Title:
Cryptanalysis on a novel unconditionally secure oblivious polynomial evaluation protocol

Authors: Wang Qinglong, Xu Li

Abstract:

Vanishree et.al proposed a novel unconditionally oblivious polynomial evaluation protocol and they claimed that can fulfill both sender and receiver’s security. Here, this protocol is cryptanalyzed. We find that it has a fatal fault which cannot implement the receiver’s security at all and show the detail analyzing process.
