Navigation: DEDIS :: Cothority :: Building Blocks :: Distributed Decryption
Once a Distributed Key has been setup, the aggregate public key can be used to encrypt a document. Such a document cannot be decrypted by any party alone, but needs the collaboration of a threshold of nodes to decrypt it.
The decrypt protocol in this directory asks every node to participate in the decryption of an encrypted data blob. In the current state it is very strongly tied to the evoting service and verifies that the current state of the vote allows to decrypt.
