Let's Encrypt AI: protect AI chats with on AI GPUs by the end of 2027

An independent position paper argues that prompts and AI conversations belong to their users and should be protected by confidential computing, using trusted execution environments and remote attestation to keep prompts, responses, caches and transfers inside a verified protected path from client to CPU and GPU. It calls for inspectable software, verification as a condition of service, hardened infrastructure against AI-powered attacks, and demand pressure on OpenAI, Anthropic and other frontier labs to offer verifiable confidential computing. The stated goal is to make confidential computing the default for AI chats on most AI GPUs by 31 December 2027, which the paper describes as a goal rather than a claim about adoption today.
