资源公钥基础设施RPKI:现状与问题

Resource public key infrastructure RPKI:status and problems

BGP(border gateway protocol,边界网关协议)在设计之初并没有充分考虑安全问题,随着互联网规模的日益壮大,其安全风险也暴露得愈加明显。学术界和工业界提出了诸多方案解决域间路由面临的安全问题,目前真正得以部署的是IETF(the Internet Engineering Task Force,互联网工程任务组)推动的资源公钥基础设施(resource public key infrastructure,RPKI)。综述了RPKI的技术现状和研究进展,重点分析了RPKI存在的问题、现有的解决方案以及不足之处,介绍了RPKI功能扩展的相关研究,最后指出了未来有潜力的研究方向。

The BGP(border gateway protocol)did not fully consider security issues at the beginning of its design.With the rapid growth of the Internet,its security risks have become incrementally obvious.Academia and industry have proposed many solutions to the security issues faced by inter-domain routing,and what is really deployed is the RPKI(resource public key infrastructure)promoted by the IETF(the Internet Engineering Task Force).The development status and research advances of RPKI were surveyed,with emphasis on problems of RPKI,existing solutions,and related limitations.Moreover,latest achievements on RPKI function extension were introduced.Finally,future research directions were concluded.
