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…
Secure Millimeter-Wave Ad Hoc Communications Using Physical Layer Security
Yuanyu Zhang, Yulong Shen, Xiaohong Jiang +1
Millimeter-wave (mmWave) communications are highly promising to improve the capacity of modern wireless networks, while the physical layer security (PLS) techniques hold great pote…
Enumerating Graph Partitions Without Too Small Connected Components Using Zero-suppressed Binary and Ternary Decision Diagrams
Yu Nakahata, Jun Kawahara, Shoji Kasahara
Partitioning a graph into balanced components is important for several applications. For multi-objective problems, it is useful not only to find one solution but also to enumerate…
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…
Mode Selection and Spectrum Partition for D2D Inband Communications: A Physical Layer Security Perspective
Yuanyu Zhang, Yulong Shen, Xiaohong Jiang +1
This paper investigates from the physical layer security (PLS) perspective the fundamental issues of mode selection and spectrum partition in cellular networks with inband device-t…
Effect of Bitcoin fee on transaction-confirmation process
Shoji Kasahara, Jun Kawahara
In Bitcoin system, transactions are prioritized according to transaction fees. Transactions without fees are given low priority and likely to wait for confirmation. Because the dem…
