Extracting a uniform random bit-string over Jacobian of Hyperelliptic curves of Genus 2 [article]

Bernadette Faye
2017 arXiv   pre-print
By using the Mumford's representation of a reduced divisor D of the Jacobian J(F_q) of a hyperelliptic curve H of genus 2 with odd characteristic, we extract a perfectly random bit string of the sum of  ...  By this new approach, we reduce in an elementary way the upper bound of the statistical distance of the deterministic randomness extractors defined over F_q where q=p^n, for some positive integer n≥ 1  ...  Ciss for useful comments and suggestions on an earlier draft of this paper.  ...

Extractors for Jacobian of Hyperelliptic Curves of Genus 2 in Odd Characteristic [chapter]

Reza Rezaeian Farashahi
Cryptography and Coding  
We propose two simple and efficient deterministic extractors for J(Fq), the Jacobian of a genus 2 hyperelliptic curve H defined over Fq, for some odd q.  ...  Thanks to the Kummer surface K, that is associated to the Jacobian of H over Fq, we propose the sum and product extractors, SEK and PEK, for K(Fq).  ...  The author thanks to the anonymous referees for several useful suggestions.  ...
