Multicasting style of communication in ad-hoc networks are becoming an effective tool for many applications. These applications require security goals such as authenticating the source and integrity of message. Due to dynamic nature of ad-hoc network and unguaranteed connectivity make these inappropriate. A new approach two-tiered authentication scheme for multicast traffic for large scale ad-hoc networks has been proposed. This approach uses the time asymmetry, secret information asymmetry and Message authentication code to provide security over networks. This approach uses central authority for key management in ad-hoc networks. This approach will provide security and reliability over the network.
