![]() ![]() By trusting ten certificate authorities, a web browser can access almost 80% of HTTPS websites. With the recent hacks at certificate authorities, we also quantify which certificate authorities are most popular on the internet. We thus make the case that HTTPS should be enabled by default due to the low communications overhead. The overhead in using encryption is 333 milliseconds (about three roundtrip times on the internet) or 333/2,604 = 12.78%. The average download time over a HTTP connection is 2.604 seconds while the average download time over a HTTPS connection is 2.937 seconds. We quantify the communication time for HTTP and HTTPS download times for the most popular websites. However, the pushback against enabling secure web connections by default is due to increase in communication time. ![]() With revelations about mass surveillance, the use of secure web through TLS connections is needed for privacy.
