[ TLS 1.3 Handshake Data Collected By Lumen (CCR 2020) ]
Data Format
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:
proxied
denotes whether the connection was proxied by Lumen.flow_time
time flow started.app_package
the application package responsible for the flow.app_version
the version of the application responsible for the flow.sni
the Server Name Indication (SNI) for this connection.dst_ip
the destination IP address for the flow.dst_port
destination port.client-hello-version
the TLS version announced by the Client Hello in the outer record.client-supported-versions
the supported versions extension contents in the Client Hello.client-ciphers
the list of cipher suites supported by the client.client-extensions
the list of extensions present in the Client Hello.curves
the list of elliptic curves supported by the client.point_formats
the list of elliptic curve point formats supported by the client.client-supported-psk
the list of pre-shared key modes supported by the client.server-version
the 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-cipher
the cipher suite picked by the server.server-extensions
the list of extensions in the Server Hello.server-downgrade-marker
whether the server set the TLS 1.3 downgrade marker.server-hello-retry-request
whether the server sent a Hello Retry Request to the client.
