  • Patent number: 11128456
    Abstract: In one example, a network entity obtains a network packet including data. The network entity performs a deterministic mathematical computation on the data to produce a string of characters derived from the data and inserts an indication of the string of characters into the network packet. The network entity provides the indication of the string of characters to a distributed ledger based on a secret unique identifier of the network entity. The distributed ledger stores the indication of the string of characters and records an indication of a time at which the indication of the string of characters was stored in the distributed ledger. The network entity obtains, from the distributed ledger, the indication of the time and inserts the indication of the time into the network packet. The network entity provides the network packet towards a destination.

  • Patent number: 11108814
    Abstract: A web conferencing operator can enable participants to share multimedia content in real-time despite one or more of the participants operating from behind a middlebox via network address translation (NAT) traversal protocols and tools, such as STUN, TURN, and/or ICE. In NAT traversal, participants share a transport addresses that the participants can use to establish a joint media session. However, connectivity checks during NAT traversal can expose a media distribution device hosted by the web conferencing operator to various vulnerabilities, such as distributed denial of service (DDoS) attacks. The web conferencing operator can minimize the effects of a DDoS attack during the connectivity checks at scale and without significant performance degradation by configuring the middlebox to validate incoming requests for the connectivity checks without persistent signaling between the web conference operator and the middlebox.
