We consider key generation protocol published recently by D.Qin and Z.Ding and called by them EVSKey scheme. This protocol is based on extraction by legitimate users of eigenvalues, which are invariant by matrix commutation and it does not require reciprocal channels connecting the users. We extend this protocol to extraction of matrix traces and we consider quantization procedure in more detail. On the contrary, to a statement of D.Qin and Z.Ding we prove that their sharing protocol occurs insecure for any distances between eavesdropper and legitimate users. In order to provide reliability and security of the shared key we propose to add artificial noises in channels and to use error correction codes and privacy amplification methods.
