Abstract
The invention relates to a secure portable object of the smart card type comprising (a) an object body and (b) a micro-module comprising a processor and at least one memory in which a first application executed by a first execution engine in a first execution space is stored. The invention is characterised in that a second application is further stored in the said at least one memory, where the said second application is executed by a second execution engine distinct from the first execution engine, in a second execution space distinct from the first execution space. The invention particularly applies to smart cards.
Claims18
A secure portable object of the smart card type comprising (a) an object body and (b) a micro-module comprising a processor and one or more memories in which a first and a second application are stored, a first and second execution engine capable of executing the said first and second application, and in that the said first application is executed by the said first execution engine in a first execution space and the said second application is executed by the said second execution engine in a second execution space distinct from the first execution space.
A portable object according to any of foregoing claims, wherein an execution space extends to a specific resource and in that another execution space does not extend to the said specific resource.
A method for securing a secure portable object of the smart card type comprising (a) an object body and (b) a micro-module comprising a processor and one or more memories in which a first and a second application are stored, further comprising the following stages, where:
- a first and a second execution engine capable of executing the said first and second applications are provided;
- the first execution engine executes the first application in a first execution space;
- and
- second execution engine executes the second application in a second execution space distinct from the first execution space.
