LSST: From Science Drivers to Reference Design and Anticipated Data Products

David Atienza Alonso, Jonathan Andrew Blazek, Darong Huang, Shahram Khazaei

We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). The LSST design is driven by four main science themes: probing dark energy and dark matter, taking an inventory of the solar system, ex ...

Neutrality-Based Symmetric Cryptanalysis

Shahram Khazaei

Cryptographic primitives are the basic components of any cryptographic tool. Block ciphers, stream ciphers and hash functions are the fundamental primitives of symmetric cryptography. In symmetric cryptography, the communicating parties perform essentially ...

New Directions in Cryptanalysis of Self-Synchronizing Stream Ciphers

Shahram Khazaei

In cryptology we commonly face the problem of finding an unknown key K from the output of an easily computable keyed function F(C, K) where the attacker has the power to choose the public variable C. In this work we focus on self-synchronizing stream ciphe ...

On Reconstruction of RC4 Keys from Internal States

Shahram Khazaei

In this work key recovery algorithms from the known internal states of RC4 are investigated. In particular, we propose a bit-by-bit approach to recover the key by starting from LSB's of the key bytes and ending with their MSB's. ...
