Abstract: A clock frequency of a clock signal is calculated, with the clock signal being received by an IC card from a terminal or an internal clock within the IC card. A first time-stamp is received from the terminal, and a first value of the timer is set. The timer of the IC card is started when the first time-stamp is received. A second time-stamp is received, and a second value of the timer is read when the second time-stamp is received. The frequency is calculated by comparing a difference between the second and the first timer values, and a difference between the second and the first time stamps.

Abstract: A solid state memory including a processor and a method for protecting the digital contents of the solid state memory. The microprocessor inserts at least an interruption during a copying or a reading of the digital contents and proceeds with the copying or reading only subsequent to a verification of a PIN or other user action. In particular, the verification provides control to ensure that the PIN is inserted manually. Access may be prevented if a time elapsed between the interruption and inputting of a PIN is shorter than a threshold time representing a speed of manual input, or if the PIN does not correspond to a sequence of requests for access to selectable files, which may be virtual files. The interruption may comprise substituting altered or cryptographic data if verification fails, or reproduction of an audio or visual message to be understood by the user.

Abstract: 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.

Abstract: The present invention relates to a method and system for controlling a number of writing cycles supported by a cell or portion (11) of a non volatile memory (4) of an IC Card (10), including the steps of counting write accesses to the memory portion (11) and storing a first counter (21) of the write accesses in another portion (21) of said non volatile memory (4). The method comprises coupling the first counter (21) to a second counter or value (31) associated to a RAM (4) (Random Access Memory) of the IC Card (10), wherein the second counter or value (31) is updated each time the write accesses occur on said cell or portion (11) to be controlled and the first counter (21) is written in the another portion of non volatile memory only when the second counter or value (21) corresponds to a predetermined value.
