摘要
当PKI (Public Key Infrastructure)应用于移动网络时,会出现诸如CRL/OCSP (Certificate Revocation List / Online Certificate Status Protocol)不可用、预设信任锚不可用、高通信负载等问题。针对这些问题,提出了一种基于区块链的移动网络PKI框架。系统由提交节点、验证节点、查询节点组成。给出了应用场景和应用案例,表明该系统可以广泛应用于移动网络。对基于区块链的PKI系统进行了分析,并与传统方案进行了比较。说明SSL (Security Socket Layer)证书和设备证书的可信赖性与传统PKI系统相同。分析了基于区块链的PKI系统的存储需求和证书容量。由于证书具有有效期,提出了基于无效证书的优化方法。该优化提高了基于区块链的PKI证书管理系统的存储效率。
Blockchain based PKI and Certificates Management in Mobile Networks
Some issues such as CRL/OCSP (Certificate Revocation List / Online Certificate Status Protocol) unavailable, previsioned trust anchor unavailable, high communication load arise when PKI (Public Key Infrastructure) is leveraged into mobile networks. A blockchain based PKI framework in mobile network is proposed to solve these issues. The system is constituted by submission nodes, validator nodes, inquiry nodes. Scenarios and application cases are provided, and it shows the system can be widely used in mobile networks. The blockchain based PKI system is analyzed and compared to traditional solutions. It shows the trustworthy of SSL (Security Socket Layer) certificates and device certificates are the same as those in traditional PKI system. The storage requirement and certificate capacity of blockchain based PKI system is analyzed. Since certificates have expiry dates, the optimization method based on the invalid certificates is proposed. The optimization improves the storage efficiency of the blockchain based PKI certificate management system.
