Abstract: In hyperelliptic curve cryptosystems, it is one of the main steps in computing scalar multiplication to evaluate 2D+E from the given elements D and E in the Jacobian of a hyperelliptic curve. In this paper, an optimized method for computing 2D+E is proposed, which will raise the computing efficiency by about 6%~8%.
Key words: hyperelliptic curve cyrptography, Jacobian, addition algorithm, Harley algorithm
