Line 8: ==Security== The security of a two-party computation protocol is usually defined through a comparison with an idealised scenario that is secure by definition. The idealised scenario involves a [[Trusted_third_party\|trusted party]] that collects the input of the two parties over [[secure ~~channels~~channel]]s and returns the result if non of the parties chooses to abort. The cryptographic two-party computation protocol is secure, if it behaves no worse than this ideal protocol, but without the additional [[trust]] [[assumption]]s. This is usually modeled using a simulator. ==References==
