Cryptanalysis of a computer cryptography scheme based on a filter bank
arXiv:0710.5471 · doi:10.1016/j.chaos.2008.01.020
Abstract
This paper analyzes the security of a recently-proposed signal encryption scheme based on a filter bank. A very critical weakness of this new signal encryption procedure is exploited in order to successfully recover the associated secret key.
