Patent number: 11704404Abstract: Embodiments of the present disclosure provide a method for control-flow integrity protection, including: changing preset bits of all legal target addresses of a current indirect branch instruction in a control flow of a program to be protected to be same; and rewriting preset bits of a current target address of the current indirect branch instruction to be same as the preset bits of the legal target addresses, so that the program to be protected terminates when the current target address is tampered with. By changing the preset bits of all the legal target addresses of the current indirect branch instruction to be same and rewriting the preset bits of the current target address to be consistent with the preset bits of the legal target addresses, traditional label comparison is replaced by the preset bit overlap operation, reducing performance overhead and improving attack defense efficiency.Type: GrantFiled: June 28, 2021Date of Patent: July 18, 2023Assignee: Institute of Informational Engineering, CACInventors: Dan Meng, Liwei Chen, Jinfeng Li, Cairui She, Gang Shi

Patent number: 10505759Abstract: In an example, a network device may receive a L3VPN packet of which an egress label edge router (LER) is the network device, and acquire an adjacency index of an adjacency entry in an adjacency table according to the destination IP address of the inner IP datagram from the L3VPN packet. The network device may acquire a PW extended index of a PW extended entry in a PW extended table and a private network layer-2 header for the inner IP datagram from an adjacency entry having the adjacency index. By using the private network layer-2 header and a public network label, a private network label and a public network layer-2 header in a PW extended entry having the PW extended index, the network device may encapsulate the inner IP datagram into a L2VPN packet and forward the L2VPN packet through a physical egress interface in the PW extended entry.Type: GrantFiled: January 29, 2016Date of Patent: December 10, 2019Assignee: Hewlett Packard Enterprise Development LPInventor: Dan Meng

Patent number: 9692716Abstract: When needing to forward a packet from a switch line card to a programmable line card, the switch line card may encapsulate a pseudo-Layer 2 header for the packet based on uplink forwarding process of the switch line card. The pseudo-Layer 2 header may carry an adjacency table index and an egress interface table index which is used by the programmable line card. Correspondingly, the programmable line card may obtain the adjacency table index and the egress interface table index from the pseudo-Layer 2 header of the packet, and then may re-encapsulate a real Layer 2 header for the packet based on downlink forwarding process of the programmable line card, and transmit the packet through a corresponding egress interface.Type: GrantFiled: April 23, 2014Date of Patent: June 27, 2017Assignee: Hewlett Packard Enterprise Development LPInventors: Dan Meng, Yunfeng Zhao
