Abstract
A method for content delivery network (CDN) inter-node encryption by a CDN node includes receiving a symmetric key set and a key index from a key center, determining a key from the symmetric key set according to the key index, and performing encryption and decryption processing using the key when performing Hyper Text Transfer Protocol (HTTP) data transmission with another CDN node.
