3118 针对软件定义网络（SDN）中数据包缺乏有效转发验证机制的问题，提出了一种基于属性签名标识的数 据包转发验证方案。 Aiming at the lack of effective forwarding verification mechanism for packet in software defined network (SDN), a data packet forwarding verification scheme based on attributed-based signatures identification was proposed.
3119 首先，根据用户的身份属性生成属性签名标识，并为数据包打上属性签名标识。 First, the attribute signature identification was generated according to the user's identity attribute, and the data packet was marked by the attribute signature identification.

The controller verified the attribute signature of the sampled data packet. The OpenFlow forwarding device processes the abnormal data packets according to the flow table issued by the controller.
3121 最后，构建了多控制器架构，避免了控制器单点失效故障。 Finally, a mul- ti-controllers architecture was constructed to avoid the single point failure of the controller.
3122 实验 结果表明，所提方案实现了对数据包的精确控制与采样，能有效检测数据包篡改、伪造等异常行为，其网络时延 处于可行通信时延范围内。 The results of the experiment indicate that the scheme can achieve accurate control and sampling of data packet, effectively detect the forwarding ab- normal behaviors such as packet tampering and forgery, and the network delay is within the range of feasible communi- cation delay.
