The present invention discloses an apparatus and method for delivering a revocation list over a one-way broadcast network to receivers with limited memory capabilities. In one example, the revocation list is partitioned to form a first certificate revocation list (CRL) sequence if the number of entries in the revocation list exceeds a predetermined value. Individual identification numbers belonging to a first identification number series are subsequently assigned to partitions of the first CRL sequence. Afterwards, the first CRL sequence is interleaved into a first content transport stream.

A mapping program includes an overlay grid of intersecting lines represented by two series of numbers. An origin is defined and an area of interest is defined. The origin corresponds to a location on a map. One series of numbers relates to longitude; while the other series of numbers relates to latitude. Each series of numbers are represented by two or more digits. Each digit represents up to 35 different numerals or letters. When two digits are used to represent a location, the combined number of lines for each series of number may comprise up to 1225 lines. Thus, the total number of lines represented by each series of number corresponds to a power of the base number of possibilities up to 35; the power being represented by the number of digits used in each series of numbers. These numbers are overlaid onto a map having points corresponding to actual longitudinal and latitudinal locations. A device for converting between the latitude and longitude is provided. A storage medium is also provided for storing a series of steps to perform the operations.

The invention relates to a communication method of a distributed scheduling system based on a local area network multicast group. Since the IP addresses in the same network segment must be different in the method, the random number sequences must be incongruent, and an arbitration result must be obtained. Since multiple robots use exactly the same algorithm, the results of their respective arbitration pairs are also exactly the same. Accordingly, after a conflict occurs, the arbitration can be completed without any communication between the conflicting robots. That is, arbitration does not consume any bandwidth at all, except for the necessary information such as robot position, direction, and resource application that need to be transmitted during scheduling. Logging in and out also only results in very small data transfers at boot time. This method enables multiple robots moving indoors to share scheduling information with the minimum network bandwidth, and supports adding new robots at any time without any configuration.

The objective of the invention is to provide an encoding method and a communication method wherein bit-error correction is easy for a authorized recipient but difficult for an unauthorized recipient. A transmission channel in which bit errors are moderately controlled is used to transmit / receive a random number sequence.

The unit of the encoding is equal to or greater than the length of the common key so as to make a partial analysis by an unauthorized recipient impossible.

The invention relates to an anti-attack anti-theft system. Systems and methods for anti-theft of vehicles are provided. Each of the two or more locking point devices generates a random number and broadcasts it to all other locking point devices. Each of the lockpoint devices retains its own local copy of the nonce and concatenates its own local copy of the nonce to the other of the two or more lockpoint devices from the bus A random number for the device. From the nonce broadcast on the bus all nonces are concatenated in a predetermined sequence to form a single challenge, which is sent to the remote transponder. Each locking point device then compares the individual response from the transponder with its local concatenation. When a specific portion of the response from the transponder matches the local series, the function of the locking point device is enabled.
