A method for which is safe for signaling purposes transmit data between the computers which is safe for signaling purposes as well as apparatus for this purpose

摘要

The method according to the invention provides that the arranging appendix (p, p * *) for the in a computer (srq, srs) user data (n) is formed, for the most part, outside of the computer which is safe for signaling purposes in a commercial computers (kq, ks) to calculate. Only a final calculation over all in the commercial computer calculation steps, which is carried out in the computer. For this purpose, the corresponding data (n, p *) between the computer and the am certain computer exchanged. At the receiver end, in a likewise commercial computers (ks) according to the same laws as at the transmitting end of the transmitted useful data (n) of the incomplete test data (p *) is calculated and transmitted to a receiver-side reliable computer. This, the still missing for the calculation steps in the not reliable computer (srs) incomplete formed test data (p *) and compares the calculated in this test data (p * *) of the transmitting end, with the transmitted test data (p), in the event both test data, the transmitted useful data recognized. Due to the greatest possible degree of aging of the calculation for the test data, the data transmission as a whole, more rapid, particularly because, for the calculation of the test data can be used any desired rapid computer. The securing of the data transmission, by means of which both on the transmitter - as well as on the receive side in a ..
