Abstract

A method for executing applications on an untrusted device includes selecting one or more applications as sensitive applications. One or more instruction sequences of the said one or more sensitive applications are modified by an external dongle. The one or more sensitive applications are executed on the untrusted device according to the modified instruction sequences. Whether correct execution of the instructions of the said modified instruction sequences has occurred is checked by the external dongle.
