Quick Answer
To ensure encrypted communication via goTenna, use the goTenna Mesh app's built-in encryption features, such as AES-128 encryption, and set up a secure network with trusted contacts. This will enable end-to-end encryption and secure messaging. Additionally, use goTenna's Private Messaging feature to send encrypted messages.
Secure Network Setup
To set up a secure network on goTenna Mesh, create a new network and invite trusted contacts. When sending an invitation, select the “Private Network” option to enable encryption. Each member must have the goTenna Mesh app and be connected to the network to participate in secure communication. A maximum of 50 members can be part of a single private network.
Encryption Techniques
goTenna Mesh app offers two encryption techniques: AES-128 encryption and Elliptic Curve Diffie-Hellman (ECDH) key exchange. AES-128 encryption is used for message encryption, while ECDH key exchange establishes a secure connection between users. To enable AES-128 encryption, navigate to the app’s settings and select “Advanced” > “Encryption” > “AES-128”. This will ensure all messages sent within the network are encrypted.
Additional Security Measures
To further enhance security, use goTenna’s Private Messaging feature, which allows users to send encrypted messages to specific individuals. Private Messaging uses a unique key for each conversation, ensuring that even if a network is compromised, messages sent via Private Messaging remain secure. To enable Private Messaging, select the “Private Message” option when composing a message, and enter the recipient’s goTenna ID.
