  • Patent number: 12212663
    Abstract: Embodiments for bounded broadcast encryption key management in a peer-to-peer network are described. To realize bounded broadcast encryption key management, a second peer of the peer-to-peer network receives a first broadcast message from a first peer. The first broadcast message includes at least a public key associated with the first peer. The second peer then generates a key seed in response to receiving the first broadcast message, and creates a second message that includes the key seed encapsulated with the public key. The second peer then transmits the second message to the first peer, and in response to the transmission of the second message, receives a packet from the first peer. The packet includes data encrypted using a secret key derivable from the key seed and one or more portions of the second message.

  • Patent number: 11750581
    Abstract: Embodiments of a secure communication network are disclosed. For secure communication of data packets, a method implemented in a core node, is presented. The method includes receiving a double encapsulated data packet associated with a first layer and a second layer of encapsulation/encryption. The method further includes decapsulating/decrypting a second layer of encapsulation/encryption to access a portion of the data packet and re-encapsulating/re-encrypting at least the accessed portion with another second layer of encapsulation/encryption. The method further includes transmitting the re-encapsulated/re-encrypted data packet to a subsequent node based on the accessed portion.

  • Patent number: 10709913
    Abstract: The present system for fall restraint includes a mounting frame connected to a trigger mechanism and firing blocks, with a trigger cable extending through apertures in the mounting frame and trigger mechanism. Sudden movement by a user, such as a fall, actuates the trigger mechanism to trigger the firing blocks. The firing blocks are loaded with anchors and firing cartridges. Triggering the firing blocks causes the cartridges to fire, propelling the anchors into an anchoring surface, such as a roof. Because the user is connected to the trigger cable, once the anchors deploy the user is anchored to the roof and their fall arrested.

  • Patent number: 7088737
    Abstract: A method and apparatus for combining data packets having different protocol encapsulations within a circuit is described. In one embodiment, a method includes receiving a number of Internet Protocol (IP) packets over Ethernet on a real circuit. Each IP packet over Ethernet has an Ethernet header and an IP address. The method also includes removing the Ethernet header from the number of IP packets. Moreover, a number IP packets within a Point-to-Point Protocol (PPP) over Ethernet are received on at least one virtual circuit. Each of the number of IP packets within the PPP over Ethernet includes a PPP header, a PPP over Ethernet (PPPoE) header, an Ethernet header and an IP address. Additionally, the at least one virtual circuit runs within the real circuit. The method also includes removing the PPP header and the PPPoE header from the number of IP packets within the PPP over Ethernet and removing the Ethernet header from the number of IP packets within the PPP over Ethernet.
