TWOPRIME: a fast stream ciphering algorithm. In this paper, we describe an additive stream ciphering algorithm, called ”TWOPRIME”. It is designed for 32-bit computers, and the key has 128 bits. It is fast in software and analytical in the sense that some security aspects of the algorithm can be controlled. A faster version of TWOPRIME is also presented. We also describe a variant of TWOPRIME, called ONEPRIME, which is for 64-bit machines.
