Hi everyone, TCP Fast Open has significant privacy problems which are not considered in RFC 7413. For example, this protocol allows a passive network observer to correlate connections established by the same client, which protocols such as TLS 1.3 and QUIC actively protect against. Furthermore, Fast Open cookies present a kernel-based tracking mechanism which is quite persistent. Amongst others, they can be used to conduct cross-browser tracking on the same operating system. For further details please refer to this article: https://arxiv.org/pdf/1905.03518.pdf I suggest, that the working group takes steps to highlight these privacy problems of RFC 7413. Regards, Erik
