用于通过与所述公共警报系统相关联的通信网络被传输一个或多个消息的验证，用于管理一个或多个公共密钥技术被公开。 在一个示例中，该方法包括以下步骤。 通信网络的计算设备获得密钥材料为至少在公共警报系统生成的消息中的一个来源。 所述计算装置还获取源的标识符。 公共密钥被从密钥材料，计算设备和所述标识符的所述源计算。 因此，使用源的相应私钥的数字签名，来验证从所述源接收的消息中的公共密钥可以由计算设备使用。 在一个示例中，计算设备包括用户设备。

Techniques for managing one or more public key used for verification of one or more messages are transferred through a communication network associated with the public warning system is disclosed. In one example, the method includes the following steps. Computing device of a communication network obtains the key material for at least one source of messages generated for the public warning system. The computing device also acquires the identifier of the source. The public key is computed by the computing device from the key material and the source of the identifier. Thus, digitally signed using the corresponding private key of the source, a public key to verify the message received from the source can be used by the computing device. In one example, a computing device comprises a user equipment.
