高效兼安全型电表数据收集系统
摘要：
本发明涉及通信技术领域，具体公开了一种高效兼安全型电表数据收集系统，本系统通过数据收集器接收智能读表器发送的加密电表数据后解密并编码，然后选取部分解密编码的电表数据进行二次加密，并将这部分二次加密且具有编码的电表数据以及未进行二次加密的具有编码的电表数据发送给能源管理终端，所述能源管理终端对二次加密且具有编码的电表数据进行解密解码、并对未进行二次加密的具有编码的电表数据进行解码得到用户的电表数据信息，既保证了通信数据的安全性，同时由于ES处仅需解密部分个编码且加密的消息，因此又降低了ES处的解密复杂度。
摘要（英）：

The invention relates to the technical field of communication, and particularly discloses an efficient and secure electricity meter data collection system. The system receives encrypted electricity meter data sent by a smart meter reader through a data collector, decrypts and encodes the data, and then selects part of the decrypted and encoded electricity meter data to perform secondary encryption, and transmits this part of electricity meter data that is subjected to secondary encryption and is encoded and the electricity meter data that is not subjected to secondary encryption and is encodedto an energy management terminal; and the energy management terminal decrypts and decodes the electricity meter data that is subjected to secondary encryption and is encoded, and decodes the electricity meter data that is not subjected to secondary encryption and is encoded to obtain electricity meter data information of a user. Thereby, the security of communication data can be ensured, and meanwhile, as an ES only needs to decrypt part of encoded and encrypted messages, the decryption complexity of the ES can also be reduced.
