General Ethernet encryption interface module supporting IPv6

Abstract

The invention discloses a general Ethernet encryption interface module supporting IPv6, which is composed of two network interface chips, a microprocessor, an encryption chip and a clock generator, wherein, four data buses of the microprocessor are respectively physically connected with the network interface chip, the network interface chip, the encryption chip and a user general bus; the clock generator is connected with the clock interface of the microprocessor so as to provide a synchronous clock signal for the microprocessor; the network end of the first network interface chip is connected with an IPv4 network, which realizes encryption and decryption of MAC and a PHY protocol layer in the IPv4 network; the network interface of the other network interface chip is connected with an IPv6 network to realize encryption and decryption of MAC and a PHY protocol layer in the IPv6 network. The invention solves the problems of seriously insufficient address resource and data safety caused by the internet IPv4 protocol for a long term and solves the difficulty of complex software programming and component-based design in IPv6 practical application, which ensures that people can connect any object in the world via the Internet.
