arkworks-threshold-decryption

Pairing-based threshold decryption library

DO NOT USE IN PRODUCTION, VERY MUCH IN PROGRESS

This repository implements a threshold decryption scheme based on BZ03. We implement two further optimizations to this scheme:

• One allows for 'additional data' to be augmented to the ciphertext, essentially achieving a threshold-decryptable AEAD scheme.
• The second allows for batching the decryption shares together, and to have the end-verifier only need to verify the combined decryption share.
