Document Type and Number:
WIPO Patent Application WO/2021/065754
Kind Code:
A1
Abstract:
Provided is a data collection system comprising a host apparatus and a sensor apparatus for transmitting measured data to the host apparatus via a network, the data collection system being capable of secure communication between the host apparatus and the sensor apparatus and being capable of suppressing the power consumption of the sensor apparatus. A data collection system (1) is provided with a host apparatus (200) and a battery-driven sensor apparatus (100) for transmitting measured data (D) to the host apparatus via a network (20). The host apparatus has a cryptographic key generation unit (240) for generating a cryptographic key that is specific to the sensor apparatus, a storage unit (230) for storing the cryptographic key, a transmission unit (220) for transmitting the cryptographic key to the sensor apparatus using a public-key cryptography infrastructure, and a reception unit (210) for receiving the measured data of the sensor apparatus. The sensor apparatus has a reception unit (130) for receiving the cryptographic key transmitted by the host apparatus, a packet generation unit (160) for generating a packet that includes the measured data that has been encrypted by the cryptographic key, and a transmission unit (140) for transmitting the packet by broadcast.
