摘要： A method is disclosed for enabling stateless server-based pre-shared secrets. Based on a local key that is not known to a client, a server encrypts the client's state information. The client's state information may include, for example, the client's authentication credentials, the client's authorization characteristics, and a shared secret key that the client uses to derive session keys. By any of a variety of mechanisms, the encrypted client state information is provided to the client. The server may free memory that stored the client's state information. When the server needs the client's state information, the client sends, to the server, the encrypted state information that the client stored. The server decrypts the client state information using the local key. Because each client stores that client's own state information in encrypted form, the server does not need to store any client's state information permanently.
摘要翻译：公开了一种实现无状态的基于服务器的预共享秘密的方法。基于客户端不知道的本地密钥，服务器加密客户端的状态信息。客户端的状态信息可以包括例如客户端的认证凭证，客户端的授权特征以及客户端用于导出会话密钥的共享秘密密钥。通过各种机制中的任一种，加密的客户端状态信息被提供给客户端。服务器可以释放存储客户端状态信息的内存。当服务器需要客户端的状态信息时，客户端向客户端发送客户端存储的加密状态信息。服务器使用本地密钥解密客户端状态信息。因为每个客户端以加密的形式存储客户端自己的状态信息，服务器不需要永久地存储任何客户端的状态信息。
