Supported XMSS Algorithms

XMSS includes a various set of algorithms that are different by WOTS+ parameter (n, w, len) and the XMSS tree height (h).

Here you can find the actual set of XMSS parameters and how they map to the enum.

Syntax

typedef enum
{
    reserved = 0,
    XMSS_SHA2_10_256 = 1,
    XMSS_SHA2_16_256 = 2,
    XMSS_SHA2_20_256 = 3,
    XMSS_SHA2_10_512 = 4,
    XMSS_SHA2_16_512 = 5,
    XMSS_SHA2_20_512 = 6
} IppsXMSSAlgo;

Table of values

reserved is not expected to be used.

Name	SHA Function	n	w	len	h
XMSS_SHA2_10_256	SHA2-256	32	16	67	10
XMSS_SHA2_16_256	SHA2-256	32	16	67	16
XMSS_SHA2_20_256	SHA2-256	32	16	67	20
XMSS_SHA2_10_512	SHA2-512	64	16	131	10
XMSS_SHA2_16_512	SHA2-512	64	16	131	16
XMSS_SHA2_20_512	SHA2-512	64	16	131	20

Description

This enum is required to pass one value to XMSS functions instead of passing all parameters for the XMSS algorithm.
