Abstract
A two-party stateless protocol by which a server receives a request from a client, transmits a tamper-resistant challenge to the client, receives a response to the challenge, and validates the response, where each of the challenge and the response contain a copy of the request. If the client responds correctly to the challenge and does not modify the request during the protocol, the server executes the request.
