A Covert Data Transport Protocol
Both enterprise and national firewalls filter network connections. For data
forensics and botnet removal applications, it is important to establish the
information source. In this paper, we describe a data transport layer which
allows a client to transfer encrypted data that provides no discernible
information regarding the data source. We use a domain generation algorithm
(DGA) to encode AES encrypted data into domain names that current tools are
unable to reliably differentiate from valid domain names. The domain names are
registered using (free) dynamic DNS services. The data transmission format is
not vulnerable to Deep Packet Inspection (DPI).Comment: 8 pages, 10 figures, conferenc
