This research proposes a pre-signed response method based on online certificate status protocol (OCSP) request prediction. A request prediction method is proposed to analyse and predict potential volumes of certificate signing requests for a given time or period, so that responses to the requests can be generated and pre-signed during off-peak hours for load balancing. In our experiment, the OCSP request data in a certificate centre is collected and analysed for the evaluation of our proposed method. Our results show that the accuracy rate of our proposed method is about 96.17% in the prediction of traffic volumes.
