Dynamic ad hoc networks (DANETs) are similar to mobile ad hoc networks (MANETs), but the network density and mobility change significantly over time and space. Many researchers have proposed types of key management schemes for ad hoc networks. In this chapter, we provide a timely survey of the existing solutions and describe the state-of-the-art techniques for DANETs security key management, where we particularly consider those more suitable for DANET. Following a brief discussion on the limitations and challenges of key management in DANET, we introduce the main and desirable features and evaluation metrics of key management. Then a categorization of existing key management systems is presented. Finally, we conclude this chapter with a summary of further developments.
