    New paper introducing DSPR at Asiacrypt'19. And new paper using DSPR for a tight security proof of SPHINCS+ at CCS'19. Later paper also with high speed implementation of SPHINCS+ and comparison to other schemes. Both available at

    MQDSS, NTRU (our merge of NTRU-HRSS and NTRUEncrypt), and SPHINCS+ made the 2nd round! As did many submissions that came out of . Congrats to all other submitters!

    The post-quantum crypto experiments at have begun. There are now two (hybrid) post-quantum key agreement algorithms supported in TLS 1.3 at Cloudflare's edge: - One based on lattices (NTRU-HRSS: big key, low CPU) - One based on isogenies (SIDH: small key, high CPU)

    We ( & I) broke RaCoSS, a signature submission, in three ways: implementation bugs; preimages for the RaCoSS hash function; inverting the RaCoSS problem using only the public key. Can efficiently sign any message.
