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.

@@@@Delay-Tolerant Network (DTN) is a novel type of wireless network technique, and now has a trend in mergence with NDN (Named-Data Networks). With publication/subscription multicast protocol as the primitive model, a NDN environment under DTN is constructed, a deep discussion on the security and privacy issues under this environment is don. And then a privacy protected package validation scheme based on group signature is proposed, including the tamper-resistant TTL congestion control scheme based on hash chain. The simulations show that the TTL congestion control scheme could effectively protect the network from malicious behaviors such as flooding attack, while the hash chain effectively prevent the malicious user in tampering the TTL and blocking the network in disguised form.
