Impact of DANE on Webpage Load Time

An authentication technique based on the domain name system (DNS), called DNS-based authentication of named entities (DANE), has been used to support the simple mail transfer protocol. However, DANE has not been extensively used for hypertext transfer protocol secure. This is possibly attributed to the increase in latency caused by DNS security extensions, which are essential for DANE. Unlike email services, web-service access is negatively impacted by latency which considerably affects the quality of experience for end users. This study assessed the extent to which DANE affects webpage load time. To investigate the load time, we developed DANEWebPerf, a tool—comprising a web browser, DNS cache server, and proxy that enables DANE use—to measure the webpage load time. Our experiments showed that using DANE increased the average webpage load time by at most 1190.9 ms. Therefore, DANE for the web does not significantly impact the quality of experience of end users.
