....n in binary notation, the ones correspond to these addition operations. In our context the subtraction of P is not more costly than the addition of P . This leads to the concept of redundant expansions (cf. 3] Now, the possible digits are corresponds to a subtraction of P , see, e.g. [4]. The representation is no longer unique, and the goal is to find a representation with as many zeros as possible, in order to have low complexity. This Canonical Sparse Form was independently discovered by many authors, and we refer to [5] for a historic account. It is sometimes called ....

....was presented by the authors and we confirm the results using grammatical specification method. The report is organized as follows. In section 2, we briefly present the binary algorithms for EC scalar multiplication. Section 3 is an overview of the speedup algorithms proposed by Morain and Olivos [24]. Section 4 discusses the DPA countermeasure proposed by Oswald and Aigner [27] and its complexity analysis. In section 5, we present Reitwiesner s canonical recoding approach and its application to EC scalar multiplication. In section 6, we discuss the DPA countermeasure proposed by Ha and Moon ....
....[4, 9, 16, 26, 30] Finding the best addition chain is impractical, but we can find near optimal ones. Some good algorithms exist, among which the binary algorithm (see Section 2) and some of its variations (see [16] and the implementation of the 2 method in [6] Morain and Olivos, in [24], have studied briefly the so called addition subtraction chains. These are defined as in (6) but with v, w l such that k i = v kw (7) They pointed out that addition subtraction chains are mainly important in EC based computations where the inverse of a point is obtained at no extra ....
