Several ideal-lattice-based cryptosystems have been broken by recent attacks that exploit special structures of the rings used in those cryptosystems. The same structures are also used in the leading proposals for post-quantum lattice-based cryptography, including the classic NTRU cryptosystem and typical Ring-LWE-based cryptosystems.
In this talk I will speak about NTRU Prime, which tweaks NTRU to use rings without these structures. I will talk about more motivation for using this new system, discuss it's security by looking at attacks and if time allows, speak about Streamlined NTRU Prime, which optimizes NTRU Prime from an implementation perspective.
