Improved Ring LWR-Based Key Encapsulation Mechanism Using Cyclotomic Trinomials
2020
IEEE Access
In the field of post-quantum cryptography, lattice-based cryptography has received the most noticeable attention. Most lattice-based cryptographic schemes are constructed based on the polynomial ring R q = Z q [x]/f (x), using a cyclotomic polynomial f (x). Until now, the most preferred cyclotomic polynomials have been x n + 1, where n is a power of two, and x n + · · · + x + 1, where n + 1 is a prime. The former results in the smallest decryption error size, but the choice of degree is
