Problems solved by technology

[0004] At present, VXLAN adopts the way of transmitting data in clear text, which creates certain security risks for using VXLAN to transmit data across regions. Therefore, as a gateway device provider, it has become a practical demand to provide a VXLAN mode that supports encrypted data transmission.

Embodiment Construction

[0051] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific implementations are now described in detail.

[0052] VXLAN uses plain text to transmit data. There are certain security risks for using VXLAN to transmit data across regions. Therefore, it is necessary to provide a method that supports encrypted data transmission in VXLAN mode.

[0053] like figure 1 As shown, the gateway VXLAN can choose the encrypted data transmission method, and the VXLAN local end negotiation can choose encrypted data transmission. Before the local end that supports VXLAN encrypted data transmission sends data to the opposite end, it first tries to negotiate the encryption option, and starts data encryption after the negotiation is successful. transmission, including the following steps:

[0054] 1) The VXLAN local end sends an optional encryption request message to the peer end;

[0055] 2) The VXLAN local end waits for the...

Abstract

The invention relates to a method for a gateway VXLAN to select encrypted data transmission. VXLAN local end negotiation can select encrypted data transmission. Before sending data to the opposite end, the local end that supports VXLAN encrypted data transmission first tries to negotiate the encryption option, and starts data encryption after the negotiation is successful. Transmission, the steps are: the VXLAN local end sends an optional encryption request message to the peer end; the VXLAN local end waits for an optional encrypted response message; the VXLAN local end sends an encrypted message in plain text to the peer end; the VXLAN local end waits for the key Negotiation result message; after negotiation, the VXLAN local end sends data packets. Realize that VXLAN supports encrypted negotiation and data transmission. The gateway enables the VXLAN function and negotiates with the peer VTEP whether to choose encryption; the gateway and the peer negotiate encryption detailed configuration and confirm the consistency of the key; the gateway and the peer start encrypted data transmission; Choose to use symmetric encryption, which has high security.

Description

technical field [0001] The invention relates to a method for a gateway VXLAN to selectively encrypt data transmission. Background technique [0002] At present, VXLAN (Virtual eXtensible Local Area Network) is a tunneling technology that can establish a layer-2 Ethernet network tunnel on the basis of a layer-3 network, thereby realizing cross-regional layer-2 interconnection. [0003] VXLAN adopts the encapsulation format of encapsulating original Ethernet packets in UDP packets. Encapsulate the original Layer 2 data frame plus the VXLAN header into a UDP packet. The VXLAN header contains a VXLAN identifier (VNI, VXLAN Network Identifier), and only virtual machines on the same VXLAN can communicate with each other. [0004] At present, VXLAN adopts the way of transmitting data in plain text, which creates certain security risks for the use of VXLAN to transmit data across regions. Therefore, as a gateway equipment provider, it has become a practical demand to provide a VXL...
