摘要： A symmetric-key cryptographic technique capable of realizing both high-speed cryptographic processing having a high degree of parallelism, and alteration detection. The invention includes dividing plaintext composed of redundancy data and a message to generate plaintext blocks each having a predetermined length; generating a random number sequence based on a secret key, generating a random number block corresponding to one of the plaintext blocks from the random number sequence, outputting a feedback value obtained as a result of operation on the one plaintext block and the random number block, the feedback value being fed back for using the operation on another plaintext block, and performing an encryption operation using the one plaintext block, random number block, and feedback value.

摘要： 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.

摘要： 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.
