Title: 2-Phase Adiabatic Logic For Low-Energy and CPA-Resistant Implantable Medical Devices
Designing a low-energy and secure lightweight cryptographic coprocessor is the primary design constraint for modern wireless Implantable Medical Devices (IMDs). The lightweight cryptographic ciphers are the preferred cryptographic solution for low-energy encryption. This article proposes 2-SPGAL, the 2-phase sinusoidal clocking implementation of Symmetric Pass Gate Adiabatic Logic (SPGAL) for IMDs. The proposed 2-SPGAL is energy-efficient and secure against the Correlation Power Analysis (CPA) attack. The proposed 2-SPGAL was evaluated with the integration of synchronous resonant Power Clock Generators (PCGs): (i) 2N2P-PCG, and (ii) 2N-PCG. The case study implementation of one round of PRESENT-80 encryption using 2-SPGAL, with 2N2P-PCG integrated into the design, shows an average of 47.50% of energy saving compared to its CMOS counterpart, over the frequency range of 50 kHz to 250 kHz. The same 2-SPGAL based case study, with 2N-PCG integrated into the design, shows 51.18% of an average energy saving compared to its CMOS counterpart, over 50 kHz to 250 kHz. Further, the 2-SPGAL based PRESENT- 80 one round shows an average energy saving of 16.62% and 28.90% respectively for 2N2P-PCG and 2N-PCG integrated into the design compared to existing 2-phase adiabatic logic called 2- EE-SPFAL. We also subjected PRESENT-80 design of 2-SPGAL and CMOS against CPA attack. The 2-SPGAL, with 2N2P-PCG and 2N-PCG, integrated into one round of PRESENT-80 design protects the encryption key. However, the encryption key was successfully revealed in one round of PRESENT-80 design using CMOS logic. Therefore, the proposed 2-SPGAL logic can be useful to design energy-efficient and CPA resilient Implantable Medical Devices (IMDs).  more » « less

    The adaptation of the Internet-of-Things (IoT) for consumer electronics has enabled us to uplift everyday life. Low-power smart and secure computing devices are needed to sustain the expected growth of consumer IoT. Adiabatic switching is a modern approach that recycles the energy stored in load capacitance to save energy. Further, the cryptographic circuit designed using adiabatic switching is secure against the Correlation Power Analysis (CPA) attack in contrast to the same circuit designed using standard CMOS. In this paper, we propose 2-SPGAL, a 2-phase sinusoidal signal based clocking implementation of Symmetric Pass Gate Adiabatic Logic (SPGAL). As a case study, we simulated the design of PRESENT-80 (a lightweight cryptographic scheme) one round with an in-built Power Clock Generator (PCG) with 45nm technology. The 2-SPGAL shows on an average 82.76% and 67.35% better energy saving compared to standard CMOS, and 2-EE-SPFAL (another 2-phase adiabatic logic), respectively at a frequency range from 100 kHz to 25 MHz with a load of 1 fF. The 2-SPGAL has 16.78% savings of the number of transistors compared to 2-EE-SPFAL for implementation of one round PRESENT-80. Further, the CPA attacks reveal the key in standard CMOS, however, 2-SPGAL PRESENT-80 adiabatic logic design was successful to protect the key.

    Smart consumer electronic devices are mostly area constrained and operate on a limited battery supply and therefore, have tight energy budgets. Lightweight Cryptography (LWC) such as PRESENT-80 allows for minimal area usage and low energy for secure operations. However, CMOS implemented LWCs are vulnerable to side-channel attacks such as Correlation Power Analysis (CPA). Adiabatic Logic is an emerging circuit design technique that can reduce energy consumption and be CPA resistant. Many existing adiabatic logic families use a 4-phase clocking scheme which pays a large area penalty. Thus, in this article, we introduce 2-EESPFAL, a 2-phase clocking scheme implementation of an existing adiabatic family known as EE-SPFAL. To show the applicability of 2-EE-SPFAL, we construct a 2-phase clock generator that remains energy efficient and secure. From 100 kHz to 25 MHz, our results show an average energy saving of 76.5% to 21.3% between CMOS and 2-EE-SPFAL. As a case study, we performed a CPA attack on both the CMOS and 2-EE-SPFAL implementation of PRESENT-80 and determined that the CMOS key could be retrieved while the adiabatic key was kept hidden.

We explore 2-phase sinusoidal waves in terms of energy efficiency and security. To demonstrate energy savings and security against CPA attacks we construct one round of PRESENT-80 in both CMOS and 2-EE-SPFAL. Simulations were conducted using 45nm technology in Cadence Spectre. At 12.5MHz, our results show an average energy saving of 50% between CMOS and 2-EE-SPFAL. Furthermore, we performed a CPA attack on both the CMOS and 2-EE-SPFAL implementation and determined that the CMOS key could be retrieved while the adiabatic key was kept hidden.

    Internet of Things (IoT) devices have strict energy constraints as they often operate on a battery supply. The cryptographic operations within IoT devices consume substantial energy and are vulnerable to a class of hardware attacks known as side-channel attacks. To reduce the energy consumption and defend against side-channel attacks, we propose combining adiabatic logic and Magnetic Tunnel Junctions to form our novel Energy Efficient-Adiabatic CMOS/MTJ Logic (EE-ACML). EE-ACML is shown to be both low energy and secure when compared to existing CMOS/MTJ architectures. EE-ACML reduces dynamic energy consumption with adiabatic logic, while MTJs reduce the leakage power of a circuit. To show practical functionality and energy savings, we designed one round of PRESENT-80 with the proposed EE-ACML integrated with an adiabatic clock generator. The proposed EE-ACML-based PRESENT-80 showed energy savings of 67.24% at 25 MHz and 86.5% at 100 MHz when compared with a previously proposed CMOS/MTJ circuit. Furthermore, we performed a CPA attack on our proposed design, and the key was kept secret.

    The tremendous growth in the number of Internet of Things (IoT) devices has increased focus on the energy efficiency and security of an IoT device. In this paper, we will present a design level, non-volatile adiabatic architecture for low-energy and Correlation Power Analysis (CPA) resistant IoT devices. IoT devices constructed with CMOS integrated circuits suffer from high dynamic energy and leakage power. To solve this, we look at both adiabatic logic and STT-MTJs (Spin Transfer Torque Magnetic Tunnel Junctions) to reduce both dynamic energy and leakage power. Furthermore, CMOS integrated circuits suffer from side-channel leakage making them insecure against power analysis attacks. We again look to adiabatic logic to design secure circuits with uniform power consumption, thus, defending against power analysis attacks. We have developed a hybrid adiabatic-MTJ architecture using two-phase adiabatic logic. We show that hybrid adiabatic-MTJ circuits are both low energy and secure when compared with CMOS circuits. As a case study, we have constructed one round of PRESENT and have shown energy savings of 64.29% at a frequency of 25 MHz. Furthermore, we have performed a correlation power analysis attack on our proposed design and determined that the key was kept hidden.
