摘要
为了解决现有认证方式无法追踪恶意节点、集中式认证中心易受攻击的问题,基于区块链技术的去中心化、防篡改、可追溯特点,提出了一种分布式轻量化移动自组网认证方案。该方案包括对等网络建立、认证账本设计和共识机制选择,并分析讨论了智能合约的作用。在所提方案中,当给定对等节点之间最大传输时延τmax时,节点认证时间δ和网络规模Nt^all间的关系满足(Nt^all/3+1)τmax≤δ≤3(Nt^all+1)τmax.
In order to solve the problem that the existing authentication method can’t track the vulnerable of malicious nodes and depends on the centralized authentication center,based on the de-centralization,tamper-proof and traceable characteristics of blockchain technology,a distributed lightweight mobile Ad Hoc network authentication scheme was proposed.It included the establishment of peer-to-peer network,the design of certification ledger and the choice of consensus mechanism.Then the role of smart contracts was analyzed and discussed.In this scenario,when the maximum transmission delay maxτbetween a pair of peers is given,the relationship between node authentication timeδand network size Nt^all is satisfied with (Nt^all/3+1)τmax≤δ≤3(Nt^all+1)τmax.
