NTRU (Number theory research unit) is a public key cryptosystem that uses lattice-based cryptography. It is more resistant to assaults than other commonly used public-key cryptosystems, and its performance has been proven to be much better. This study introduces TRUHIB, a commutative variation of the NTRU, as a novel multidimensional public-key cryptosystem. It operates using a novel mathematical structure that consists of two public keys and five private keys. in a algebra called HSS algebra. This new structure has improved the security and sophistication of the public key cryptosystem.
