分布式网络环境下基于区块链的密钥管理方案

Blockchain-based key management scheme for distributed networks

为解决在分布式网络实施密钥管理困难和通信开销过大等问题,提出一种基于区块链技术的密钥管理方案(KMSBoB,key management schemes based on Blockchain)。KMSBo B中设计了分布式群组网络下基于区块链的密钥管理和传输过程,并将区块链全体成员挖矿过程和MTI/CO协议过程相结合形成动态生成会话密钥生成协议,简化了跨异构自治域下的密钥管理策略。通过仿真测试和结果分析表明KMSBoB的安全性和有效性,并且相比传统密钥管理方案通信开销更少和扩展性更高。

Regarding the difficult key management and excessive communication overhead in the distributed group networks, KMSBoB-Key management schemes based on blockchain was proposed, featuring key management and transmitting procedure based on blockchain in distributed group networks. Meanwhile, the all-member mining pro-cess of blockchain and the MTI/CO protocol process were combined to establish a protocol of dynamically generat-ed session key, so as to streamline key management strategies in cross-heterogeneous autonomous domains. Ac-cording to simulation testing and result analysis, KMSBoB is safe and effective, with less communication overhead and higher expansibility than traditional key management schemes.
