Stashes the workers in the master's state and publishes
its public parameters to each one. That bundle is public: it is the
setup broadcast a coordinator would send over the wire, and it is
all a site needs in order to encrypt. After this call,
master_aggregate() can drive an iteration of the protocol.
Arguments
- master
a CKKSMaster, or the frozen legacy PaillierMaster.
- workers
a list of worker Sites.
Details
Use this for the realistic master/worker (star) topology that
distcomp- and DataSHIELD-style federated analyses follow. For the
legacy Paillier round-robin idiom, use round_robin_chain() instead.
A ThresholdMaster does not use this function: its joint public
key does not exist until key generation has run through every site,
so make_threshold_master() takes the sites and returns a master
already wired to them, in the order the chain fixed.
