Abstract
Lightweight cryptography (LWC) plays an important role to ensure integrity, confidentiality, and security of sensitive information on devices with limited resources, such as internet of things (IoT) and wireless sensor networks. In our project, we aim to (i) explore hardware-efficient realizations of lightweight cryptography algorithms taking into account performance, power, and area (PPA) requirements; (ii) secure these implementations against well-known attacks, such as side-channel analysis and fault injection, considering the PPA overhead; and (iii) demonstrate these LWC designs in an application-specific integrated circuit (ASIC) and embed them in a real-world IoT environment.

Description
The research
An important shift from mainframe and personal computing to computing at edge nodes has led to significant growth in interconnected IoT devices that process and communicate information to a mobile device or a server over a wireless network. However, these devices are constrained in terms of implementation area, size of storage allocation, data rate, and energy consumption. To secure communication in an IoT environment, many LWC primitives have been introduced and standardized by national and international organizations, satisfying the IoT device requirements.
The main goal of this project is to implement hardware-efficient and secure LWC algorithms in ASIC. In this project, we will consider the LWC standards, such as PRESENT, Chaskey, and ASCON, and explore the hardware-efficient realization of their main blocks in terms of area, delay, and power dissipation. We will also secure our implementations against well-known attacks, such as side channel analysis and fault injection, using masking, blinding, and fault detection and mitigation techniques, considering the hardware complexity. Moreover, we will implement promising LWC designs in ASIC and use them in a real-world application.
Responsibilities and (foreseen) tasks:
- Describe LWC algorithms using hardware description languages, synthesize using commercial logic synthesis tools, and simulate and verify their behavior using commercial simulation tools
- Design LWC algorithms in ASIC including front-end, back-end, and tape-out phases
- Apply side-channel and fault injection attacks in all phases
- Disseminate the research findings in journal and conference publications
Applicants should fulfill the following requirements:
- Master’s degree in Computer Science, Electrical Engineering, or Computer Engineering
- Knowledge of hardware description languages Verilog/VHDL
- Knowledge of hardware design techniques targeting high performance and low power dissipation
- Experience in digital system design at RTL using Verilog/VHDL on FPGA/ASIC
- Knowledge of cryptography algorithms including block ciphers and hash functions
- Knowledge of hardware security including side-channel analysis and fault injection attacks
(The following experience is beneficial: )
- Experience in programming with C/C++
- Experience in the design of cryptography algorithms in hardware
- Experience in scripting languages, such as Perl, Tcl, and bash
- Relevant publications on cryptography and/or hardware security
We offer:
- 4-year PhD position in one of the largest, most internationalized and leading university in Estonia
- An opportunity to do high-level research with fellow researchers in this field
- Opportunities for international conferences, research stays and networking with well-known universities and research centers in this field
