NTRU+ is a lattice-based key encapsulation mechanism (KEM) based on the NTRU framework and designed to provide IND-CCA2 security. The document summarizes the scheme structure and parameter sets, and discusses implementation and protocol considerations including key-generation rejection sampling, input validation, pairwise consistency testing, explicit rejection behavior, randomness requirements, and side-channel leakage during decapsulation. It is intended to help protocol designers and implementers use NTRU+ safely in settings such as authenticated key exchange, public key encryption, and KEM-based authentication.
