Disclosed are a key generation method, apparatus, an electronic device, and a storage medium. The key generation method comprises: obtaining a channel characteristic parameter of a wireless channel; generating a key according to the channel characteristic parameter; capturing after continuously generating multiple keys, a first key matrix by means of a sliding window having a preset length, to obtain a second key matrix; determining a correlation between keys in the second key matrix, and performing key substitution on the keys in the second key matrix when the correlation between the keys in the second key matrix is greater than a preset threshold; and adding the keys in the second key matrix to a key pool until the number of keys in the key pool reaches a preset number.

Key generation method, apparatus, electronic device and storage medium

A method for determining a transmission channel in a millimeter wave system, a signal transmission method, an apparatus for determining a transmission channel in a millimeter wave system, a signal transmission apparatus, a millimeter wave system, a computer device, and a computer readable medium, the method includes: constructing a beam spatial channel model of a millimeter wave system, wherein the beam spatial channel model uses a matrix with sparsity to represent sub-beams in the millimeter wave system, and elements in the matrix represent channel gains of respective sub-beams in the millimeter wave system, respectively; acquiring a beam spatial channel matrix of a legitimate user in the beam spatial channel model; and using a sub-beam with concentrated energy in the beam spatial channel matrix of the legitimate user as a transmission channel.
