The fast exponentiation is a crucial one in any kind of public key cryptosystem. Lim-Lee proposed a method for an efficient exponentiation in elliptic curve by dividing n-bit scalar into equal length of simple scalars. In this paper, the general Lim-Lee method is further improved by using the signed binary window method and direct doublings.
