Source code of the prototype presented in the paper A Trusted Message Bus Built on Top of D-Bus, presented at 20th Brazilian Symposium on Information and Computational Systems Security (SBSeg 2020).
A wide range of applications use Inter-Process Communication (IPC) mechanisms to communicate between each other or between their components running in different processes. A well-known IPC mechanism in UNIX-like systems is D-Bus, which allows processes to communicate by receiving and routing messages. Despite being widely used, such system lacks mechanisms to provide end-to-end data confidentiality. In this paper we propose the use of Intel Software Guard Extensions (SGX) to provide a trusted communication channel between local applications over the D-Bus message bus system. We obtained stronger security guarantees in message confidentiality and integrity while keeping a small Trusted Computing Base (TCB) and compatibility with the reference D-Bus system.

The system require D-Bus Daemon 1.12.2 and SGX SDK 2.9.101.2.
After the requirements being install, for the server just run:
./test_server <trusted>
And, for the client:
./run_test.sh <trusted> <messages> <repeats> <datatype>
Where <trusted>
is 0
or 1
. The <messages>
is the amount of messages you are going to send. The <repeats>
is the number of tests that will run, and <datatype>
is the type of data to be sent: 1 = 1 byte
; 2 = 2 bytes
; 3 = 4 bytes
; 4 = 8 bytes
; 5 = string;
and 6 = array
.
