This Bachelor Thesis focuses on the capabilities to transfer large amount (e.g. 200 MB) of
DICOM image on smartphones and tablets across a public network such as Internet.
This investigation takes into account the Austrian legal aspects for medical data transfer,
which requires the newest sophisticated cryptographic methodologies for ensuring secure
and optimal data transfer.
The main challenge is to establish a possible encrypted consultation with a medical expert
through a mobile device. With regard to the latest technology achievements, can we really
obtain an accurate expert opinion by sending a simple DICOM example file of coronary
circulation, which requires an in-depth medical examination?
Therefore, the objectives of this work are (i) to define the minimal required bandwidth
while sending encrypted large files through the network and (ii) to assess the impact of the
encryption methods on the transfer speed (i.e. bit rate).
The preliminary results obtained during this study highlight that two algorithms can be
used in Austria for medical image encryption. These are Advanced Encryption Standard
(AES) and Triple Data Encryption Standard (3DES).
Several studies demonstrate that AES is faster and uses less energy than 3DES and
therefore could be used in an effective way for this specific purpose. Transfer of large
DICOM file could be possible with new mobile communication technology standard 4G
LTE that is available in Austria and with short range Wi-Fi.
However, it should be point-out that the theoretical calculation can differ significantly from
the reality, and therefore the transmission using the AES or 3DES, as well as Wi-Fi and
the newest 4G technology, should be further tested and validated.
