    摘要: Systems and methods of conducting collaborative sessions between mobile devices may provide for determining a time delay associated with a set of participating mobile devices, and determining a command execution time based at least in part on a clock of a managing device and the time delay. One or more control messages may be transmitted to the participating mobile devices, wherein the control messages include the command and the command execution time. Upon receiving a control message, each participating mobile device may determine a local execution time based at least in part on the command execution time and an offset of the clock of the managing device relative to a local clock. Execution of the command can therefore be coordinated across the set of participating mobile devices.

    摘要: Embodiments provide techniques for device power management in wireless networks. For instance, an apparatus may include a power management module, and a transceiver module. The power management module determines a beacon interval and a wakeup interval. The transceiver module to send a transmission to one or more remote devices that includes the beacon interval and the wakeup interval. The beacon interval indicates a time interval between consecutive beacon transmissions of the apparatus, and the wakeup interval indicates a time interval between when the apparatus receives two consecutive beacons from a peer device.

    摘要: Techniques to overlay ciphersuite negotiation on top of the mesh link establishment protocol without sacrificing security. Two cryptographic primitives may be utilized: (1) a message integrity code, which is denoted as mK, where K is an authentication key (mK may be utilized to detect forged messages); and (2) a cryptographic random number generator, which will be denoted as rng. The techniques may use rng to produce values that cannot be predicted by any polynomial time algorithm.

    摘要: An embodiment may include circuitry to at least one of generate at least in part, receive at least in part, and request at least in part, a token. The token may identify, at least in part, a device to an entity. The token, as received by the entity, may be encrypted, at least in part, based at least in part upon the entity's public key. The token may be generated by an authorized provider of the token based at least in part upon an identifier of the device and a signature. The signature may be generated based at least in part upon the provider's private key and the identifier. The token, as received by the entity, may be capable of being decrypted at least in part, based at least in part upon the entity's private key. The entity's private key may be maintained in secrecy from the device and provider.

    摘要: Key derivation procedures and key hierarchies compatible with the mesh link establishment protocol for use in a mesh network. A single cryptographic primitive may be utilized, which is a key derivation function, denoted as kdfK, where K is a cached pairwise master key. The result of the function kdfK may be used to derive the keys used to secure both link establishment and the data subsequently exchanged over the link.
