Query: Lattices for Physical-layer Secrecy: A Computational Perspective   In this paper, we use the hardness of quantization over general lattices as
the basis of developing a physical layer secrecy system. Assuming that the
channel state observed by the legitimate receiver and the eavesdropper are
distinct, this asymmetry is used to develop a cryptosystem that resembles the
McEliece cryptosystem, designed to be implemented at the physical layer. We
ensure that the legitimate receiver observes a specific lattice over which
decoding is known to be possible in polynomial-time. while the eavesdropper
observes a lattice over which decoding will prove to have the complexity of
lattice quantization over a general lattice
