摘要：As various applications of wireless ad hoc network have been proposed, security has become one of the big research challenges and is receiving increasing attention Securing communications in resource constrained, infrastructure-less environments such as Mobile Ad Hoc Networks (MANETs) is very challenging. Cryptographic techniques are widely used for secure communications in wired and wireless networks. Most cryptographic mechanisms, such as symmetric and asymmetric cryptography, often involve the use of cryptographic keys. However, all cryptographic techniques will be ineffective if the key management is weak. The purpose of key management is to provide secure procedures for handling cryptographic keying materials. The tasks of key management include key generation, key distribution, and key maintenance. In MANETs, the computational load and complexity for key management are strongly subject to restriction by the node's available resources and the dynamic nature of network topology. A number of key management schemes have been proposed for MANETs. In this paper, we present a survey of the research work on key management in MANETs according to recent literature then we propose a zone based variant of the recently proposed cluster-based hybrid schema, with an attempt to keep the advantages of the hybrid schema.
