摘要：A primary concern in Mobile Ad Hoc Networks (MANETs) is security. Secret sharing is an effective way to distribute a secret among n parties, where each party holds one piece of the secret. A number of key management schemes have been proposed for MANETs. However the secret sharing to control key hierarchy needs larger message transmission costs in many techniques. Existing research in key management can only handle very limited number of nodes and are inefficient, insecure, or unreliable when the nodes increases. Here this study modifies Autonomous key management scheme is proposed to address both for security and efficiency for key management in Mobile Ad hoc Network (MANET). It also reduces communication and computational cost in Ad-Hoc Network and works for large number of nodes.
