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.

Efficient computation of polynomial multiplication over characteristic three fields is required for post-quantum cryptographic applications which gain importance upon the recent advances in quantum computers. In this paper, we propose three new polynomial multiplication algorithms over F-3 and show that they are more efficient than the current state-of-

Will You Cross the Threshold for Me?
In this work, we propose generic and novel side-channel assisted chosenciphertext attacks on NTRU-based key encapsulation mechanisms (KEMs). These KEMs are IND-CCA secure, that is, they are secure in the chosen-ciphertext model.

Modified Multi-Key Fully Homomorphic Encryption Based on NTRU Cryptosystem Without Key-Switching
The Multi-Key Fully Homomorphic Encryption (MKFHE) based on the NTRU cryptosystem is an important alternative to the post-quantum cryptography due to its simple scheme form, high efficiency, and fewer ciphertexts and keys.

Modern cryptographic transformations of the end-to-end encryption type, namely – NTRU-like cryptosystems are considered. A new cryptographic system NTRU PRIME IIT UKRAINE was created based on existing cryptographic transformations of this type. A brief description of this cryptosystem is presented and an analysis of its resistance to known attacks is ...
