Practical Issues with TLS Client Certificate Authentication
Abstract
The most widely used secure Internet communication standard TLS (Transport Layer Security) has an optional client certificate authentication feature that in theory has significant security advantages over HTML form-based password authentication. In this paper we discuss practical security and usability issues related to TLS client certificate authentication stemming from the server-side and browser implementations. In particular, we analyze Apache's mod_ssl implementation on the server side and the most popular browsers – Mozilla Firefox, Google Chrome and Microsoft Internet Explorer on the client side. We complement our paper with a measurement study performed in Estonia where TLS client certificate authentication is widely used. We present our recommendations to improve the security and usability of TLS client certificate authentication.
