  • Publication number: 20240419795
    Abstract: Example dynamic code segment measurement methods, apparatuses, and devices are provided. In one example, a code segment in at least one of a memory of a user-mode process or a kernel is measured to obtain first measurement data. A determination is made as to whether the first measurement data is consistent with target baseline data. When the first measurement data is consistent with the target baseline data, hash calculation is performed on a memory area occupied by the target baseline data to obtain a first digest value. If the first digest value is capable of completing unseal, it is determined that the code segment is not tampered with, and the target baseline data is not tampered with. If the first digest value is not capable of completing unseal, it is determined that the target baseline data is tampered with.

  • Patent number: 9350711
    Abstract: A data transmission method is applied in a virtual private network (VPN) and includes: querying, by an initiating client, a VPN server for external network Internet Protocol (IP) addresses of the initiating client and a responding client; performing, by the initiating client, key negotiation with the responding client through the VPN server; after the key negotiation is completed, writing, by the initiating client, the external network IP address of the initiating client into a source address field of a to-be-sent User Datagram Protocol (UDP) packet, writing the external network IP address of the responding client into a destination address field of the to-be-sent UDP packet, and encrypting the to-be-sent UDP packet according to a key obtained through the negotiation; and sending, by the initiating client, an encrypted UDP packet to the responding client, and performing packet interaction with the responding client directly.
