A method for the personalization of an integrated circuit card, includes: simulating a downloading of a single image corresponding to a fixed part of personalization data of the integrated circuit card; simulating an execution of a sequence of personalization commands for the integrated circuit card to generate a set of personalization data; combining the set of personalization data with the single image to obtain a card image comprising the fixed part of personalization data and the set of personalization data; encrypting the card image to obtain an encrypted single image; and downloading the encrypted single image in a memory of the integrated circuit card.

A method for managing storage of an operating system in an integrated circuit card, includes: subdividing an operating system into a plurality of operating system components; associating one or more operating system components of the plurality of operating system components to a descriptor indicating a version of the one or more operating system components; downloading the one or more operating system components to a memory of the integrated circuit card, wherein the downloading includes verifying if an operating system component stored in the integrated circuit card is a same version of the one or more operating system components being downloaded; based on the verifying, storing the one or more operating system components in the card if the version is different; and based on the verifying discarding the one or more operating system components from the download operation if the version is the same.

A method for controlling a loss of reliability of a non-volatile memory (NVM) included in an integrated circuit card (ICC) may include determining whether the NVM is reliable at the operating system (OS) side of the ICC, and generating an event associated with the reliability of the NVM at the OS side for an application of the ICC, if the NVM is determined to be unreliable.

Method and system for controlling loss of reliability of non-volatile memory

A virtual machine or hardware processor for an IC-card portable electronic device includes a non-volatile memory unit, a remote decryption unit, and associated objects for storing an executable program in an encrypted format in the non-volatile memory. The IC-card stores a licence key to encrypt and decrypt the executable program through an IC-card interface. The IC-card interface extracts and encrypts the operands of the plain executable program into encrypted operands so as to not limit performance. The remote decryption unit detects if an instruction contains encrypted operands, and queries a decryption to the IC-card interface. The IC-card interface decrypts the encrypted operands and re-encrypts the just decrypted operands into obscured operands through a dynamic obscuration key.

Virtual machine or hardware processor for IC-card portable electronic devices

An IC Card may include electronic components to receive a power supply and a main clock signal by a reader device. The power supply may be provided to a subset of the electronic components during a main clock stop status wherein the main clock signal is suspended for avoiding a maximum power consumption threshold. The IC Card may also include a low precision clock included in the subset of electronic components for measuring time in the main clock stop status.
