Cluster Based Node Misbehaviour Detection, Isolation and Authentication Using Threshold Cryptography in Mobile Ad Hoc Networks
In mobile ad hoc networks, the misbehaving nodes can cause dysfunction in the network resulting in damage of other nodes. In order to establish secure communication with the group members of a network, use of a shared group key for confidentiality and authentication is required. Distributing the shares of secret group key to the group members securely is another challenging task in MANET. In this paper, the authors propose a Cluster Based Misbehavior Detection and Authentication scheme using threshold cryptography in MANET. For secure data transmission, when any node requests a certificate from a Cluster Head (CH), it utilizes a threshold cryptographic technique to issue the certificate to the requested node for authentication.
