A mobile electronic device comprising an input interface that receives an authorisation challenge from a terminal; one or more processors implementing at least two modules, jointly performing a secure multiparty cryptographic process to generate an authorisation request cryptogram (ARQC); and an output interface that transmits an authorisation response comprising the ARQC to the terminal for use in authorising the mobile electronic device, wherein each of the modules performs that module's part of the secure multiparty cryptographic process based on secure data that is not shared outside that module; a first module of the at least two modules is programmed in a first programming language; a second module of the at least two modules is programmed in a second programming language; and the first programming language is different to the second programming language. |
