1. A secure element configured to implement at least one first application, the secure element comprising:
a circuit, of the secure element, configured to:
record routing data, and a list and parameters of communication protocols compatible with the first application of the secure element;
verify a compatibility of a first communication protocol used by first messages intended for the first application of the secure element with the communication protocols of the list;
convert the first messages into second messages using a second communication protocol of the secure element in response to the first communication protocol not being compatible with any of the communication protocols of the list, the conversion including modification, in the second messages, of routing information of the first application of the secure element targeted by the first messages; and
direct the second messages to the first application of the secure element by using the routing data of the first application of the secure element;
wherein the secure element is configured to aggregate data of different applications to make a device with which the secure element communicates view the different applications as a single application.
