Title:
METHOD, SYSTEM, DEVICE, MEDIUM AND DEVICE FOR CDN INTER-NODE ENCRYPTION
Document Type and Number:
WIPO Patent Application WO/2018/145606
Kind Code:
A1
Abstract:
Disclosed are a method, a system, and a device used for CDN inter-node encryption. The method comprises: generating a symmetric key set and a key index by a key center, and sending the symmetric key set and the key index to each content distribution network (CDN) node; the CDN node receiving the symmetric key set and the key index from the key center, determining the key from the symmetric key set according to the key index, and using this key to perform encryption and decryption processing when performing hypertext transfer protocol (HTTP) data transmission with other CDN nodes. This method skips the HTTPS handshake process that consumes mostly and utilizes the controllable characteristics of both end nodes to directly use the symmetric key, realizes a lightweight encryption process, achieves the same encryption effect as a standard HTTPS, reduces encryption overhead between CDN edge nodes and secondary nodes and reduces a load on the server at both ends.
