摘要

摘要: 移动自组织网络资源有限，且节点之间共享无线信道并以协作的方式完成消息转发，导致所传输消息的机密性较为脆弱。为保护消息内容的机密性，该文提出一种间断连接移动自组织网络中的消息转发机制。各节点对原始消息进行切割，并利用多副本消息转发过程的冗余性和节点相似性控制各片段消息在不相交的路径上进行转发，进而由网络中的摆渡节点收集、检验并还原、加密得到仅目的节点能够解密的完整消息，确保转发过程中消息的机密性、完整性。数值分析表明所提机制在保障网络性能前提下，能有效保护消息的机密性。

Abstract: 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.
