容迟网络是一种新型无线网络技术,近年来与命名数据网络有着融合发展的趋势。这里以发布/订阅多播协议为原型,构造了容迟网络环境下的命名数据网络环境,探讨了该环境下的安全和隐私问题。并进一步提出了基于群签名的数据包隐私保护验证方案,以及基于哈希链的防篡改TTL网络拥塞控制方案,来抵抗泛洪攻击等恶意行为。仿真实验表明基于TTL的网络拥塞控制安全方案可以有效地控制网络中的泛洪攻击等恶意行为,而哈希链方案可以有效防止用篡改TTL的方式来变相阻塞网络。
Tolerance network is a new type of wireless network technology, in recent years with the naming of data networks have a fusion development trend. Here publish / subscribe to the multicast protocol as a prototype, constructed a naming data network environment in a tolerant network environment, discussed the security and privacy issues in the environment. And further proposed packet privacy protection verification scheme based on group signature, and a tamper-proof TTL network congestion control scheme based on hash chain to resist malicious behavior such as flood attack. Simulation results show that the TTL-based network congestion control scheme can effectively control malicious behaviors such as flood attacks in the network, while the hash chain scheme can effectively prevent the network from being blocked in a disguised manner by tampering with the TTL.
