I'm not sure how that could be the case. Dan was among the first to push the notion of post-quantum cryptography, along with Johannes Buchmann and his research group at Darmstadt (which credit him in [1] with the coining of the notion of "post-quantum cryptography"). Both organized the first PQCrypto conference in 2006, and edited the first book on post-quantum crypto. [1] https://eprint.iacr.org/2004/297 https://eprint.iacr.org/2004/297
