extends AsconBaseEngine
Class Inheritance
Imports
org.bouncycastle.crypto.CipherParameters, org.bouncycastle.util.Pack

Deprecated

Now superseded. Please refer to AsconAEAD128Engine for future implementations.

The AsconEngine class provides an implementation of ASCON AEAD version 1.2, based on the official specification available at: https://ascon.iaik.tugraz.at/ and the updated specification document from the NIST competition: ASCON Specification (Finalist Round) .

This version references the C reference implementation provided by NIST, available at: ASCON C Reference Implementation (NIST Round 2) .
