Dataset of DNS over HTTPS traffic from Chrome Browser (DNSForge, DSNSB, DOHli)

The dataset contains DoH and HTTPS traffic that was captured in controlled environment and generated automatically by Chrome browser with enabled DoH towards 3 different DoH servers (DNSForge, DSNSB, DOHli) and a web page loads towards a sample of web pages taken from Majestic Million dataset. The data are provided in the form of PCAP files. However, we also provided TLS enriched flow data that are generated with opensource ipfixprobe flow exporter. Other than TLS related information is not relevant since the dataset comprises only encrypted TLS traffic. The TLS enriched flow data are provided in the form of CSV files with the following columns:




Column Name
Column Description




DST_IP
Destination IP address


SRC_IP
Source IP address


BYTES
The number of transmitted bytes from Source to Destination


BYTES_REV
The number of transmitted bytes from Destination to Source


TIME_FIRST
Timestamp of the first packet in the flow in format YYYY-MM-DDTHH-MM-SS


TIME_LAST
Timestamp of the last packet in the flow in format YYYY-MM-DDTHH-MM-SS


PACKETS
The number of packets transmitted from Source to Destination


PACKETS_REV
The number of packets transmitted from Destination to Source


DST_PORT
Destination port


SRC_PORT
Source port


PROTOCOL
The number of transport protocol


TCP_FLAGS
Logic OR across all TCP flags in the packets transmitted from Source to Destination


TCP_FLAGS_REV
Logic OR across all TCP flags in the packets transmitted from Destination to Source


TLS_ALPN
The Value of Application Protocol Negotiation Extension sent from Server


TLS_JA3
The JA3 fingerprint


TLS_SNI
The value of Server Name Indication Extension sent by Client




The DoH resolvers in the dataset can be identified by IP addresses written in doh_resolver_ip.csv file.

The main part of the dataset is located in DoH-Gen-C-DDD.tar.gz and has the following structure:

.
└─── data                   | - Main directory with data
     └── generated          | - Directory with generated captures
         ├── pcap           | - Generated PCAPs
