Hash functions from superspecial genus-2 curves using Richelot isogenies

In 2018 Takashima proposed a version of Charles, Goren and Lauter’s hash function using Richelot isogenies, starting from a genus-2 curve that allows for all subsequent arithmetic to be performed over a quadratic finite field 𝔽p2. In 2019 Flynn and Ti pointed out that Takashima’s hash function is in...
