CeBIT: CyphWay – One device for all scenarios

25.02.2014
Smartphones and tablets allow easy and convenient sending of images and information anywhere. But when it comes to sensitive data, security is important. Their widespread use makes tablets and smartphones a lucrative target for spies. CyphWay, developed at the Fraunhofer Institute of Optronics, System Technologies and Image Exploitation (IOSB) closes this vulnerability. The core of CyphWay is a trusted hardware module, which encapsulates and protects safety-critical components, such as encryption, decryption, and key management, and ensures optimal protection of sensitive data.

CyphWay


Ever new cases of hacker attacks, data leaks, and espionage demonstrate the lack of data security when sending and receiving between workplace and cloud, between enterprise server and tablet, or from smartphone to smartphone. In many areas this prevents police, government agencies, and companies from taking full advantage of fast, mobile data communication. A business owner, for example, may want to send sensitive contract data to their company, for which they require a line that is secured against eavesdropping. A police officer who has taken a photo of the crime scene with a cellphone is not allowed to send the image to colleagues with standard communication technology. He may do this only if unauthorized access to the data can be excluded at the highest level of security. The experts for secure communication architectures at Fraunhofer IOSB are working on a highly secure communication solution that can be used with all available devices.

CyphWay – a small add-on device – provides a maximum-security channel for data transmission. “The safety systems of CyphWay have a modular structure. This allows for easy adjustment of the safety system to different application scenarios,” explains project leader Dr. Andreas Jakoby of Fraunhofer IOSB. One module, for example, specializes in the encryption and decryption of data. Another module provides a secure connection between the add-on device and the communication hardware used. This allows CyphWay to be connected both to stationary hardware – such as a desktop PC or a server environment – and to a tablet or smartphone via a wireless connection.
The cryptographic functions of CyphWay can be used for secure provision of data on a cloud, mobile access to corporate data, or secure telephone conferences. The connection between a smartphone or other mobile device and CyphWay can be established, for example, through an encrypted Bluetooth channel. For secure sending of photos taken with a cellphone camera, the image file is first transferred to the add-on device, where it is encrypted before being sent back to the cellphone as a secured file.

 
Tampering is futile

 
“Secured with strong cryptographic systems, the file can safely be sent to another mobile device or a server. Should it fall into the wrong hands, the transmitted information cannot be read and is useless to the data thief,” explains Jakoby.
At the recipient of the protected information the file is also processed by the security module of their CyphWay device and can then be viewed and edited on screen. Because the data encryption and decryption takes place entirely on the additional device, the encryption processes cannot be bypassed. Unauthorized access to and tampering with the add-on device are not possible.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
