摘要： A client can communicate with a middle tier, which can then, in turn, communicate with a back end tier to access information and resources on behalf of the client within the context of a system that can scale well. Each individual back end can establish a policy that defines which computing device can delegate to that back end. That policy can be enforced by a domain controller within the same administrative domain as the particular back end. When a middle tier requests to delegate to a back end, the domain controller to which that request was directed can either apply the policy, or, if the domain controller is in a different domain than the targeted back end, it can direct the middle tier to a domain controller in a different domain and can sign relevant information that the middle tier can utilize when communicating with that different domain controller.

摘要： Modern network communications often require a client application requesting data to authenticate itself to an application providing the data. Such authentication requests can be redundant, especially in the case of stateless network protocols. When a full authentication is performed, a conversation identifier and one or more encryption keys can be agreed upon. Subsequent authentication requests can be answered with a fast reconnect token comprising the conversation identifier and a cryptographically signed version of it using the one or more encryption keys. Should additional security be desirable, a sequence number can be established and incremented in a pre-determined or a random manner to enable detection of replayed fast reconnect tokens. If the recipient can verify the fast reconnect token, the provider can be considered to have been authenticated based on the prior authentication. If an aspect of the fast re-authentication should fail, recourse can be had to the original full authentication process.

摘要翻译： 现代网络通信通常需要客户端应用程序请求数据对提供数据的应用程序进行身份验证。 这种认证请求可以是冗余的，特别是在无状态网络协议的情况下。 当执行完整认证时，可以同意会话标识符和一个或多个加密密钥。 随后的认证请求可以用包括会话标识符的快速重新连接令牌和使用该一个或多个加密密钥的加密签名版本来应答。 如果需要额外的安全性，则可以以预定或随机的方式建立和递增序列号，以便能够检测重放的快速重新连接令牌。 如果收件人可以验证快速重新连接令牌，则可以认为提供商已经根据先前的身份验证进行了身份验证。 如果快速重新认证的一个方面应该失败，则可能需要对原始的完整身份验证过程进行追索。

Additionally, the method includes, if the current-sensing signal related to the first predetermined frequency is determined to be larger than the first threshold in magnitude at anytime during a first period of time, changing the signal frequency from the first predetermined frequency to a second predetermined frequency, the second predetermined frequency being different from the first predetermined frequency.
