An efficient binary sequence generator with cryptographic applications

As the Internet has become more and more important, the need for secure systems has increased accordingly. Our proposal is an efficient sequence generator that can be used in these secure systems. It is based on the powers of a block upper triangular matrix and, besides achieving great statistical results and efficiency, it is very flexible and can be easily adapted to different applications. The matricial techniques employed can also be used in other kinds of cryptographic primitives.
