Dexcom G7 User Manual page 137

In addition to the security provided by the BLE connection, communication between
the G7 transmitter, G7 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 industry standard encryption protocols and
methods to protect data, verify data integrity, and to detect and prevent data
tampering.
Unless disabled, the G7 mobile application regularly communicates with Dexcom
Servers. Both the G7 mobile application and communication between the G7
applications and Dexcom Servers are protected by a number of mechanisms,
designed to safeguard against data corruption. All such communication takes place
exclusively over an encrypted data path.
