Abstract. Even and Mansour [EM97] proposed a block cipher construction that takes a publicly computable random permutation oracle P and XORs different keys prior to and after appl...
In this paper we present a new class of stream ciphers based on a very simple mechanism. The heart of our method is a Feedback with Carry Shift Registers (FCSR) automaton. This au...
Deliberate injection of faults into cryptographic devices is an effective cryptanalysis technique against symmetric and asymmetric encryption. We will describe a general concurren...
In this paper, we describe a sequence of simple, yet efficient chosen-plaintext (or chosen-ciphertext) attacks against reduced-round versions of IDEA (with 2, 2.5, 3, 3.5, and 4 ro...
This paper describes an adaptive-chosen-ciphertext attack on the Cipher Feedback (CFB) mode of encryption as used in OpenPGP. In most circumstances it will allow an attacker to det...
