Class FrodoKEMParameters

java.lang.Object

org.bouncycastle.crypto.params.FrodoKEMParameters

All Implemented Interfaces:

CipherParameters, KEMParameters

public class FrodoKEMParameters
extends java.lang.Object
implements KEMParameters

Parameter sets for FrodoKEM as standardised in ISO/IEC 18033-2:2006/Amd 2:2026, Clause 14.

For each of the two standardised security levels (976 and 1344) there are, in both a SHAKE128 and an AES-128 matrix-generation variant:

• the salted "FrodoKEM" variant (frodokem976shake, frodokem1344shake, frodokem976aes, frodokem1344aes), which applies the Salted Fujisaki-Okamoto transform for tight multi-ciphertext security; and
• the ephemeral "eFrodoKEM" variant (efrodokem976shake, efrodokem1344shake, efrodokem976aes, efrodokem1344aes), which omits the salt and must only be used where fewer than 2^8 ciphertexts are produced per public key.
