Cache Timing Analysis of eStream Finalists

A Cache Timing Analysis of HC-256

In this paper, we describe a cache-timing attack against the stream cipher HC-256, which is the strong version of eStream winner HC128. The attack is based on an abstract model of cache timing attacks that can also be used for designing stream ciphers. From the observations made in our analysis, we derive a number of design principles for hardening ciphers against cache timing attacks.

A Distinguish attack on Rabbit Stream Cipher Based on Multiple Cube Tester

Rabbit stream cipher is one of the finalists of eSTREAM project which uses 128-bit secret keys. Prior to us, the attacks on Rabbit has been all focused on the bias analysis and the best result showed the distinguishing attack with complexity 2. Our analysis in this paper, is based on chosen IV analysis on reduced N-S round of Rabbit though using multi cube tester. For this purpose we show for a...

Periods on Two Kinds of nonlinear Feedback Shift Registers with Time Varying Feedback Functions

Grain and Trivium are the hardware-oriented finalists of the eSTREAM. They are both based on nonlinear feedback shift registers. In this paper, we study their generalized classes of nonlinear feedback shift registers with time varying feedback functions, namely, Grain-like and Trivium-like structures. Some interesting results regarding their periods are obtained.
