Cipher text only attack on speech time scrambling systems using correction of audio spectrogram

H. Ghasemzadeh; M. Tajik Khasss; H. Mehrara

Volume 9, Issue 2 , July 2017, , Pages 131-145

Abstract
  Recently permutation multimedia ciphers were broken in a chosen-plaintext scenario. That attack models a very resourceful adversary which may not always be the case. To show insecurity of these ciphers, we present a cipher-text only attack on speech permutation ciphers. We show inherent redundancies ...  Read More

Toward an energy efficient PKC-based key management system for wireless sensor networks

Abstract
  Due to wireless nature and hostile environment, providing of security is a critical and vital task in wireless sensor networks (WSNs). It is known that key management is an integral part of a secure network. Unfortunately, in most of the previous methods, security is compromised in favor of reducing ...  Read More
