<p>The present invention relates to a method, device and system for data security transmission/reception in a pseudo-wire (PW) network. The data security transmission method includes: receiving an original message transmitted from a terminal (S201); according to a pre-negotiated security attribute, performing security processing for the received original message to generate a security message (S202); performing a pseudo-wire encapsulation processing for the generated security message to generate an encapsulated security message (S203); transmitting the encapsulated security message through a pre-established pseudo-wire tunnel (S204). The present invention overcomes the problem of information insecurity in the prior art of the PW transmission technology, realizes the security protection function of data during the PW transmission forwarding, solves the technical blank space for performing security protection processing for the transmission data in the PW, is not limited to Internet Protocol/Transfer Control Protocol (IP/TCP) messages and is widely applied, so as to perform security protection processing for the existing and future visible various kinds of messages.</p> |
