Opportunistic Wiretapping/Jamming: A New Attack Model in Millimeter-Wave Wireless Networks
Yuanyu Zhang, Zhumeng Zheng, Ji He +4
While the millimeter-wave (mmWave) communication is robust against the conventional wiretapping attack due to its short transmission range and directivity, this paper proposes a ne…
Combining IOTA and Attribute-Based Encryption for Access Control in the Internet of Things
Ruka Nakanishi, Yuanyu Zhang, Masahiro Sasabe +1
Unauthorized resource access represents a typical security threat in the Internet of things (IoT), while distributed ledger technologies (e.g., blockchain and IOTA) hold great prom…
Attribute-Based Access Control for Smart Cities: A Smart Contract-Driven Framework
Yuanyu Zhang, Mirei Yutaka, Masahiro Sasabe +1
Efficient and reliable access control in smart cities is critical for the protection of various resources for decision making and task execution. Existing centralized access contro…
Smart Contract-Based Access Control for the Internet of Things
Yuanyu Zhang, Shoji Kasahara, Yulong Shen +2
This paper investigates a critical access control issue in the Internet of Things (IoT). In particular, we propose a smart contract-based framework, which consists of multiple acce…
Exploring Relay Cooperation for Secure and Reliable Transmission in Two-Hop Wireless Networks
