摘要： A method, implemented in a communication device, of indicating a service supported by the communication device. A hash value is generated, using a hash function, based on a service identifier associated with the service. Respective portions of the hash value are mapped to respective bit locations in a bit string that represents membership of the service in a set of services supported by the communication device. The bit string is generated at least by setting the bit locations in the bit string to values that indicate that the service is supported by the communication device.

摘要： In a method for efficient password based public key authentication between a first user device and a second user device, a shared password is received by a first user device which generates a first hash value of the shared password and a first value, wherein the first value is composed of at least a product of the first hash value and a first unique security constant associated with the first user. The first user device then generates a first random value generated using data from a generator element, and a first blind public key associated with the first user device, wherein the first blind public key is generated using a first public key. The first user device concurrently sends the first value and the first blind public key to the second user device for authentication.

摘要： The present disclosure describes methods and apparatus for selecting a device to perform shared functionality in a deterministic and fair manner in a wireless data communication system. A wireless data communication system includes multiple wireless transceiver devices and certain functionality, such as the transmitting of a beacon used to synchronize the wireless transceiver devices, is distributed among the wireless transceiver devices. Each wireless transceiver device generates a device rank for a given time for itself as well as one or more other wireless transceiver devices in a deterministic and fair manner. Each wireless transceiver device determines the same device ranks for the wireless transceiver devices, and each wireless transceiver device selects the wireless transceiver device having a highest device rank at any given time as the wireless transceiver device that is to perform the functionality at that given time.

According to one embodiment, an apparatus includes a non-volatile memory. The apparatus includes key logic configured to expand a seed value to form a key. The seed value is a sequence of random bits. The apparatus includes inspection logic configured to inspect the key to determine whether the key is valid for use as a cryptographic key. The key logic is configured to store the seed value in the non-volatile memory if the key is valid, and if the key is not valid, the key logic is configured to modify the seed value to form a modified seed value, to generate a new key from the modified seed value, and to repeat inspecting the new key and modifying the seed value until a valid key is determined.
