We address the problem of connectivity in Secure Wireless Sensor Networks (SWSN) using random pre-distribution of keys. We propose a geometric random model for SWSNs. Under this new and realistic model, we describe how to design secure and connected networks using a small constant number of keys per sensor. Extensive simulations support the above stated result and demonstrate how connectivity can be guaranteed for a wide interval of practical network sizes and sensor communication ranges.
