Study on distributed certificate authority system based on multi-provider model
LU Ming-long · Journal of Computer Applications · 2010
To improve the service ability and availability of Certificate Authority (CA) system in the Public Key Infrastructure (PKI),a distributed CA system based on the model of multi-provider was proposed,which can improve the CA's ability of survivability and fault-tolerant.On the basis of Quality of Service (QoS),an Analytical Hierarchy Process (AHP) approach with automatically modifying judgement matrix was proposed to estimate the quality of service,so that the best service could be selected quickly.The experimental results show that this strategy increases running efficiency of service request and meets the needs of user's QoS requirement.
