[ TLS 1.3 Handshake Data Collected By Lumen (CCR 2020) ]
The data file
ccr_tls_release.csv.xz contains handshake records and extension information from the TLS connections from the Lumen dataset up to early November 2019.
Each row contains information about the flow itself including destination IP address and port, the application associated with the flow like app package name and version, and the TLS handshake such as relevant information from the TLS Client Hello and Server Hello messages.
The code that was used to produce the stats and figures in our CCR 2020 paper can be found on our GitHub repository. The rows in this file are as follows:
proxieddenotes whether the connection was proxied by Lumen.
flow_timetime flow started.
app_packagethe application package responsible for the flow.
app_versionthe version of the application responsible for the flow.
snithe Server Name Indication (SNI) for this connection.
dst_ipthe destination IP address for the flow.
client-hello-versionthe TLS version announced by the Client Hello in the outer record.
client-supported-versionsthe supported versions extension contents in the Client Hello.
client-ciphersthe list of cipher suites supported by the client.
client-extensionsthe list of extensions present in the Client Hello.
curvesthe list of elliptic curves supported by the client.
point_formatsthe list of elliptic curve point formats supported by the client.
client-supported-pskthe list of pre-shared key modes supported by the client.
server-versionthe TLS version announced by the Server Hello in the outer record.
resulting-version(=max server_version,supported_version)the version negotiated in the connection.
server-cipherthe cipher suite picked by the server.
server-extensionsthe list of extensions in the Server Hello.
server-downgrade-markerwhether the server set the TLS 1.3 downgrade marker.
server-hello-retry-requestwhether the server sent a Hello Retry Request to the client.
