Saber-PAKE-C

SABER is the 3rd round lattice-based candidate algorithm in the standardization process initiated for NIST (National Institute of Standards and Technology) public-key cryptosystems. This repository is the PAKE (password authentication key exchange) version of Saber.

Saber-PAKE's Performance Data

cycles/ticks data of Saber-PAKE parameter sets:

Algorithm	LightSaber		Saber		FireSaber
Process	Median	Average	Median	Average	Median	Average
c0	83 991	105 451	146 118	162 673	232 836	232 836
s0	94 458	100 739	162 489	170 159	255 237	278 094
c1	138 936	145 535	243 192	250 179	348 654	371 197
s1	41 802	44 412	59 391	63 862	80 820	86 409

The average time data (µs) of Saber-PAKE parameter sets:

Process	LightSaber	Saber	FireSaber
c0	44.039	67.939	102.735
s0	42.077	71.068	116.139
c1	60.785	104.488	155.021
s1	18.555	26.690	36.093

How to run Saber-PAKE

Saber provides 3 different security categories. (LightSaber 128-bit; Saber 192-bit; FireSaber 256-bit). These security levels are provided by the SABER_L variable in the "SABER_params.h" file.

#define SABER_L 2 /* LightSaber */
#define SABER_L 3 /* Saber */
#define SABER_L 4 /* FireSaber */
