The electronic component comprises: reference-obtaining means for obtaining a physical magnitude referred to as a reference magnitude, which magnitude is dynamically adjustable and representative of the expected activity of said component; comparator means suitable for comparing said reference magnitude with a magnitude of the same type representative of the real activity of said component; and detector means suitable for detecting an attack as a function of the result of said comparison.

Electronic component suitable for detecting attacks by delivering energy

A smart card reader capable of transmitting a power signal to a smart card to determine a duration WT called Waiting Time in keeping with the standard ISO 7816 and sending commands to the smart card, the reader comprising a detector for detecting a malfunctioning condition of the smart card and being configured to cut the power signal when the malfunctioning condition is fulfilled. This reader is remarkable in that the malfunctioning condition is different to reaching, by a counter configured to be incremented with the time from the sending of a command to the smart card, of a value corresponding to the duration WT elapsed from the sending of the command or reinitialization of the counter in response to the receipt of a protocol message of the smart card.

Devices for providing protection against intrusion in order to protect at least one electronic component. One example of the device includes an enclosure, surrounding the electronic component, which is proof against a specific type of radiation, and at least one piece of equipment selected from a receiver and a transmitter of radiation of that specific type, which is arranged inside the enclosure and substantially tuned to another piece of equipment that is complementary and disposed outside the enclosure. The device also includes a detection module suitable for detecting an intrusion if at least one receiver receives radiation of that specific type.

Securing a storage element for a binary datum, control register and chip card. This element () for storing a binary datum (D) inputs a signal representative of said binary datum, said storage to be carried out when an enable signal (ENA) is at a first predetermined level, supplies an output signal (Q) the state whereof represents the datum stored in said storage element (), and detects an attack aimed at said enable signal (ENA) or at a signal internal to said storage element.

A microcircuit card () includes means for detecting an attack on the card, and command means () capable of blowing a fuse () of the card when an attack is detected.

Microcircuit card protected by a fuse

This microcircuit card includes means for detecting an attack on the card, command means () capable of charging a charge pump () capable of applying a programming voltage (UP) to command a write operation into a cell () of a nonvolatile memory when an attack is detected, and a capacitor () arranged so as to be supplied with power during normal operation and to supply said charge pump () with power only when an attack is detected. The card () being characterized in that said capacitor () also supplies power to the command means () when an attack is detected.
