Excited to share two new threshold encryption schemes.

More details here:

1. Silent Threshold Encryption (CRYPTO 2024 - ): The first scheme to completely avoid interactive setup without using iO/WE.hackmd.io/@guruvamsi-pol…
ia.cr/2024/263 Parties sample their public-key pair *independently* but need a KZG CRS. To encrypt, you just need to download the committee's public keys + threshold can be chosen at the time of encryption. Also gives us timelock encryption with a silent setup.

Concretely efficient!
