METHOD, SERVER AND SYSTEM FOR SECURING AN ACCESS TO DATA MANAGED BY AT LEAST ONE VIRTUAL PAYLOAD

A first server launches, under control of a device user, an execution of a first virtual payload by using a predetermined service provider interface or a first predetermined application programming interface that is associated with the first virtual payload executed by the first server. The first virtual payload generates a first random nonce. The first virtual payload launches an execution of a second virtual payload by using an associated second predetermined application programming interface. The second virtual payload is executed by the first or a second server. The first virtual payload exchanges with the second virtual payload the first random nonce, so as to establish a first secure channel. The invention also relates to corresponding first server and system.
