Lightning Talk: RISQV-HT: A RISC-V Microcontroller Delivering Post-Quantum Secure Encryption - and Hardware Trojans - Alexander Hepp, Technical University of Munich Empowering electronic devices to support Post-Quantum Cryptography (PQC) is a challenging task. Especially for low cost and resource constraint devices, hardware acceleration is usually required. The speaker presents RISQV-HT, an enhanced RISC-V device that integrates a set of powerful tightly coupled accelerators to speed up lattice and isogeny-based PQC. The RISC-V ISA is extended with 41 new instructions and performs roughly 10 times faster than a software solution when encrypting with Kyber and 21 times faster when encrypting with SIKE. As a twist, four hardware Trojans were inserted into the final chip, threatening the security properties of integrity, confidentiality and availability. The speaker shows how to detect such Trojans with tape-out-tools and reverse engineering. The RISQV-HT was implemented in ASIC technology and taped-out at t
