This complements the positive result of Bitansky and Brakerski [TCC’21], as they only required a classical decommitment message. Because non-interactive commitments can be based on injective one-way functions, assuming the Polynomial

Our construction satisfies the strongest known definition of non-malleability, i.e.

In that spirit, and in light of the cryptanalysis of Hopkins et al., recently Devadas et al. gave an elegant construction of . from a fully-specified and simple-to-state as

An optimized version of our construction requires fewer than 100 bit operations per party per bit-OT. For 128-bit security, this improves over the best previous protocols by 1

Finally, we investigate the relations between EOT and other cryptographic primitives..As side products, we present the first 2-round GUC-secure commitment i
