At the same time the method of encoding clear text message, the computer program, and the device (the simplicity efficient one pass certification encoding system)

摘要

Topic This invention the security level which is identical with existing single pass certification encoding system is offered as, offers, more efficient encoding system and the device. Solutions At the same time as for the initialization vector which is the essential part of these systems, incremental it is selected in a safe way. Because of this, also the incremental method of forming the mutual finite difference even sequence or the XOR universal sequence which is another essential part of this system is offered. Incremental characteristic of these sequence formations to be applied when the clear text message which is encoded differs even, therefore it is bound up with the conservation of substantial encoding time. The conservation characteristic where as for further encoding step being redundant is shown, is higher than former system is brought. With another execution form dividing clear text block into two gathering is stated. Block code is used with encoding mode vis-a-vis gathering of one side, block code is used with decoding mode vis-a-vis gathering of another side, the result beneficial hardware solution is offered.
