Class NTRUPlusConcurrencyTest

java.lang.Object

junit.framework.Assert

junit.framework.TestCase

org.bouncycastle.pqc.crypto.test.NTRUPlusConcurrencyTest

All Implemented Interfaces:

junit.framework.Test

public class NTRUPlusConcurrencyTest
extends junit.framework.TestCase

An NTRUPlusKEMExtractor holds one NTRUPlusEngine for its lifetime, so the engine must not carry mutable state across a call. It used to keep a single SHAKE instance in a field: two threads extracting through one extractor interleaved their absorb/squeeze phases, which produced wrong shared secrets and threw IllegalStateException: attempt to absorb with odd length queue. The digest is now built per call, as CMCEEngine's already was.

The generator side is exercised too, since NTRUPlusKEMGenerator builds an engine per call but its KEM keys and parameters are shared - and NTRUPlusParameters hands every engine the same zetas array, so a write to it would corrupt globally.
