Class LongPolynomial5
java.lang.Object
org.bouncycastle.pqc.math.ntru.polynomial.LongPolynomial5
public class LongPolynomial5
- extends java.lang.Object
A polynomial class that combines five coefficients into one long
value for
faster multiplication by a ternary polynomial.
Coefficients can be between 0 and 2047 and are stored in bits 0..11, 12..23, ..., 48..59 of a long
number.

LongPolynomial5
public LongPolynomial5(IntegerPolynomial p)
- Constructs a
LongPolynomial5
from a IntegerPolynomial
. The two polynomials are independent of each other.
- Parameters:
p
- the original polynomial. Coefficients must be between 0 and 2047.
mult
public LongPolynomial5 mult(TernaryPolynomial poly2)
- Multiplies the polynomial with a
TernaryPolynomial
, taking the indices mod N and the values mod 2048.
