Designing integrated accelerator for stream ciphers with structural similarities

HiPAcc-LTE: An Integrated High Performance Accelerator for 3GPP LTE Stream Ciphers

Stream ciphers SNOW 3G and ZUC are the major players in the domain of next generation mobile security as both of them have been included in the security portfolio of 3GPP LTE-Advanced, the potential candidate for 4G mobile broadband communication standard. In this paper, we propose HiPAcc-LTE, a high performance integrated design that combines the two ciphers in hardware, based on their structu...

Designing Self-Synchronizing Stream Ciphers with Flat Dynamical Systems

In this paper, we present properties of dynamical systems and their use for cryptographical applications. In particular, we study the relationship with the self-synchronizing stream ciphers from a structural point of view. A special class of dynamical systems, namely the piecewise linear systems, are then considered. I. I The main objective of the paper is to show how dynamical syste...

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.
