The Number Theoretic Transform (NTT)-based key exchange protocol is a cryptographic method that allows two parties, Alice and Bob, to securely agree on a shared secret key over an insecure channel.

Abstract: To combat the Doppler shift caused by high mobility, orthogonal time frequency space (OTFS) systems have been proposed to convert the timevarying channel into a nearly time-invariant channel ...

Abstract: In order to extract robust features for radar high-resolution range profile (HRRP) recognition, a feature extraction method using circular convolution coefficients of HRRP is proposed in ...
