The efficiency of representing the number by ternary expansion is discussed in the paper.
Some numbers have better efficiency in binary expansion, and some are better in ternary expansion. Then, it is believed that double-base number system (DBNS) [4], [5] can improve the efficiency of the scalar multiplication.
