  • Energy analysis of public-key cryptography for wireless sensor networks
    Third IEEE International Conference on Pervasive Computing and Communications, 2005
    Co-Authors: Arvinderpal S Wander, N. Gura, Hans Eberle, Vipul Gupta, Sheuelling Chang Shantz, Sun Microsystems Laboratories

    Abstract:

    In this paper, we quantify the energy cost of authentication and key exchange based on public-key cryptography on an 8-Bit Microcontroller platform. We present a comparison of two public-key algorithms, RSA and elliptic curve cryptography (ECC), and consider mutual authentication and key exchange between two untrusted parties such as two nodes in a wireless sensor network. Our measurements on an Atmel ATmega128L low-power Microcontroller indicate that public-key cryptography is very viable on 8-Bit energy-constrained platforms even if implemented in software. We found ECC to have a significant advantage over RSA as it reduces computation time and also the amount of data transmitted and stored.

  • Control of a Single-Phase PFC Preregultaor using an 8-Bit Microcontroller
    APEC 07 – Twenty-Second Annual IEEE Applied Power Electronics Conference and Exposition, 2007
    Co-Authors: Yijing Chen, Dake He, R.m. Nelms

    Abstract:

    Presented in this paper is a hybrid power factor correction (PFC) preregulator controlled by a single Microcontroller. By using the on-board peripherals of this Microcontroller, no complex algorithm or external multiplier was required to perform the PFC function correctly, and thus a one-chip solution has been achieved. The proposed hybrid PFC preregulator has been tested in the laboratory. The measured power factor was above 0.99, and the output voltage was precisely controlled. Experimental results also indicate that the hybrid PFC preregulator can operate satisfactorily over a range of input voltages and output loads. The results presented in this paper demonstrate that it is possible to implement a high performance PFC preregulator using a single Microcontroller without more expensive DSPs or other complicated hardware. Because of the simplicity of the circuit, the proposed PFC preregulator has low cost and high reliability.

  • Fuzzy logic peak current-mode control for dc-dc converters using an inexpensive 8-Bit Microcontroller
    Twentieth Annual IEEE Applied Power Electronics Conference and Exposition 2005. APEC 2005., 2005
    Co-Authors: D. He, R.m. Nelms

    Abstract:

    Described in this paper are the design and implementation of a Microcontroller-based fuzzy logic peak current-mode controller (PCMC) for dc-dc converters. A fuzzy logic PCMC boost converter operating in the continuous conduction mode has been designed using an 8-Bit Microcontroller. A one-chip solution has been achieved. No complex algorithm is required to estimate the controlled current by using the on-board peripherals of the Microcontroller. The fuzzy logic algorithm uses a rule-based description of converter operation. By using rule-based look-up tables and other techniques, the fuzzy logic algorithm is implemented on the low-cost Microcontroller successfully. Experimental results indicate successful operation of the Microcontroller-based fuzzy logic PCMC power converter system.
