Lumo's zero-access encryption technology is the core mechanism of its privacy protection. This technology ensures that a user's chats are encrypted end-to-end from the moment they are generated, with only the user's device holding the decryption key. This is accomplished by encrypting all conversations on the user's local device before transmitting them to the Proton server, which only stores the encrypted data and cannot decrypt it for viewing. According to the article, this encryption method has three key advantages: first, Proton, as a service provider, does not have access to plaintext content; second, all data is stored in European data centers that comply with EU standards; and lastly, even if the server is compromised, an attacker will not be able to access valid information. The technology is a homologous encryption solution to Proton's mailboxes and has been verified by independent security organizations.
