Reference implementation
========================
This folder contains the reference implementation for Lilliput-AE.
It is organized as follows:
`src`
-----
Contains parameter-independent code for the reference implementation:
- `lilliput-ae.h`: main API
- `lilliput-ae-i.c`: implementation of Lilliput-Ⅰ (ΘCB3-based)
- `lilliput-ae-i.c`: implementation of Lilliput-Ⅱ (SCT-2-based)
- `ae-common.h`: internal helper functions used by both AE schemes
- `tweakey.*`: implementation of Lilliput-TBC's tweakey schedule
- `cipher.*`: implementation of the tweakable block-cipher
Lilliput-TBC
- `constants.*`: tabulated data for
- the tweakey schedule's permutation h
- the tweakey schedule's multiplication sequences P~0~ to P~5~
- Lilliput-TBC's S-box
- `parameters.h`: byte sizes for inputs and outputs (depends on
parameter-dependent `_parameters.h` files)
Also contains some support files:
- `common.mk`: Makefile recipes to compile and test the implementation
- `debug.h`: helper functions to ease debugging and dump intermediate
values
