Class FrodoKEMConcurrencyTest

java.lang.Object
  junit.framework.Assert
      junit.framework.TestCase
          org.bouncycastle.pqc.crypto.test.FrodoKEMConcurrencyTest

All Implemented Interfaces:

junit.framework.Test

public class FrodoKEMConcurrencyTest

extends junit.framework.TestCase

A FrodoKEMExtractor holds one FrodoKEMEngine 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 . The digest is now built per call, as CMCEEngine's already was.

The generator side is exercised too, since FrodoKEMGenerator builds an engine per call but its KEM keys and parameters are shared.
