Ctf multi-party-computation
WebMulti-party computation (MPC) or secure MPC (SMPC) is an important cryptographic security measure which enables multiple parties to assess a computation without revealing any private information or related secret data held by each party. As a result of technological advancements and the proliferation of the Internet, data security and privacy ... Webcomputation with a single server, where the client’s work is not guaranteed to be linear in the input/output size (e.g., [51]). Our contributions. In this work, we provide a suite of secure multi-party protocols for a number of set and multiset operations, which are union, intersection, di erence, symmetric di erence,
