"the only thing the simulator can do in the ideal model is to choose the corrupted parties' inputs." Yehuda Lindell said.
1- what will happen when the corrupted parties have no inputs to the protocol? e.g. in cases that the corrupted party/parties are just some computing servers with no input.
2- in these cases, is it any relationship between security against malicious and semi-honest adversaries. As I am thinking that, as the corrupted party has no input, anything that a malicious adversary is able to do is also possible for the semi-honest adversary.
is it possible in any way to conclude security against malicious adversaries in these cases when we have proved security against semi-honest adversaries?
