Abstract

The invention discloses a public network communicating security gateway dedicated for electric power, aims at providing a public network communicating security gateway dedicated for electric power which has convenient communication, safe use, dedicated equipments with multiple emergent data transmission channels, and is not easy to be attacked, and comprises at least a modem (1), a computer mainboard (2), a network card interface (4), a USB external interface (5), a telephone line interface (6), a power source (7), a managing and configuring modular device, a PPP network access module device, an authenticating module device, a VPN module device, a communicating protocol rules auditing module device dedicated for electric power and a network serial port converting module device, and all the module devices are arranged on the computer mainboard (2). The public network communicating security gateway dedicated for electric power can be widely applied in the field of network communication with high security and low speed requirements.

Description

technical field [0001] The invention relates to an electric power dedicated public network communication security gateway. Background technique [0002] At present, IPSec-VPN occupies a dominant position in VPN technology, but most IPSec-VPN products establish connections through the Internet. Compared with the telephone network, the security threats on the Internet are much greater, and the transmission of data and information is also more complex. It is easy to be found and attacked. When the connection is established by telephone dial-up, the allocation of the PPP dial-up IP address is dynamically allocated by the telecommunications public network, and the IP address obtained by each dial-up connection is different, and such communication is very inconvenient. More importantly, the obtained IP address will be exposed on the public Internet, which poses a threat to the overall security of the system and provides opportunities for attacks. And because the existing power c...
