延迟容忍网络的安全网络编码方案

当前针对污染攻击的解决方案需要公钥基础设施支持,但这对于移动Ad hoc网络而言并不可取,因此提出了无需公钥基础设施的网络编码方案。所提方案允许数据包相互验证,从而使中间节点可判断这些包是否可以未经源验证即可共同编码。分析和比较了其他签名方案,表明无需公钥的网络编码签名功能足以防止污染攻击。

Secure network coding scheme of delay tolerant networks

Current solutions for pollution attacks require a public key infrastructure support, but this is not desirable for the mobile Ad hoc networks. Therefore, this paper proposed the network coding scheme without public key infrastructure. This scheme could better prevent such pollution attack. It allowed the packets mutual verification, and thus an intermediate node could decide whether these packets could be encoded together without authenticating the source. Analysis and comparison of other signature schemes, the results show that this network coding without public key signature function is sufficient to prevent pollution attacks.
