Subversion-resilient enhanced privacy ID
Anonymous attestation for secure hardware platforms leverages tailored group signature schemes and assumes the hardware to be trusted. Yet, there is an ever increasing concern on the trustworthiness of hardware components and embedded systems.

MonZa: Fast maliciously secure two party computation on Z_{2^k}
In this paper we present a new 2-party protocol for secure computation over rings of the form Z2k. As many recent efficient MPC protocols supporting dishonest majority, our protocol consists of a heavier (input-independent) pre-processing phase and a very efficient online stage.

Vector commitment techniques and applications to verifiable decentralized storage
Vector commitments with subvector openings (SVC) [Lai-Malavolta and Boneh-Bunz-Fisch, CRYPTO'19] allow one to open a committed vector at a set of positions with an opening of size independent of both the vector’s length and the number of opened positions.
