Abstract
Abstract: InMobile ad hoc networks (MANETs) security has become a primary requirements. Thecharacteristics capabilities of MANETsexposeboth challenges and opportunities in achieving key security goals,such as confidentiality,access control,authentication, availability, integrity, and non-repudiation.Cryptographic techniques are widely used for secure communications in both TCP and UDPnetworks. Most cryptographic mechanisms, such as symmetric and asymmetric cryptography,often involve the use of cryptographic keys. However, all cryptographic techniques will beunsecure or inefficient if the key management is weak. Key management is also a central component inMANET security. The main purpose of key management is to provide secure methods for handlingcryptographic keying algorithm. The tasks of key management includes keys for generation, distribution and maintenance. Key maintenance includes the procedures for key storage, keyupdate, key revocation, etc. In MANETs, the computational load and complexityfor key management are strongly subject to restriction by the node’s available resources and thedynamic nature of network topology. A number of key management schemes have beenproposed for MANETs. In this article, we present a survey of the research work on keymanagement in MANETs according to recent publications.
