“…Hardware security aims at understanding security breaches in ICs and developing mechanisms for detecting attacks or preventing them by implementing countermeasures for on-chip resilience. Hardware security has been studied extensively for digital ICs recently [1]- [5], but for analog, mixed-signal, and RF ICs, only a few methodologies have been proposed; the solution space is still largely unexplored [6], [7].…”

In this paper, we demonstrate a recently proposed security technique for mixed-signal circuits in the context of a real application. The security technique, called MixLock, is based on logic locking of the digital section of the mixed-signal circuit and can be used as a countermeasure for reverse engineering and counterfeiting. We demonstrate MixLock in an audio application, where the underlying Σ∆ ADC that digitizes the audio input is locked. We show the effect that locking has on the recorded audio quality based on a metric that counts the resultant glitches per second and by also providing a link where the interested reader can download and listen to output audio samples for locked and unlocked versions of the Σ∆ ADC.

“…We define the BIST module as the central intelligence unit (CIU) in the hardware security terminology. Many research works were done for security checking and protection provision in the digital domain [11,12], while only a few studies are seen in the analog/mixed-signal domain [15][16][17][18][19][20][21]. Due to this lack of knowledge, more research needs to be done in the area of analog/mixed-signal hardware security in order to find and develop related threats and countermeasures.…”

Mixed-signal integrated circuits (ICs) play an eminent and critical role in design and development of the embedded systems leveraged within smart weapons and military systems. These ICs can be a golden target for adversaries to compromise in order to function maliciously. In this work, we study the security aspects of a tunnel field effect transistor (TFET)-based first-order one-bit delta-sigma (∆Σ) analog to digital converter (ADC) through proposing four attack and one defense models. The first attack manipulates the input signal to the ∆Σ modulator. The second attack manipulates the analog version of the modulator output bit and is triggered by the noise signal. The third attack manipulates the modulator output bit and has a controllable trigger mechanism. The fourth attack manipulates the analog version of the modulator output bit and is triggered by a victim capacitance within the chip. For the defense, a number of signal processing filters are used in order to purge the analog version of the modulator output bit for elimination of the malicious unwanted features, introduced by the attacks. According to the simulation results, the second threat model displays the strongest attack. Derived from the countermeasure evaluation, the best filter to confront the threat models is the robust regression using the least absolute residual computing method.
