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

Age	Commit message (Collapse)	Author
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	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.
2018-09-11	Adding a huge, self testing test case.	Joachim Strömbergson

2018-09-07	Updated testbench to use the new API. Verified that the new API works. No ↵	Joachim Strömbergson
	more banks.
2018-09-07	Removed r_bank from dump since it no longer exists.	Joachim Strömbergson

2018-09-07	Test write to all positions in the mem.	Joachim Strömbergson

2018-09-04	Updated rtl and tb to support parameterized memory size.	Joachim Strömbergson

2018-09-04	Updated testbench to handle parameterized core.	Joachim Strömbergson

2018-09-04	Updated testbench to work with the parameterized memory.	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.
2018-08-15	Fix some misleading messages, and enable all tests.	Paul Selkirk

2018-07-24	Added explicit width specification for constant to silence truncation warning.	Joachim Strömbergson

2018-07-06	(1) Updated version to reflect status. (2) Minor fix after running sim in ↵	Joachim Strömbergson
	ModelSim.
2018-07-06	Adding test case for 4096 bit unwrap. Testcase passed! We have unwrap.	Joachim Strömbergson

2018-07-06	Debugged key unwrap. First testcase for unwerap passed. Added some more ↵	Joachim Strömbergson
	debug outputs.
2018-07-06	(1) Fixed dump of core_addr in testbench to actually show the core_addr. ↵	Joachim Strömbergson
	Fixed boundaries for the block counter. Now we don't read mem out of bounds.
2018-07-05	Adding wait state to allow access from memory to complete. Should be ↵	Joachim Strömbergson
	possible to optimize.
2018-07-05	Fixing block counter init bug. Enabling detailed debugging. Fixing minor nits.	Joachim Strömbergson

2018-07-05	Fixed minor details in unwrap test case. Enabled unwrap test case.	Joachim Strömbergson

2018-07-05	Updated keywrap logic to support unwrap. Split state to handle next start in ↵	Joachim Strömbergson
	both wrap and unwrap cases.
2018-07-05	Adding state and counter functionality to support unwrap. Changed name of ↵	Joachim Strömbergson
	define to something more comprehensible.
2018-07-05	Adding unwrap test case.	Joachim Strömbergson

2018-07-05	Adding wrap test case with 4096 bit plaintext from NIST. Test result matches ↵	Joachim Strömbergson
	model.
2018-07-05	Removed a few states and a few cycles.	Joachim Strömbergson

2018-07-05	Adding tool to generate write commands.	Joachim Strömbergson

2018-07-05	Adding testcase for wrapping 4096 bit data.	Joachim Strömbergson

2018-07-05	We haz keywrap! Time to add more testcases and make them self testing. Oh ↵	Joachim Strömbergson
	and implement unwrap.
2018-07-05	Debugged keywrap processing including A update. All AES operations works ↵	Joachim Strömbergson
	correctly. Now we just need to stop processing whe we should.
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.
