Enhanced Performance and Privacy via Resolver-Less DNS
Erik Sy
The domain name resolution into IP addresses can significantly delay connection establishments on the web. Moreover, the common use of recursive DNS resolvers presents a privacy ri…
Accelerating QUIC's Connection Establishment on High-Latency Access Networks
Erik Sy, Tobias Mueller, Moritz Moennich +1
A significant amount of connection establishments on the web require a prior domain name resolution by the client. Especially on high-latency access networks, these DNS lookups cau…
QUICker connection establishment with out-of-band validation tokens
Erik Sy, Christian Burkert, Tobias Mueller +2
QUIC is a secure transport protocol that improves the performance of HTTPS. An initial QUIC handshake that enforces a strict validation of the client's source address requires two…
Enhanced Performance and Privacy for TLS over TCP Fast Open
Erik Sy, Tobias Mueller, Christian Burkert +2
Small TCP flows make up the majority of web flows. For them, the TCP three-way handshake induces significant delay overhead. The TCP Fast Open (TFO) protocol can significantly decr…
Surfing the Web quicker than QUIC via a shared Address Validation
Erik Sy
QUIC is a performance-optimized secure transport protocol and a building block of the upcoming HTTP/3 standard. To protect against denial-of-service attacks, QUIC servers need to v…
Enhanced Performance for the encrypted Web through TLS Resumption across Hostnames
Erik Sy, Moritz Moennich, Tobias Mueller +2
TLS can resume previous connections via abbreviated resumption handshakes that significantly decrease the delay and save expensive cryptographic operations. For that, cryptographic…
