1. Computing device with user interface comprising a physical processing means, said physical processing means including:
- a first virtual machinea second virtual machine;
wherein an execution space is defined in each virtual machine;
wherein the execution spaces of the first and second virtual machines host applications;
wherein the applications hosted in the execution space of the second virtual machine have a higher level of security than that of the applications hosted in the execution space of the first virtual machine;
wherein the applications of the execution space of the first virtual machines are user-modifiable applications;
wherein the applications of the execution space of the second virtual machines are user-unmodifiable applications;
wherein the two virtual machines are separable only by destruction of the physical processing means; and
wherein the first and second virtual machines are distinct and each of the first and second virtual machines is associated with a single corresponding execution profile.

Abstract
The invention relates to a user interface-equipped computing device comprising means for implementing a series of applications, said means including two execution spaces. According to the invention, the applications of the second execution space (100, P1, 200, P2) have a level of security specifically higher than that of the applications of the first execution space (100, P1, 200, P2), said two execution spaces being hosted by a physical processing means which is designed such that it cannot be separated into two parts without destroying the physical processing means.
