Cryptanalysis of a Video Scrambling Based on Space Filling Curves
In this paper, we study the security of an image scrambling algorithm based on Space-Filling Curves (SFC). A random SFC is a pixel permutation that changes the scanning order with...

Identity-Based Hierarchical Strongly Key-Insulated Encryption and Its Application
In this paper, we discuss non-interactive updating of decryption keys in identity-based encryption (IBE). IBE is a public key cryptosystem where a public key is an arbitrary strin...

Fast (Parallel) Dense Linear System Solvers in C-XSC Using Error Free Transformations and BLAS
Existing selfverifying solvers for dense linear (interval-)systems in C-XSC provide high accuracy, but are rather slow. A new set of solvers is presented, which are a lot faster th...
