SABER is a Mod-LWR based KEM finalist in the NIST Post-Quantum Cryptography Standardization Process.

• AVX_Implementation_KEM : AVX2 optimized implementations of LightSaber, Saber, and FireSaber.
• Cortex-M_Implementation_KEM : Cortex-M optimized implementations of LightSaber, Saber, and FireSaber. Includes subdirectories Cortex-M0 and Cortex-M4.
• KAT : Known Answer Tests for all possible conbinations of {uniform}-{Fire, Light}Saber-{90s}.
  • PQCkemKAT*.req : input for Known Answer Test
  • PQCkemKAT*.rsp : output for Known Answer Test
• Reference_Implementation_KEM : Reference implementations of LightSaber, Saber, and FireSaber.
• Variants : Implementations of Saber variants: uSaber, Saber-90s, and SaberX4

• Select the desired algorithm in SABER_params.h. This can be done by commenting/uncommenting the appropriate line with #define in the code.
• Use make clean to clean executable files
• Use make all to compile the source codes
• Use ./test/test_kex to run KEM operations in loop for repeat number of iterations
• Use ./test/PQCgenKAT_kem to generate KAT files
