Latest Patents

Long Cheng holds a patent for a method titled "Cloud-based forensic IP traceback." This invention involves receiving a traceback request that includes the identity of a traceback-deployed autonomous system closest to the destination node in a network routing path. The method further includes recursively querying a traceback server associated with the traceback-deployed autonomous system to obtain the identity of a preceding traceback-deployed autonomous system in the network routing path. Additionally, the invention determines the network routing path based on the received identities of traceback-deployed autonomous systems. Authentication for the traceback request is achieved using token delivery, where the token is fragmented, and marking of a packet is performed when a field on the packet matches at least one token fragment. Long Cheng has 1 patent to his name.
