Multi-Party Computation in the Head – an Introduction

Thomas Bellebaum 30. April 2025

In 2016, the National Institute of Standards and Technology (NIST) announced a standardization process for quantum-secure cryptographic primitives. The goal was to find secure key encapsulation mechanisms (KEM) and signature schemes. One unique approach was the PICNIC signature scheme, a scheme utilizing the MPC-in-the-Head (MPCitH) paradigm. This made PICNIC an interesting approach, since its security relies on well researched block ciphers and hash functions. PICNIC was announced as an alternative candidate by NIST. A lot of follow-up schemes based on PICNIC, like BBQ, Banquet, and FEAST, were proposed using different block ciphers and variations on the original construction paradigm. In 2022, NIST announced a second call specifically for signature schemes. MPC-in-the-Head-based signature schemes became their own category, with multiple submissions in this call. This articel explains the core idea and functionality of early MPCitH based signature schemes and how we at Fraunhofer AISEC make use of the concepts.

How to build suitable datasets for successful detection of audio deepfakes

Nicolas Müller 31. March 2025

Deepfakes are a significant threat to democracy as well as private individuals and companies. They make it possible to spread disinformation, to steal intellectual property and to commit fraud, to name but a few. While robust AI detection systems offer a possible solution, their effectiveness depends largely on the quality of the underlying data, simply put: »Garbage in, garbage out.« But how do you create a dataset that is well suited to identifying the ever-evolving deepfakes and enables robust detection? And what constitutes high-quality training data?

Parsing X.509 Certificates: How Secure Are TLS Libraries?

Stefan Tatschner 26. February 2025

Digital certificates like X.509 are essential for secure internet communication by enabling authentication and data integrity. However, differences in how they are parsed by various TLS libraries can introduce security risks. A recent study by Fraunhofer AISEC analyzed six widely used X.509 parsers with real-world certificates. The findings reveal inconsistencies that could impact security-critical applications. In this article, we summarize the key results and explain why companies need to scrutinize their cryptographic libraries.

Fortifying Cryptography with Impeccable Circuits: Impeccable Keccak Explained

Ivan Gavrilan 13. January 2025

Cybersecurity threats are evolving, and cryptographic implementations face growing risks from fault injection attacks. Fraunhofer AISEC’s research introduces Impeccable Keccak, a new approach to secure SPHINCS+, a post-quantum cryptography digital signature scheme that has been standardized by NIST in 2024. By leveraging impeccable circuits and ensuring active security, this represents a new approach to fault-resilient cryptography.
