Patent ES-341955-A1 (ES)
Title: Enciphering teleprinter text for telex channels
IPC: H04L9/36
Filed: 1967-06-17
Abstract: A cipher pulse generator includes feed-back shift registers in which each feed-back signal is obtained by combining the outputs of a number of stages of the register. The registers' outputs feed a modulo-2 adder which provides the cipher signal. In the system described teleprinter signals are ciphered. The cipher generators at both transmitter and receiver comprises two feedback registers, REG. I and REG. II, the feedback signals being selected by plugboards. The cipher signal is stored in a register REG. Z. Each clear character from the teleprinter is read in to a first shift register, REG. X, which includes a feed-back loop and modulo-2 adders. A number P of shift pulses is now applied to REG. X, determined by a counter which is counted down to zero from P by clock pulses, P being derived by modulo-2 addition of the outputs of selected stages of REG. I and REG. II. The content of REG. X when shifting is ended is a first -ciphered signal which is modulo-2 added to the cipher signal from REG. Z and the resulting second-ciphered signal is returned to REG. X from which it is read out to a store prior to transmission. At the receiver the inverse process takes place, the receiver register REG. X being stepped backward by P steps to provide the deciphered signal. To ensure that registers REG. I and REG. II at the transmitter and receiver start from the same position a synchronizing sequence of six characters precedes the clear characters. If the cipher signals are used in a telex system signals such as " All Space " or " Figure Shift D " would cause undesired operations. It is therefore arranged that any " Figure Shift," or " All Space " signal cannot appear in the transmitted text. The clear text signal stored in REG. X (which is never All Space because this is not used) is inspected prior to stepping the register. If the signal is Figure Shift it is replaced by Carriage Return, and if it is Carriage Return it is replaced by Line Feed. The signal now stored undergoes the first and second ciphering processes and the result is inspected. If it is either All Space or Figure Shift the second ciphering is repeated so that the signal is replaced by the original firstciphered signal. At the receiver the signal undergoes a second-deciphering process corresponding to the second ciphering. If the result is All Space or Figure Shift the signal is seconddeciphered again. The second-deciphered signal is now first-deciphered and the result checked. It it is Carriage Return it is replaced by Figure Shift. If it is Line Feed and is followed by another Line Feed one of these is replaced by Carriage Return. The above description also applied if Line Feed is read for Carriage Return and vice versa. Reference has been directed by the Comptroller to Specification 1,120,032.
