此外，本方案在不排除网内处理和节点被动加入的情况下，支持数据源认证。
In addition, the proposed scheme also supports source authentication without precluding in-network processing and passive participation.
而组播数据源认证又是整个安全组播通信中的重点和难点问题，也是真正实现安全组播通信的基础和前提。
Source authentication is the key and difficulty problem through the multicast. And it also become the basis and precondition for realizing the security multicast.
该文按照协议分类分别概述了几个具有代表性的不可否认数据源认证协议，并对每一个协议的优缺点和存在问题进行了讨论。
In this paper, several typical data origin authentication protocols with non-repudiation are summarized according to the taxonomy of data origin authentication with non-repudiation.
这里提出了一种一次签名方案，它是一种对于签名生成和签名验证都极为高效的方案，而且签名长度很短，特别适用于组播通信的数据源认证。
We propose a one-time signature scheme with very efficient signing and verifying, and short signatures. Our scheme is well-suited for multicast source authentication.
为了避免为每个数据源一一执行用户认证，可以利用单点登录。
To avoid having to authenticate the user for each data source, single sign-on techniques can be leveraged.
接下来，可以创建用户映射以便在需要时将远程认证信息注册到数据源
Next, you can create a user mapping to register remote authentication information to the data sources if necessary
从任何给定的数据源检索数据通常都需要进行一些初始化活动，例如连接到数据源和提供有效的认证信息。
Retrieving data from any given source usually requires some initialization activities, such as connecting to a data source and providing valid authentication information.
在远程认证注册后，如果数据源的pass -through受支持，那么可以用它来测试到那个数据源的连接。
After remote authentication registration, if pass-through is supported for the data source, you can use it to test the connection to that data source.
其接收数据经认证数据源及检验数据完整性，使有效数据送入数据分发层地址。
The received data was authenticated data integrality was verified, and so that valid data were sent into the address of distributing data layer.
