Encrypted communication security module special for power

Abstract

The invention aims to provide an encrypted communication security module special for power that satisfies the requirements of distribution network terminals, small hydropower generation data collection and marketing smart electric meter data collection, can be directly embedded into various types of terminals and instruments in a security module manner, and can meet various types of application requirements. The security module includes a security encryption CPU using an SOC architecture, wherein the security encryption CPU extends a plurality of interfaces through bus and serial port resources, the plurality of interfaces include a power interface connected to an external power supply, a storage interface of external storage equipment, an input interface and an output interface, the inputinterface is a serial port or a network interface, the output interface is a network interface or a GPRS interface, the network interface and / or the GPRS interface are / is provided with a network isolation transformer, the serial port is provided with an isolated RS232 conversion chip, the power interface is provided with an EMC circuit and an anti-reverse circuit, and the input interface and theoutput interface are both provided with an anti-DOS attack module. The invention can be applied to the field of security communication.

Description

technical field [0001] The invention relates to the field of secure communication, in particular to a power-specific encrypted communication security module. Background technique [0002] Because the power system communication application uses public network communication, there are many collection points at the same time, such as distribution network terminal data collection, smart meter data collection, small hydropower generation data collection, etc. Due to the large number of collection points, which are widely distributed, many collection points do not have physical lines to reach them. In order to save costs, the power sector usually realizes data collection by renting public network communication. But this will lead to the harm of public network communication to data. At present, there are various communication protection devices for the public network on the market, but the application has limitations, the implementation methods are also different, the cost remains...
