A Hybrid Schema Zone-Based Key Management for MANETs

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.
