      We describe an improved algorithm for computing a multiple of a point
      on elliptic curves defined  over finite fields of characteristic greater 
      than three. The proposed algorithm is based on new formulae for computing 
      repeated doubling points with only one field inversion, and the signed-digit
      exponent recoding algorithm. The new algorithm is shown to be faster than 
      Müller's 1997 method. Our new formulae  for repeated doubling points 
      can also be used to speed up algorithms such as the $k$-ary method and
      the signed binary  window method.
