N2 - A quantum circuit providing an undetectable eavesdropping of information encoded by bit flip operations in Ping-Pong protocol has been recently proposed by Pavičić [Phys. Rev. A, vol. 87, pp. 042326, 2013]. A modification of the protocol's control mode is proposed. The introduced improvement remedies deficiencies of the protocol seminal version and permits Pavičić's attack detection with overwhelming probability. The improved version is also immune to famous Wójcik's attack [Phys. Rev. Lett., vol. 90, pp. 157901, 2003]. As a result, the Ping-Pong protocol asymptotic security is restored both in perfect and lossy quantum channels.
