»Chaos« bei den Daten im Cache verbessert die Sicherheit

Ein Team aus Bochumer Wissenschaftlern hat in Kooperation mit Forschern aus Japan eine innovative Verschlüsselung designt, die nicht nur eine größere Sicherheit bietet als die bisherigen Ansätze, sondern auch effizienter und schneller ist.

Code Kept Secret for Years Reveals Its Flaw—a Backdoor

A secret encryption cipher baked into radio systems used by critical infrastructure workers, police, and others around the world is finally seeing sunlight. Researchers say it isn’t pretty.

Enhancing Security Through Randomized Data

A team of scientists from Bochum, Germany, in cooperation with researchers from Japan, has now developed an innovative cipher that not only offers greater security than previous approaches, but is also more efficient and faster.

Das Dilemma der IT-Sicherheitsbeauftragten

Beauftragte für IT-Sicherheit in Unternehmen haben es schwer: Sie verlangen dem Personal zusätzlichen Aufwand ab und müssen dem Management in Zahlen belegen, dass sie erfolgreich sind. Dabei sind sie wenig in Unternehmensstrukturen eingebunden und auf eingekaufte Werkzeuge angewiesen, die nur wenig zum sicheren Verhalten der Mitarbeitenden beitragen.

How randomized data can improve our security – Tech Xplore

Modern processors use a cache to act as a bridge between the two, since memory is much slower at providing data than the processor is at processing it. This cache often contains private data that could be an attractive target for attackers.

A cifra SCARF define novos padrões na proteção de dados confidenciais

Um grupo de pesquisadores internacionais alcançou um avanço na segurança de computadores ao desenvolver uma nova e eficiente cifra para randomização de cache.

Satelliten-Sicherheit hinkt Stand der Technik Jahrzehnte hinterher

Mittlerweile befinden sich im Orbit um die Erde Tausende von Satelliten, und es werden noch viel mehr werden. Wie es aus IT-Perspektive um die Sicherheit dieser Systeme bestellt ist, haben Forschende der Ruhr-Universität Bochum und vom CISPA Helmholtz-Zentrum für Informationssicherheit in Saarbrücken untersucht.

How Hackers Can Hijack a Satellite

A computer flying hundreds or even thousands of kilometers in the sky, at a speed of tens of thousands of kilometers an hour, is nonetheless still a computer. And every connected computer has an attack surface.

Wie Hacker einen Satelliten kapern können

Ein Computer, der mit einer Geschwindigkeit von Zehntausenden Kilometern pro Stunde Hunderte oder sogar Tausende Kilometer am Himmel fliegt, ist dennoch ein Computer. Und jeder angeschlossene Computer verfügt über eine Angriffsfläche.

Satellite Technology Advances but Satellite Security Lags Behind

There are currently thousands of satellites orbiting the Earth, and these numbers are only going to grow. The technology of these satellites is quickly improving, but are they protected enough?

Satellite security lags decades behind the state of the art

Thousands of satellites are currently orbiting the Earth, and there will be many more in the future. Researchers from Ruhr University Bochum and the CISPA Helmholtz Center for Information Security in Saarbrücken have assessed the security of these systems from an IT perspective.

Wenn Forscher in Sprechblasen reden

Ob Atomkraft oder Klimawandel - die Szene der Comiczeichner hat diese Themen für sich entdeckt. Gerade trifft sie sich zum Münchner Comicfestival. Auch Forscher nutzen das Medium, um ihre Inhalte zu erklären.

New and Secure Encryption: A Fresh Approach

Cryptography, i.e. the encryption of information, keeps us safe in our daily lives and yet we barely know it’s there. As digitalization progresses, the amount of data that needs to be protected is growing exponentially. This calls for exceptionally robust cryptographic solutions that are both fast and efficient in practice and, at the same time, absolutely secure.
