In general, the invention relates to a method for executing at least a portion of a server operation. The method includes providing an extension to a client connected to the server, where the extension includes a portable object connected to the client. The method further includes performing at least the portion of server operation by the extension, where performing at least the portion of the server operation includes executing a copy of at least a portion of server software stored on the portable object.

Method and system using a portable object for providing an extension to a server

The method to check module chaining in a modular software architecture located in an electronic unit with microprocessor comprising, apart from the microprocessor, a memory space, uses an identification, secured by the hardware, of the calling module. The invention also concerns an electronic unit with microprocessor designed to implement the above method.

Method and system for module chaining control in a modular software architecture

A method and device to control the access to a data memory space of a computer system by an active process stored in a program space of the system. When the active process attempts to perform an operation on a part of the data memory space the method or device controls the access to the part of the data memory space by comparing a dynamic attribute linked to the active process to an attribute linked to the part of the data memory space the process is attempting access. The value of the dynamic attribute is updated according to the present and previous status of the active process.

Access control method and device in an embedded system

The invention relates to a method for activating one (A) of the applications (A-A) of an on-board or embedded system, particularly of a chip card () connected to a terminal () equipped with a reader, by means of a 'web' browser. The terminal () and the chip card () each comprise, in addition to the conventional protocol layers () corresponding to the ISO 7816 standards, a specific layer (). The latter comprises intelligent agents () for establishing two-way data exchange sessions, enabling the chip card () to offer a 'web' server functionality. In addition, the chip card () comprises intelligent agents (ATS-ATS) called script translators that interact with the applications (A-A), making it possible to activate a selected application (A) using conventional commands corresponding to the ISO 7816 standards. In a variant of embodiment, provisions are made for a dynamic updating of the chip card (), particularly from the browser. The invention also relates to the corresponding on-board system.

On board system comprising network interface means, and method for activating applications located in said on-board system

The present invention relates to a smart integrated circuit. This smart integrated circuit is characterized in that it has a main processor () and an operating system executing a main program (P) for constituting a main task-performing process, at least one secondary processor () capable of concurrently executing at least one secondary program (P) for constituting at least one task-performing process, power supply circuits () common to the processors and means for ensuring that the secondary processor or processors with similar power and different operating signatures are executed concurrently with the main process by continuously or intermittently inducing, in the power supply circuits, power disturbances that are superimposed on those of the main process so as to produce a continuous or intermittent scrambling.
