The development of vehicle technologies such as connected and autonomous vehicle
environments provide drivers with functions for convenience and safety that are highly …

The urgent requests to protection integrated circuits (IC) and hardware intellectual properties
(IP) have led to the development of various logic obfuscation methods. While most existing …

Scan-based side-channel attacks retrieve a secret key in a cryptography circuit by analyzing
scanned data. Since they must be considerable threats to a cryptosystem LSI, we have to …

Assigning bug reports to individual developers is typically a manual, time-consuming, and
tedious task. In this paper, we present a framework for automated assignment of bug-fixing …

Insertion of scan chains is the most common technique to ensure observability and
controllability of sequential elements in an IC. However, when the chip deals with secret …

The conflict between security and testability is still a concern of hardware designers. While
secure devices must protect confidential information from unauthorized users, quality testing …

Scan test which is one of the useful design for testability techniques is effective for LSIs
including cryptographic circuit. It can observe and control the internal states of the circuit …

Cryptography chips are often used in some applications, such as smart grids and Internet of
Things (IoT) to ensure their security. Cryptographic chips must be strictly tested to guarantee …

In this paper, we outline security issues on IEEE 1149.1 JTAG. The JTAG interface is
provided for its beneficial features, such as debugging and downloading firmware, but …

Scan test is the standard method, practiced by industry, that has consistently provided high
fault coverage due to high controllability and high observability. The scan chain allows to …
