Kaczynski's Ciphers

نویسنده

  • Jeanne Anderson
چکیده

A child prodigy and Harvard University graduate turned serial killer, Theodore Kaczynski—now better known as the Unabomber—constructed elaborate cipher systems to encrypt his thoughts and emotions. His personal journals contain enciphered details of his life, his beliefs and feelings about society, and his crimes. This article introduces the Unabomber’s cipher systems and through his use of these systems gives a brief glimpse into a fascinating mind that crossed the line between genius and madness.

Stream ciphers and the eSTREAM project

Stream ciphers are an important class of symmetric cryptographic algorithms. The eSTREAM project contributed significantly to the recent increase of activity in this field. In this paper, we present a survey of the eSTREAM project. We also review recent time/memory/data and time/memory/key trade-offs relevant for the generic attacks on stream ciphers.

A new CPA resistant software implementation for symmetric ciphers with smoothed power consumption: SIMON case study

In this paper we propose a new method for applying hiding countermeasure against CPA attacks. This method is for software implementation, based on smoothing power consumption of the device. This method is evaluated on the SIMON scheme as a case study; however, it is not relying on any specific SIMON features. Our new method includes only AND equivalent and XOR equivalent operations since every ...

A Filter Bank View of Block and Stream Ciphers

Vaidyanathan suggested the use of filter banks with coefficients in finite fields as stream ciphers. We show how to break those ciphers. A more general class of ciphers is introduced, which includes many well-known block ciphers, like DES, IDEA, etc. These ciphers are derived from filter banks over group rings.

Efficient Attacks on Homophonic Substitution Ciphers

Efficient Attacks On Homophonic Substitution Ciphers by Amrapali Dhavare Substitution ciphers are one of the earliest types of ciphers. Examples of classic substitution ciphers include the well-known simple substitution and the less well-known homophonic substitution. Although simple substitution ciphers are indeed simple both in terms of their use and attacks; the homophonic substitution ciphe...

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

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 of speech can pave the path for a successful cipher-text only attack. To that end, regularities ...
