简化的音频验证的方法和设备
摘要：
声明了一种用于验证的设备和方法，带有一处理器（208）以及至少一个耦合到处理器（208）的执行器。签名发生器耦合到处理器（208）并能生成安全标识符。发射器耦合到能发送安全标识符的信号发生器。接收机接收发送的安全标识符并确认安全标识符被合适地发送了。对应发送的密钥标识符的公共密钥被访问以使用访问的密钥确定安全标识符的有效性，并且接收到的安全标识符内指明的时间经验证在可接受的时间容差内。
摘要（英）：

An apparatus and method for authentication having a processor (208) and at least one activator coupled to the processor (208) is claimed. A signature generator is coupled to the processor (208) and capable of generating a secure identifier. An emitter coupled to the signal generator capable of emitting the secure identifier. A receiver receives the emitted secure identifier and verifies that the secure identifier was appropriately transmitted. The public key corresponding to the key identifier transmitted is accessed to determine the validity of the secure identifier using the accessed key and that the time indicated in the received secure identifier is verified to be within acceptable time tolerances.
