Other Electrical Engineering, Electronic Engineering, Information Engineering IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2021 KeywordsField programmable gate arrays, Entropy, Generators, Training, Side-channel attacks, Deep learning, Power measurement, TRNG, side-channel attack, power analysis, FPGA, bitstream modification The combined attack opens a new attack vector which makes possible what is not achievable with pure bitstream modification or side-channel analysis. We demonstrate the attack on the example of an open source AIS-20/31 compliant ring oscillator-based TRNG implemented in Xilinx Artix-7 28nm FPGAs. In this brief, we show that an attack combining power analysis with bitstream modification is capable of classifying the output bits of a TRNG implemented in FPGAs from a single power measurement. A compromised TRNG may lead to a system-wide loss of security. True Random Number Generators (TRNGs) create a hardware-based, non-deterministic noise that is used for generating keys, initialization vectors, and nonces in a variety of applications requiring cryptographic protection. 1710-1714 Article in journal (Refereed) Published Abstract Continued abuse of our services will cause your IP address to be blocked indefinitely.2021 (English) In: IEEE Transactions on Circuits and Systems - II - Express Briefs, ISSN 1549-7747, E-ISSN 1558-3791, Vol. Please fill out the CAPTCHA below and then click the button to indicate that you agree to these terms.

There is no official GameFAQs app, and we do not support nor have any contact with the makers of these unofficial apps. Continued use of these apps may cause your IP to be blocked indefinitely. This triggers our anti-spambot measures, which are designed to stop automated systems from flooding the site with traffic.

Some unofficial phone apps appear to be using GameFAQs as a back-end, but they do not behave like a real web browser does.Using GameFAQs regularly with these browsers can cause temporary and even permanent IP blocks due to these additional requests. If you are using Maxthon or Brave as a browser, or have installed the Ghostery add-on, you should know that these programs send extra traffic to our servers for every page on the site that you browse.The most common causes of this issue are: Your IP address has been temporarily blocked due to a large number of HTTP requests.
