广电网络运营商在数字化整体转换后将发展的目光投向数字电视增值业务，随着各地增值业务平台的建成，明文传送的用户数据存在被窃取和篡改的可能，对它的加密受到广电运营商的重视，就现有的用户数据加密手段进行说明，同时对各种加密方式的流程进行设计，为广电网络运营商提供一个切实可行的思路。

The Consumer Data Encryption of Broadcast Television Two-way Network

After the digital conversion, broadcast television network operators will pay their attention on the digital TV value-added services. With the development of value-added services, the possibilities of stealing and tampering the consumer data come into being. So the encryption of the data is valued a lot by the opera- tors. This paper explains the existent encryption ways and designs the circuits of the various kinds of encryp- tion ways. It provides a feasible thinking for the operators.
