This task is used to reconstruct additively secret shared data. It takes additive secret shares of the same value as an input and outputs the value.

2…n data objects (additive shares) from AddSSSharing task / AddSSComputation or FunSSComputation task groups

1 data object (secret data)

Restriction: task must have at least two input and exactly one output data objects
Error: at least 2 inputs and exactly 1 output are required

Restriction: all input data objects must be outputs of AddSSSharing task / AddSSComputation or FunSSComputation task groups and they must be all from the same stereotype group
Error: all input function shares must originate from the same task with AddSSSharing stereotype or from the same group of tasks with AddSSComputation or FunSSComputation stereotypes

Restriction: all names of input data objects must be different
Error: all input function shares must be different
