Security Measures
The G6 System is designed to transmit data between the transmitter and designated
display devices in accordance to the industry standard BLE protocols. It will not accept
radio frequency (RF) communications using any other protocol, including Bluetooth
classic communication protocols.
In addition to the security provided by the BLE connection, communication between
the G6 transmitter and the G6 receiver and mobile applications is protected by
additional levels of security and safety mitigations using an encrypted and proprietary
data format. This format embeds various methods to verify data integrity and to
detect potential instances of data tampering. While the format is proprietary, industry
standard encryption protocols (e.g., RSA and AES) are used in different parts of this
proprietary data format.
Unless disabled, the G6 mobile application regularly communicates with Dexcom
Servers. Communication between the G6 applications and Dexcom Servers is protected
by a number of mechanisms, designed to safeguard against data corruption. This
includes industry standard JWIT token based authentication and authorization. All
such communication takes place exclusively over encrypted data path using industry
standard SSL format.
