....processor architectures. Several authors have presented explicit formulas for performing the group law in the jacobian. These formulas are speci c to the genus 2 or genus 3 cases and improve upon Cantor s algorithm and its derivatives. A historical survey of the contributions can be found in [60]. Two recent contributions are those of Lange [47] and Pelzl et al. 60] For genus 2 curves, Lange presented addition formulas that take 1 inversion, 22 multiplications, and 3 squarings in the underlying eld, and doubling formulas that require 2 additional squarings. For genus 3 curves, Pelzl et ....

....Picard curves) Still, it is most important to compute eciently in the group, and an important part of today s reseach is devoted to allowing fast arithmetic in Jacobians of curves. For instance, many papers study the case of hyperelliptic curves of genus 2 and 3 ( Lan02] MCT01] KGM 02] PWGP03] In this article, we nd explicit formulae for computing in the Jacobian of a Picard curve, basing us on some geometric aspects of these curves. Volcheck ( Vol94] Huang and Ierardi ( HI94] have already proposed general methods for computing in the Jacobians of arbitrary algebraic curves. ....

For more details on previous improvements made to the explicit formulae the interested reader is referred to [PWGP03] For genus 3 hyperelliptic curves of odd characteristic the only improvement over Cantor s algorithm was presented in [KGM 02] The authors adopted the methods from [MDM 02,Har00] to obtain the speed up. The operation complexity for genus 3 curves is summarized in Table 3. Theoretical ....

....HECC Cantor [Can87] presented algorithms to perform the group operations on HEC in 1987. In recent years, there has been extensive research being performed to speed up the group operations on genus two HECC [Nag00,Har00,MCT01,MDM 02,Tak02,Lan02a,Lan02b,Lan02c] and genus three [Nag00,KGM 02,PWGP03] Only Nagao [Nag00] tried to improve Cantor s algorithm for higher genera. He mainly applied the following ideas: Division of polynomials without eld inversion Computation of the gcd with one inversion. Interleaving super uous calculations in the reduction part Expressing points on ....

The table entries are sorted in chronological order. All implementations use Cantor s algorithm with polynomial arithmetic. We remark that the contribution at hand is the rst genus 4 HECC implementation ....
