Abstract

The invention provides an SDN network multicast member information encryption method and system, a terminal and a storage medium. The SDN network multicast member information encryption method comprises the steps of encrypting identity information of an update member to obtain encrypted identity information; updating secret key information according to the updated member identity information and encrypting the encrypted identity information and the secret key updating information to obtain encrypted updating information; and issuing the encrypted update information to the user node, wherein the encrypted update information is used for the user node to update the key group. According to the method disclosed in te invention, after the multicast member is changed, the identity information ofthe updating member is ensured to be in an encrypted state when the user key is updated by the key management server GCKS, the data is stolen in the key updating process, the identity information of the updating member is not leaked, and the privacy of the updating member is reliably protected.

Description

technical field [0001] The invention relates to the technical field of SDN network multicast, in particular to a method, system, terminal and storage medium for encrypting SDN network multicast member information. Background technique [0002] SDN (Software Defined Networking) is a new type of network architecture, originally proposed by Stanford University in the United States. The biggest difference between SDN and traditional networks lies in the control mode of the network. Its core technology is to separate the control function of network equipment from the data forwarding function. On the other hand, it realizes the transparency of the underlying infrastructure to the upper application, and has resource virtualization and software programmability. [0003] Multicast is a network technology that allows one or more senders (multicast sources) to send a single data packet to multiple receivers. The multicast source sends data packets to a specific multicast group, and o...
