标准摘要
[中文适用范围]： 本文件规定了广播认证协议，即在广播环境下提供数据完整性和实体身份验证的协议。在这种环境中，一个发送方向多个接收方传输消息。 为了提供身份验证，必须存在预先存在的基础设施，将发送方与加密密钥相关联。此类基础设施的建立超出了本文件的范围。 [外文原描述]： This document specifies broadcast authentication protocols, which are protocols that provide data integrity and entity authentication in a broadcast setting, i.e. a setting with one sender transmitting messages to many receivers. To provide entity authentication, there needs to be a pre-existing infrastructure which links the sender to a cryptographic secret. The establishment of such an infrastructure is beyond the scope of this document.
