摘要： The process is intended to establish whether the data transmitted by the transmitter (SE) to the receiver (EM) have been tapped and spuriously reintroduced at a later point in time and/or have been inadmissibly altered. For this purpose, the signature (S) assigned to the useful data (D) is enciphered symmetrically, using a combination of coupling data (K), characterizing the coupling between transmitter and receiver, and random data (Z), generated by a random generator. The coupling data are transmitted in plain text, the random data are enciphered. On the receiver side it can be established whether the transmitted message has been tapped and reintroduced at a later point in time if the coupling data are inadmissible. An alteration of the transmitted message can be established from ascertaining that the key used for enciphering the signature, obtained from the combination of coupling data and random data with the aid of a one-way function, does not correspond to the key obtained during deciphering at the receiver and consequently the deciphering of the enciphered signature leads to an incorrect result. The incorrect signature is detected during verification of the signature.

摘要： Food pieces, such as cubed apples, the exposed pulp of which tends to discolor upon exposure to air, are treated with an acidic aqueous solution which is effective in maintaining the natural color of the exposed pulp and which comprises citric acid, calcium chloride, and sodium chloride, with the treatment of such apples being preferably practiced by means of novel apparatus which uses a screw conveyor which receives the pieces of food at its inlet end and moves them from its inlet end to its outlet end automatically while the treating solution is continuously injected into the conveyor to coat the food pieces. Injection of the treating solution is controlled in response to control signals derived from a gamma ray weigh scale which weighs the food pieces continuously as they pass through the conveyor, so that the amount of treating solution injected is maintained in predetermined proportion to the rate at which the food pieces pass through the conveyor.
