The present invention relates to a method for updating a firmware on a device, from a current version to a new version, said firmware being split into: &#x2014;a core part, &#x2014;an extended part comprising a plurality of entry points callable by the core part, said method comprising: &#x2014;inhibiting the entry points between the core part of the current version, called current core part, and the extended part of the current version, called current extended part; &#x2014;erasing the current extended part; &#x2014;downloading the core part of the new version, called new core part; &#x2014;erasing the current core part; &#x2014;downloading&#x2014;the extended part of the new version, called new extended part; &#x2014;activating the entry points between the new core part and the new extended part.

Method for updating a firmware on a low memory device

Modification of the execution of a platform-independent first method of an application within an integrated circuit card having a first non-volatile memory, a second rewritable non-volatile memory, a virtual machine and a processor unit, wherein said platform-independent first method includes a first operations sequence and a second operations sequence. Checking if there is a call within said platform-independent first method to a specific second method, having one parameter; &#x2014;if there is such a call and if said specific second method is not platform-independent, checking if there is an alternate function associated to said platform-independent first method stored in a memory of said integrated circuit card; if there is an associated alternate function: executing said alternate function to replace said first operations sequence; executing the second operations sequence of said platform-independent first method; otherwise executing by the first operations sequence and the second operations sequence of said platform-independent first method.

Method for modifying the execution of a platform-independent method of an integrated circuit card

An electronic device having one or more services made available to a host equipment with which it is connected. The device automatically adjusts the access capability to the services made available depending on the software platform available within the host equipment. The electronic device may include a platform identifier operating on data exchanged with the host equipment to identify the platform. The electronic device may be an electronic storage device providing access capability for reading/writing to memory, wherein the access capability is adapted to the host equipment. A memory may be partitioned into areas of memory dedicated to first and second types of software platforms available within the host equipment, and an area independent of the type of software platform. A memory may also be operated to list services authorized for a given platform, wherein a reference to this memory may be contained in a reserved memory.

Electronic device for providing self-adapting services depending on the platform of the host equipment with which it is connected

A secure portable electronic device for providing secure services when used in conjunction with a host computer having a central processing unit use two hardware device protocols readily supported by computer operating systems. Other systems and methods are disclosed.
