ePrint Report: Key-Recovery Attack on a Public-Key Encryption Related to Planted Clique

Caicai Chen, Chris Jones

Hudoba proposed a public key encryption (PKE) scheme and conjectured its security to be based on the Planted Clique problem. In this note, we show that this scheme is not secure. We do so by devising an efficient algorithm for the even neighbor independent set problem proposed by Hudoba. This leaves open the possibility of building PKE based on Planted Clique.
