CSI Phase Averaging for High-Sensitivity Wi-Fi Sensing in Low-Multipath Environments
Toshinori Suzuki, Shin-ichiro Ogura, Yu Morishima +1
This paper presents a low-complexity motion detection method for outdoor Wi-Fi sensing based on a model-driven approach. The method exploits the structural characteristics of the p…
A True Random Number Generator Method Embedded in Wireless Communication Systems
Toshinori Suzuki, Masahiro Kaminaga
To increase the number of wireless devices, e.g., mobile or IoT terminals, cryptosystems are essential for secure communications. In this regard, random number generation is crucia…
Determining the Optimal Random-padding Size for Rabin Cryptosystems
Masahiro Kaminaga, Toshinori Suzuki, Masaharu Fukase
Rabin encryption and a secure ownership transfer protocol based on the difficulty of factorization of a public key use a small public exponent. Such encryption requires random numb…
Crashing Modulus Attack on Modular Squaring for Rabin Cryptosystem
Masahiro Kaminaga, Hideki Yoshikawa, Arimitsu Shikoda +1
The Rabin cryptosystem has been proposed protect the unique ID (UID) in radio-frequency identification tags. The Rabin cryptosystem is a type of lightweight public key system that…
