This letter proposes a Perfect-Reconstruction (PR) encryption scheme b
ased on a PR QMF bank. Using the proposed scheme, signals can be encry
pted and reconstructed perfectly by using two Periodically Time-Varyin
g (PTV) digital filters respectively. Also we find that the proposed s
cheme has a ''good'' encryption effect and compares favorably with Fre
quency scramble in the aspects of computation complexity, PR property,
and degree of security.
