Abstract
Due to the 4th industrial revolution and the strength of the 5 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> Generation (5G) era, the Internet of Things (IoT) industry is growing significantly. As a result, the number of IoT devices in various industries, such as smart cars, smart homes, and smart healthcare, and the importance of security for these devices are increasing. This study proposes a design method for a secure cryptographic system on a chip (SecSoC) that can be used in the IoT industry and presents the results of the performance and security evaluations of the implemented chipset. The experimental results demonstrated that the SecSoC is a low-power high-performance cryptographic chip that is safe from external attacks. Compared to conventional smart card integrated circuits, the proposed design includes intrusion detection circuits that can respond to external attacks. At the same time, it supports a physical unclonable function for hiding secret data and cryptographic logic for maintaining integrity and confidentiality. The SecSoC ensured a fast transfer rate up to 110 Mbps and consumed only 95.8 mW when operating at maximum frequency.
Highlights
Today, the prevalence of Internet of Things (IoT) devices is increasing exponentially [1]
WORK This study proposes an system on a chip (SoC) design method that integrates the cryptographic module used in IoT, the defense logic used against external attacks for hardware security, and the physical unclonable function (PUF) used to hide secret data in a chip
Since the static random-access memory (SRAM) PUF is a strong PUF in which a challenge-response pair exists in proportion to the memory size, it is designed to detect external attacks using sensors so that the key value determined by the PUF cannot be tampered with by outside users
Summary
The prevalence of Internet of Things (IoT) devices is increasing exponentially [1]. Attackers can reverse-engineer smart card integrated circuits (ICs) and change the operation modes of these circuits using information acquired from using overvoltage, light, and environmental stimuli (e.g., temperature and frequency), manipulating data, or duplicating the master key in the memory [12][13][14][15] These methods can cause malfunctions in security circuits that have specific cash cards or functions that permit access [16]. To resolve such issues, we designed a secure cryptographic system on a chip (SecSoC) with sensors for intrusion detection and a physical unclonable function (PUF) to hide secret data integrated on an IoT cryptographic chip using hardware security technology.
