Abstract: A message that contains train on-track information and reservation information of a train detection section and direction information and reservation information of a switch is circulated among a train detector, switch machine, signal device controller and a route indicating device. Via a signaling message, the train detector transmits the train detection result to the signal device controller and the route indicating device, the switch machine can transmit switch condition to the signal device controller, the route indicating device transmits route reservation to the switch machine and the signal device controller. Based on the transmitted train detection result, switch condition and route reservation condition, the signal device controller transmits travel permission or travel non-permission for the assigned route to a train.

Abstract: To achieve high safety, large-sized nonlinear permutation is employed; however, the larger permutation processing is, the more the period of time required for the processing is, which hence is not efficient. There is provided a hash value generation method or a hash value generator which has the following aspects and which is highly safe and is capable of executing processing at a high speed. 1. As a message insertion method, there is employed a linear conversion in which the insertion message affects all subblocks. 2. An internal state is divided into a plurality of subblocks, and nonlinear permutation is conducted in each subblock unit. 3. Additionally, the linear conversion of item 1 above may be configured such that each subblock of the internal state affects the subblocks of the output.

Abstract: Trains and points are patrolled by a telegram containing the block occupancy information as a section that only one train is permitted to occupy, the information for giving lock position instructions to a point, and the point position information. This telegram is updated in order to get the right of block occupancy that is not held by other trains, and to give lock position instruction to the point. The train checks the block which this train is allowed to occupy, confirms that the point in this block has been set to the lock position specified by this train. Reading the aforementioned telegram, the point checks the lock position instruction given to itself and controls its lock position. A signaling system characterized by reduced designing and manufacturing costs is provided.

Abstract: A hash value generation device has a control part (120) that divides an inputted message into N message blocks of a predetermined data length (N being a natural number), repeats transformation processing a predetermined number R of rounds (R being a natural number larger than or equal to 2) for each of the message blocks, and repeats, N times, block cipher processing in which a value calculated in the transformation processing of R rounds for the n-th message block (n being a natural number) is used as key information for the (n+1)-th message block, to generate a hash value of the inputted message. In shift processing performed in the transformation processing of the control part (120), at least one odd number and at least one even number are included among numbers of bits by which a shift is performed.
