Neuromorphic networks for signal and information processing have acquired recently a renewed interest considering the more and more complex tasks that have to be solved automatically in current applications: speech recognition, dynamic image correlation, rapid decision processing integrating a plurality of information sources, behavior optimization, etc… Several types of neuromorphic networks do exist and, among […] >>

The most innovative communication systems for beyond 5G and future 6G applications have to face a number of challenges related to the trade-offs between link range, power consumption and data-rate. A growing interest is put on radio frequency circuits operating at mmW and sub-THz bands because at those frequencies there are large portions of available […] >>

Since 2018 and the announcement of the Spectre and Meltdow vulnerabilities, the hard-won performance gains of desktop and server processors over the past few decades have been called into question. These vulnerabilities effectively exploit the speculative and out of order execution found in all modern processors to gain in the number of instructions performed per […] >>

Work carried out within the CEA-Leti has shown that physical attacks can be a threat to the security mechanisms of SoCs (System-On-Chips). Indeed, fault injections by electromagnetic disturbance have already led to an elevation of privileges by authenticating with an illegitimate password, or more recently have made it possible to circumvent one of the highest […] >>

CESTI is an Information Technology Security Evaluation Facility (ITSEF) laboratory dedicated to security evaluations of integrated circuits. During its evaluation process, various tests can be performed, amongst whose perturbation attacks. The latter consists in modifying chip behavior in order to get secret keys, to bypass authentication steps or to get rid of specific countermeasures. Laser, […] >>
