+## Libntru Notes
+
+Libntru use some custom data types declared in `types.h`. 
+
+`NtruIntPoly` : Polynomial with 16-bit integer coefficients
+
+```c
+    typedef struct NtruIntPoly {
+        uint16_t N;
+        int16_t coeffs[NTRU_INT_POLY_SIZE];
+    } NtruIntPoly;
+```
+
+`NtruTernPoly` : Ternary polynomial, all coefficients are equal to -1, 0, or 1.
+```c
+    typedef struct NtruTernPoly {
+        uint16_t N;
+        uint16_t num_ones;
+        uint16_t num_neg_ones;
+        uint16_t ones[NTRU_MAX_ONES];
+        uint16_t neg_ones[NTRU_MAX_ONES];
+    } NtruTernPoly;
+```
