| 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 | 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 | |
| 2018-12-13 | 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 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. | |||
| 2018-09-04 | 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. | |||
| 2018-07-24 | 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 | 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 | 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 | Removed a few states and a few cycles. | 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. | |||
| 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 nits found during linting. | Joachim Strömbergson | |
| 2018-06-29 | Fixed bugs in the API decoding logic. | Joachim Strömbergson | |
| 2018-06-29 | Completed first version of core that should have all functionality needed to ↵ | Joachim Strömbergson | |
| do key wrap. | |||
| 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 | |
| 2018-06-26 | Adding more functionality in the core. Updated Makefile to build and ↵ | Joachim Strömbergson | |
| simulate with the AES core. Minor update to header and README. Clarified that it is RFC 5649 we are implementing. | |||
| 2018-06-22 | (1) Added initial version of keywrap_core which will implement the actual ↵ | Joachim Strömbergson | |
| wrapping using aes_core and the keywrap_mem. (2) Minor cleanup to the keywrap_mem code. | |||
| 2018-06-21 | Increased size of memory to 64 kByte to match what is needed for key wrap. ↵ | Joachim Strömbergson | |
| No problems. | |||
| 2018-06-21 | Reworked code a bit to match what ISE expects to map to block RAM instances. | Joachim Strömbergson | |
| 2018-06-21 | Implemented test design for key wrap memory. To be tested in ISE. | Joachim Strömbergson | |
| 2018-06-19 | Adding initial version of repo and design for core implementing aes key wrap. | Joachim Strömbergson | |
