Abstract (in Japanese) (See Japanese page) 
(in English) Recent smart device OSs provide a hardware-backed key management system which uses TEE or secure elements.
To enable hardware-backed key management, it is necessary to build the device configurations by device makers.
Although many device makers and compositions exist in smart device markets, it is unclear about adoption rates of smart devices which can manage keys based on hardware.
In this paper, we investigated adoption rates of Android devices implemented hardware-backed key management by employing real device test services. We found that most devices were able to protect RSA keys by hardware, but some devices made EC and HMAC keys unsupported.
