VERFAHREN UND SYSTEM ZUR AUTHENTIFIZIERUNG IN EINEM COMPUTERNETZWERK

摘要

Method and system for authentication in a computer network is provided. A first message from a client to a server is transmitted, where the first message includes erroneous user information. In response to the first message, a second message is transmitted from the server to the client, where the second message includes an error message and a nonce. The client transmits a third message to the server in response to the second message, where the third message includes non-erroneous user information and the nonce. The server then provides authentication in response to the client's third message.
