In this paper we focus on the development of a pseudo-random number generator (PRNG) to be used as a key generator for a symmetrical encryption system in a one-time-pad like environment, particularly useful for WSN. Our PRNG is based on the Lorenz chaotic system through a new approach of applicability of chaotic systems to cryptography, that we named 'modular-chaos'. We evaluate our proposal using both analytical and experimental techniques that lead us to an efficient and robust solution against statistical attacks and present strong random properties. Our approach solves the problem of short-cycle length of discrete chaotic systems.
