#source-code for a new #post-quantum #crypto implementation: an embedded-optimized ARM assembly implementation of NewHope key exchange, an algorithm using the NTT (Number-Theoretical Transform), with #performance of under 2M clock cycles on the Cortex-M0. By Erdem Alkim, Philipp Jakubeit, and Peter Schwabe.
on 02016-08-03“SPHINCS-256 is a high-security #post-quantum stateless hash-based signature scheme that signs hundreds of messages per second on a modern 4-core 3.5GHz Intel CPU. Signatures are 41 KB, public keys are 1 KB, and private keys are 1 KB. SPHINCS-256 is designed to provide long-term 2128 security even against attackers equipped with quantum computers.” #djb #crypto #algorithms
