Cryptanalysis of the Legendre PRF and Generalizations

open access: yesIACR Transactions on Symmetric Cryptology, 2020
The Legendre PRF relies on the conjectured pseudorandomness properties of the Legendre symbol with a hidden shift. Originally proposed as a PRG by Damgård at CRYPTO 1988, it was recently suggested as an efficient PRF for multiparty computation purposes by Grassi et al. at CCS 2016.
