Accelerating Regularized Iterative CT Reconstruction on Commodity Graphics Hardware (GPU)
Iterative reconstruction algorithms augmented with regularization can produce high-quality reconstructions from few views and even in the presence of significant noise. In this pa...

A Modified Hill Cipher Involving Interweaving and Iteration
This paper deals with a modification of the Hill cipher. In this, we have introduced interweaving in each step of the iteration. The interweaving of the resulting plaintext, at ea...

Modified HSS iteration methods for a class of complex symmetric linear systems
In this paper, we introduce and analyze a modification of the Hermitian and skewHermitian splitting iteration method for solving a broad class of complex symmetric linear systems....

Attacking Power Generators Using Unravelled Linearization: When Do We Output Too Much?
We look at iterated power generators si = se i−1 mod N for a random seed s0 ∈ ZN that in each iteration output a certain amount of bits. We show that heuristically an output of...
