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.
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 provides data encryption and decryption
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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
