Offline Decryption Messaging is a proposed security model designed to protect communications even when online devices are compromised by spyware. It uses two devices per user: an online device for transmitting encrypted messages and an air-gapped offline device for writing, encrypting, decrypting, and displaying messages. This separation ensures that spyware on the online device cannot access plaintext messages or cryptographic keys, while spyware on the offline device cannot exfiltrate data due to lack of network connectivity. The concept aims to address the limitations of traditional end-to-end encrypted messengers like Signal, which become ineffective if the device itself is compromised. The project, called HelioSphere, is in early prototype stages and seeks community feedback on security, usability, and cryptographic improvements. While promising for high-risk users such as activists, the approach introduces operational complexity and usability challenges. No known exploits exist yet, and the threat is currently a conceptual proposal rather than an active attack vector.
