On the Privacy of a Code-based Single-server Computational Pir Scheme
We show that the single-server computational PIR protocol proposed by Holzbaur, Hol- lanti and Wachter-Zeh in [HHW20] is not private, in the sense that the server can recover in polynomial time the index of the desired file with very high probability. The attack relies on the following observation. Removing rows…
