Lightning Talk: RISQVHT: A RISCV Microcontroller Delivering PostQuantum Secure Encryption and Hardware Trojans Alexander Hepp, Technical University of Munich Empowering electronic devices to support PostQuantum Cryptography (PQC) is a challenging task. Especially for low cost and resource constraint devices, hardware acceleration is usually required. The speaker presents RISQVHT, an enhanced RISCV device that integrates a set of powerful tightly coupled accelerators to speed up lattice and isogenybased PQC. The RISCV 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 tapeouttools and reverse engineering. The RISQVHT was implemented in ASIC technology and tapedout at t
