Nettet7. nov. 2024 · Signature schemes based on the MPC-in-the-head approach (MPCitH) have either been designed by taking a proof system and selecting a suitable symmetric-key primitive (Picnic, CCS16), or starting with an existing primitive such as AES and trying to find the most suitable proof system (BBQ, SAC19 or Banquet, PKC21).

Nettet27. mar. 2024 · We demonstrate the implication of our approach by applying it to the key-switching procedure. Our experiments show that the new key-switching method achieves a speedup of 1.2--2.3 or 2.1--3.3 times over the previous method, when the dimension of a base ring is $2^{15}$ or $2^{16}$, respectively. Nettet5. okt. 2024 · In this paper, we discuss the possibility to set up MPC-/HE-/ZK-friendly symmetric primitives instantiated with non-invertible weak bijective functions. With respect to one-to-one correspondence functions, any output of a weak bijective function admits at most two pre-images.
