This PDF document describes the Helix stream cipher, devised by Niels Ferguson, Doug Whiting, Bruce
Schneier, John Kelsey, Stefan Lucks, and Tadayoshi Kohno. The cipher produces a MAC for every
plaintext it encrypts. Source code is not included in this document, but Qualcomm Australia has
implemented Helix in C.

Hiji Bij Bij
Describes the Hiji Bij Bij stream cipher devised by Palash Sarkar and the Cryptology Research Group
at the India Statistical Institute. Like many new stream ciphers, it has two parts to its state,
one part updated linearly and one part updated non-linearly. The linear part is implemented as
cellular automata. The cipher can run in a self-synchronizing mode. The C source code is in this
postscript document.
