Abstract: An automated mechanism is provided for generating and distributing appropriate certificates for end entities in a distributed public key infrastructure environment based on trust relationships between the endpoints. Policies between trust zones are specified as an arbitrary graph, referred to as a trust graph. A password is assigned to a trust zone or an individual endpoint by the Certificate Authority. When an endpoint requests a certificate using the appropriate password, the certificate authority uses this graph to generate the appropriate certificates for the endpoint. The distribution of certificates is automated using the Certificate Management Protocol.

Abstract: A processing system (206) defines (302) a plurality of bins (230) within a sliding time window, each bin for storing a total transmit duration of a predetermined number of frames assigned to each bin. The processing system then determines (310) a mean transmit duration per frame for a next one of the plurality of bins to be processed. The processing system subtracts (312) the mean transmit duration per frame from the total transmit duration of the one of the plurality of bins, when a next frame begins to be processed; and calculates (314) a transmit duty cycle for the sliding time window, the transmit duty cycle calculated as if a requested transmit duration for the next frame were to be allowed. The processing system also delays (316) a transmission of the next frame, when the transmit duty cycle is greater than a maximum allowable transmit duty cycle.

Abstract: A processor (206) and a receiver (202) monitor (301) a channel. The processor determines (304, 306) an average received signal quality on the channel and a first derivative of the average received signal quality. The processor then adjusts (308-336) the rate of background scanning to a value determined from an absolute value of the first derivative when the first derivative is positive and the average received signal quality is less than an acquisition threshold, and when the first derivative is negative and the average received signal quality is greater than the acquisition threshold.
