Non-malleable extractor is an important tool for studying the problem of privacy amplification in classical and quantum cryptography with an active adversary.The randomness of the weakly-random source X before privacy amplification always depends on the information adversary has,called side information.We study properties of such extractors in the presence of classical and quantum side information,and show that any non-malleable extractor is essentially secure in the case where the adversary has classical side information.We also prove that non-malleable extractors are quantum-proof with uniform seed,or only require the seed to be weakly random.
