Abstract. Highly nonlinear Boolean functions occupy an important position in the design of secure block as well as stream ciphers. This paper proves two new lower bounds on the non...
The task of a fast correlation attack is to efficiently restore the initial content of a linear feedback shift register in a stream cipher using a detected correlation with the out...
In 2008 I. Dinur and A. Shamir presented a new type of algebraic attack on symmetric ciphers named cube attack. The method has been applied to reduced variants of stream ciphers T...
NLS is a stream cipher which was submitted to eSTREAM project. A linear distinguishing attack against NLS was presented by Cho and Pieprzyk, which was called as Crossword Puzzle at...
When the network is homogeneous, choosing the cipher type for a packet telephony application is simple. It is clear that stream ciphers perform better than block ciphers over land...
