Abstract: Various embodiments set forth techniques for efficient transmission of compressed certificates. The techniques include receiving, at a first node from a second node, a first certificate compression dictionary that includes one or more first mappings; processing, by the first node, the one or more first mappings to identify one or more first certificates that are known to the second node; identifying, by the first node, a second certificate not included in the one or more first certificates; and transmitting, by the first node to the second node, the second certificate.

Abstract: Techniques for messaging based on trust levels and resource limitations in a mesh network include receiving, by a first node of a mesh network, a message; determining, by the first node, a security key type based on a resource parameter associated with a neighbor node included in the mesh network; securing, by the first node, the message using a security key of the security key type; and transmitting, by the first node, the secured message to the neighbor node. The resource parameter associated with the neighbor node comprises at least one of an amount of memory used to decrypt the secured message at the neighbor node, an amount of power used to decrypt the secured message at the neighbor node, or an indication of an amount of power remaining at the neighbor node.

Abstract: Various embodiments set forth a method comprising receiving, at a server node from a client node, a client compression dictionary that includes one or more first mappings between one or more first index values and one or more data entries included in a certificate cache of the client node; identifying, in response to receiving the client compression dictionary and based on the client compression dictionary, one or more certificates that should be transmitted to the client node; and transmitting, from the server node to the client node, the one or more identified certificates.

Abstract: A network node can be configured to provide a network function virtualization orchestrator (“NFVO”) in a virtualization environment. The network node can determine that information associated with an unrecognized resource meets criteria associated with a reference definition for a type of recognized resource. The network node can, responsive to determining that the information associated with the unrecognized resource meets the criteria, store an indication of the unrecognized resource as a recognized resource.

Abstract: A method of securely providing a trusted time to a first device may include receiving at a network interface controller (NIC) a neighbor list comprising a plurality of entries for a corresponding plurality of neighbor devices wherein each of the plurality of entries includes a unique device identity of a time server which the plurality of neighbor devices has reached, and an inception time of a time server certificate corresponding to the unique device identity. The method may further include sorting the plurality of entries within the neighbor list to obtain a sorted neighbor list and sending a time request to a first neighbor device of the plurality of neighbor devices based at least in part on the sorted neighbor list.

Abstract: Various embodiments disclose a method including detecting, by a first node in a mesh network while the first node is operating in a normal power mode, an outage event; in response to detecting the outage event, switching to operating the first node and a first memory of the first node in a low power mode, wherein the first memory is capable of switching between operating in the normal power mode and in the low power mode where an amount of power used by the first memory is reduced; and while operating the first node and the first memory in the low power mode: generating, by the first node, a first message; securing, by the first node using a key retrieved from the first memory, the first message; and sending, by the first node, the first message to a second node in the mesh network.

Abstract: Various embodiments disclose a computer-implemented method for sending a message associated with an outage event, comprising, at a first node in a network, receiving a key from a second node in the network, wherein the second node is adjacent to the first node; storing the key in a first memory, wherein the first memory is capable of operating in a low power mode; detecting an outage event; in response to detecting the outage event, operating a first processor in the low power mode; and via the first processor operating in the low power mode: generating a message, securing the message using the key, and sending the message to the second node.

Abstract: Techniques for messaging based on trust levels and resource limitations in a mesh network include receiving, by a first node of a mesh network, a message; determining, by the first node, a security key type based on a resource parameter associated with a neighbor node included in the mesh network; securing, by the first node, the message using a security key of the security key type; and transmitting, by the first node, the secured message to the neighbor node. The resource parameter associated with the neighbor node comprises at least one of an amount of memory used to decrypt the secured message at the neighbor node, an amount of power used to decrypt the secured message at the neighbor node, or an indication of an amount of power remaining at the neighbor node.

Abstract: A computer-implemented method of transmitting messages within a mesh network comprises: receiving at a first node included within the mesh network a network message that is to be broadcast within the mesh network; determining a security key type based on at least one of a resource parameter associated with at least one neighbor node included in the mesh network or an attribute of the network message; securing the network message with a security key of the security key type to generate n secured network message; and broadcasting the secured network message to one or more other nodes included in the mesh network that are directly connected to the first node.

Abstract: Various embodiments set forth a method comprising receiving, at a server node from a client node, a client compression dictionary that includes one or more first mappings between one or more first index values and one or more data entries included in a certificate cache of the client node; identifying, in response to receiving the client compression dictionary and based on the client compression dictionary, one or more certificates that should be transmitted to the client node; and transmitting, from the server node to the client node, the one or more identified certificates.

Abstract: An anti theft tag with separated encapsulated RFID tag and an EAS label, wherein the tag comprises a first plastic body equipped with an EAS label, a second plastic body in which a pin engagable to an EAS label is accommodated, said pin is releasably lockable to a locking mechanism of the EAS label, the pin has a head and a stem formed so that it may be engaged with the locking mechanism of the EAS label, and further, the second plastic body contains an RFID inlay. Said plastic body can be injection moulded onto said RFID tag. The operating frequency band of the RFID tag is adjusted by the material of the plastic body and the thickness of the material encapsulating said RFID tag. The material of the plastic body preferably comprises a filling material having a relative dielectric constant exceeding that of the base material. The RFID tag can be inserted into a cavity of said plastic body composed of two parts defining said cavity.

Abstract: A device for removing a damaged locking cylinder, which eliminates the need for removing the escutcheon plates, which employs an internal locking bolt acting in concert with locking arms mounted on a locking plate, to selectively tighten or loosen the locking cylinder, as required, by use of an external adjusting mechanism which mates and co-acts with the locking bolt. Also provided is a cylinder protector which is affixed over the locking cylinder to deter vandalism of the cylinder by use of a tool.
