BIKE KEM implenetations on Arm Cortex-M4

There are 4 implementatins in 4 directories:

bikel1portable : BIKE level 1, implementation from BIKE team, adapted from supercop-20200906/crypto_kem/bikel1/portable/ .
bikel3portable : BIKE level 3, implementation from BIKE team, adapted from supercop-20200906/crypto_kem/bikel3/portable/ .
bikel1m4 : BIKE level 1, this work, modified from BIKE team's portable version.
bikel3m4 : BIKE level 3, this work, modified from BIKE team's portable version.

portablel1 and portablel3 were adapted from the BIKE team's portable implementation in SUPERCOP. Specifically, we changed line 29 and 30 in sampling_portable.c to

< uint32_t pos_qw[MAX_WLIST_SIZE];
< uint64_t pos_bit[MAX_WLIST_SIZE];
from

size_t pos_qw[MAX_WLIST_SIZE];
size_t pos_bit[MAX_WLIST_SIZE];

The original implementation presumed size_t a 64-bit data type, which is not true in 32-bit machines.

Download and Setup benchmarking environment for PQM4 from https://github.com/mupq/pqm4 .
Copy the imple/ directory to pqm4/crypto_kem/your_desired_name/ . For example,
'cp -r crypto_kem/bikel1m4 pqm4/crypto_kem/bikel1m4'
assuming the PQM4 is installed in the pqm4 directory.
Use standard tester on PQM4 for the implementation you copied. For example, in the pqm4 directory, execute
'python3 test.py'
or
'make IMPLEMENTATION_PATH=crypto_kem/bikel1m4 bin/crypto_kem_bikel1m4_speed.bin; st-flash write bin/crypto_kem_bikel1m4_speed.bin 0x8000000' .
Then collect benchmark results from the UART port of your M4 board with tools from PQM4 .
