摘要：
In the resource-constrained intermittent connectivity Ad-hoc networks, the wireless media is shared by collaborated nodes for message forwarding, and the confidentiality of messages is particularly vulnerable. To protect the confidentiality of the message content, a message forwarding mechanism for intermittent connectivity Ad-hoc networks is proposed. In this mechanism, the original message is sliced into several pieces to conceal the confidentiality, then taking advantage of the redundancy of message forwarding process from multi-copy routing and the node similarity, the forwarding paths of each piece are controlled to be disjoined. Consequently, the ferry nodes collect these pieces, verify their reliability, and restore to the original message, then encrypt it where only the destination node can decrypt the ciphertext. Finally, the confidentiality and integrity of messages in the forwarding process can be achieved. Numerical analysis shows that under the premise of network performance guaranty, the proposed mechanism can effectively protect the confidentiality of the message. ©, 2015, Science Press.
