GCComputation

This is a high level stereotype for secure multi-party computation with garbled circuits. We expect that two of these tasks (executed by different parties) are grouped together to mark joint secure computation.

The inputs and outputs of this task are the inputs that the party has for the secure computation and the parties get a joint output.

Required input parameters

group (with GCComputation tasks)

Optional input parameters

input script

Restrictions

Restriction: “groupId” property must exist under stereotype details object - group must have been selected and saved and “groupId” information must not have been deleted from model’s file
Error: groupId is undefined

Restriction: “inputScript” property must exist under stereotype details object - “inputScript” can be empty, but must not have been deleted from model’s file
Error: inputScript is undefined

Group specific restrictions

Restriction: stereotype group must have at least one input and one output data object
Error: group must have at least 1 input and 1 output object

Restriction: there must be exactly two tasks in the same stereotype group
Error: group must have exactly 2 members

Restriction: all group tasks from the same stereotype group must be on different lanes
Error: each group task must be on separate lane

Restriction: any task from the stereotype group must not be in the incoming or outgoing path of another task from the same stereotype group
Error: all group tasks must be parallel

Restriction: all tasks from different stereotype groups must be in the same order on each lane - ordered lists of stereotype groups must match for each lane
Warning: all group tasks are possibly not parallel

Restriction: all tasks from the same stereotype group that have common Exclusive Gateway elements in their paths (all tasks have the same exclusive gateway in their paths) must exist in all paths that start from these common exclusive gateways
Warning: group task is possibly not accessible to the rest of the group

Restriction: there must be at least one Start Event element on the model (to run parallelism checks)
Warning: Start Event element is missing
