Quantum Computing

Quantum computing not only brings great opportunities, but also new risks for cyber security. As quantum computers could be able to solve highly complex problems exponentially faster than conventional computers, there will be risks to confidential data in the future. Attackers could use a quantum computer to break through encryption or carry out new types of cyberattacks that overwhelm traditional security systems. At the same time, quantum algorithms can contribute to improving cyber security, for example through more complex random number generators, new encryption techniques or the identification of security problems.

Fraunhofer AISEC is researching the secure use of quantum computers and the use of quantum computing to increase cyber security.

Anomaly Detection with Quantum Machine Learning – Identifying Cybersecurity Issues in Datasets

Since the release of ChatGPT, the popularity of Machine Learning (ML) has grown immensely. Besides Natural Language Processing (NLP) anomaly detection is an important branch of data analysis whose goal is to identify observations or events that deviate from the rest of the data. At Fraunhofer AISEC, cybersecurity experts explore Quantum Machine Learning methods for anomaly detection. One approach is based on the classification of quantum matter while a second method uses a type of Quantum Support Vector Machine with a kernel that is calculated on a quantum computer. This blog post explains the fundamentals of anomaly detection and shows the two approaches being pursued by the Quantum Security Technologies group at Fraunhofer AISEC.
