An Efficient Random Number Generator for Ad hoc Sensor Network
Network of wireless micro-sensor for monitoring physical environments has emerged as an important new application area for wireless technology. The strength of security protocols and encryption algorithms for ad hoc sensor network has been focused. Random numbers play a crucial role in them, so the quality of random number becomes one of important indexes. Because key attributes of these new types of network system are the severely constrained computation and energy resources, and an ad hoc operational environment, the design of random number generator must consider them. This paper presents new and security random number generator architecture for this type network. The philosophy architecture is based on single electron circuit which ensures the unpredictability of the produced random numbers. The proposed architecture is a flexible solution taking into account the performance, power consumption, flexibility, cost and area.
