Abstract: An electronic device such as a hardware security module device comprises a first cryptographic processing circuit configured to receive input data packets and apply thereto a first cryptographic processing to provide output data packets. A second cryptographic processing circuit is provided in the device, configured to receive the output data packets, apply thereto a second cryptographic processing inverse to the first cryptographic processing, and provide comparison data packets as a result of applying the second cryptographic processing to the output data packets received. A comparison processing circuit in the device is configured to compare the input data packets with the comparison data packets, and to produce an error signal as a result of the input data packets being different from the comparison data packets.

Abstract: A method for rendering an edge of a graphics primitive to be displayed on a screen. Such edge has an inclination relative to a reference direction of the screen. The method includes the steps of: calculating, based on the inclination of the edge, an error coefficient representative of the distance of the edge from a center of a pixel of the screen; and associating a transparency coefficient to the pixel, based on the calculated error coefficient.

Abstract: In order to estimate power consumption, over a given time interval, of digital circuits described at the level of functional elements provided with input/output terminals associated additional elements are emulated at the hardware level. The said additional emulated elements are able to detect, during said time interval, at least one signal indicative of the behavior of the functional element associated during hardware emulation of the circuit. Preferably the number of transitions performed during the aforesaid time interval of the associated functional element is recorded, as well as the fraction of time in which the state of said functional element is stable. The value of said signals is acquired to perform an estimation of the power consumption of the functional element during the aforesaid time interval.
