As the development of a viable quantum computer nears, existing widely used public-key cryptosystems, such as RSA, will no longer be secure. Thus, significant effort is being invested into post-quantum cryptography (PQC). Lattice-based cryptography (LBC) is one such promising area of PQC, which offers versatile, efficient, and high performance security services. However, the vulnerabilities of these...
The ubiquitous computing era is characterized by wide deployment of resource constraint devices. Secure communication between such devices encounters a big challenge due to their resource limitation. The lightweight cryptographic algorithms are developed to address this challenge. In this work, implementation of LBlock, a lightweight encryption algorithm is investigated in Altera DE1 FPGA board. The...
AES algorithm or Rijndael algorithm is a network security algorithm which is most commonly used in all types of wired and wireless digital communication networks for secure transmission of data between two end users, especially over a public network. This paper presents the hardware implementation of AES Rijndael Encryption and Decryption Algorithm by using Xilinx Virtex-7 FPGA. The hardware design...
The existing intentional electromagnetic interference (IEMI) fault injection method based on continuous sinusoidal wave has a difficulty in injecting faults at a specific operation or time. This means that the obtained faulty outputs do not always satisfy a specific condition (e.g., time or number of error bytes) for performing fault analysis such as differential fault analysis (DFA). This paper presents...
Hardware Trojan Threats (HTTs) are stealthy components embedded inside integrated circuits (ICs) with an intention to attack and cripple the IC similar to viruses infecting the human body. Previous efforts have focused essentially on systems being compromised using HTTs and the effectiveness of physical parameters including power consumption, timing variation and utilization for detecting HTTs. We...
