TLS middlebox
- An internet connection
Ability to detect the presence of TLS middleboxes censoring requests based on the servername.
-
control_sni
(string
): a SNI to use as control (e.g.example.org
) -
testhelper
(endpoint
): a URL liketlshandshake://<host>:<port>
orhttps://<host>:<port>
-
sni
(string
; optional): a potentially blocked SNI to measure (e.g.1337x.be
)
The default implementation will use a domain such as example.org
as
the control_sni
and the testhelper's hostname as the target.
This test is divided into multiple steps that will each ensure that we can successfully
perform iterative tracing on the target
and return early in case of failure.
The main steps of the experiment are:
-
DNS lookup Perform a A/AAAA query to the configured DoH resolver for the testhelper's hostname. Fall back to the system resolver in case DoH fails and record the lst of DNS responses/records under the "queried" key (see df-002-dnst.md).
-
TCP Connect Attempt to establish a TCP session on port 443 (default, overriden by the port in the testhelper) for the list of IPs identified at step 1. The results of the connecting end up in the "tcp_connect" key. (see df-005-tcpconnect.md).
-
TLS Handshake Attempt to perform a tls handshake for the list of filtered IPs (for which the TCP session can successfully established) obtained at step 2. The handshake is performed iteratively for each IP with an increment in the TTL for each successive iteration.
The entire tracing is done twice: using the
control_sni
and thetarget
. Each iteration records the handshake results along with the corresponding TTL. The results of the trace end up in thetrace
key which is divided into two:control_trace
(the trace for thecontrol_sni
) andtarget_trace
(the trace for thetarget_sni
). Eachtrace
field records the iterations for a single servername till we receive anull
failure (a successful handshake) or aconnection_reset
. The handshake results are recorded in thehandshake
field. (see df-006-tlshandshake.md)
We will include data following these data formats:
df-002-dnst
df-005-tcpconnect
df-006-tlshandshake
{
"queries": [],
"tcp_connect": [],
"iterative_trace": {
"address": "",
"control_trace": {},
"target_trace": {}
}
}
where:
-
queries
contains a list ofdf-002-dnst
instances -
tcp_connect
contains a list ofdf-005-tcpconnect
instances -
iterative_trace
contains the SNI-based iterative trace of the form:
{
"ttl": ,
"handshake": {}
}
where:
-
ttl
is a positive integer -
handshake
follows thedf-006-tlshandshake
data format
-
If there is a middlebox attempting to censor content in the network route
-
If the blocking of a particular servername is due to the presence of a middlebox in the network route.
