Robust and private computations of mobile agent alliances

ly spoken, error behaviour is one aspect of the adversary behaviour as errors can be assigned to the adversary. It defines the way an adversary influences a protocol, the methods it can use. A categorisation is done by [HH91], where crash failures, sending omission, receiving omission, general omission failures, and, finally, arbitrary failures are differentiated. In case errors occur arbitrarily, the literature speaks of Byzantine errors (see for example [PBG89, CR93]. The SMAC model in chapter 5 uses a Byzantine error model as most of today’s cryptographic protocols do.
