testbench for the mkmif wrapper.	Joachim Strömbergson

2018-09-28	Completed syntax debug after integration of new mkmif_core wrapper.	Joachim Strömbergson

2018-09-28	Integrated new mkmif_core wrapper.	Joachim Strömbergson

2018-09-28	Some whitespace cleanup.	Joachim Strömbergson

2018-09-28	Completed the functionality that should be in the wrapper. Now its just ↵	Joachim Strömbergson
	debugging...
2018-09-28	Got all states needed. Added hold registers for address and data to be written.	Joachim Strömbergson

2018-09-28	Adding initial version of mkmif wrapper used by keywrap_core to hide ↵	Joachim Strömbergson
	protocol complexity.
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.
2018-09-25	Increased control state space to make room for read and write operations.	Joachim Strömbergson

2018-09-25	Integrate the mkmif_core instead of the mkmif wrapper.	Joachim Strömbergson

2018-09-21	Adding more infrastructure needed for the integrated mkm.	Joachim Strömbergson
