Digital radio signal encryption/decryption

The invention encompasses a digital radio transmitter (2), a digital radio receiver (2) and a method of randomising data for digital radio transmission. A first digital signal (S1) contains voice and/or data. A second digital signal (S2) comprises different short pseudo-random data sequences, the second digital signal (S2) changing between different short pseudo-random data sequences at pre-defined time points. Both the order of the short pseudo-random data sequences and the timing of the pre-defined time points may vary in a pseudo-random manner. The first (S1) and second (S2) digital signals are combined to produce a third digital signal (S3) for transmission. Synchronisation data (320-332) is added to the signal, identifying the pseudo-random sequence currently in use. A digital radio receiver (2) is adapted to generate the second digital signal (S2), and to use this to extract the first digital signal (S1) from the received radio signal.

Signal transmission system having encoder/decoder without frame synchronization signal

A privacy code-type signal transmission system includes a transmitter having a signal sampler for producing analog samples of an analog audio signal, an analog to digital converter, a scrambler, a multi-level analog former and modulator means. The analog to digital converter converts each analog sample into a parallel n bit digital signal. The parallel n bit digital signal is scrambled by a digital scrambler to produce a second parallel n bit digital signal. The second n bit digital signal is input to a multi-level former having 2n different levels, the output of which is a 2n level analog signal which is suitably modulated for transmission to a receiver. The receiver demodulates the 2n level analog signal and with a level discriminator converts the demodulated signal to a scrambled digital signal corresponding to the scrambled digital signal produced at the transmitter. The original analog audio signal is then recovered by descrambling the digital signal and applying the descrambled digital ...

System and method to prevent misuse of aircraft messages

Aircraft signal transmission comprising transmitted data has false information introduced into it so that the transmitted data includes true and false aircraft position and movement information. Thus an avionics system may include an automatic dependent surveillance-broadcast (ADS-B) transponder 20 to generate ADS-B Out messages 21 and an airborne ATC processor 25 which causes the transponder to transmit authorised bogus ADS-B Out messages 24 which are recognized as false only by authorized users 22. The bogus flight trajectory may be generated so as not to conflict with trajectories of neighbouring aircraft. The airborne processor may also detect maliciously spoofed ADS-B Out messages 28. Thus misuse of ADS-B Out information for malicious cyber or physical attack is prevented.

The speech sections are read-in to registers 0-7 or a direct link D according to the number sequence whilst the numbers of the one preceding and two succeeding registers, in this case 1 and 3, 4 are stored in register K, representing prohibited sections. Each new register address is compared in V with those in K and if match exists unity is added to the addressed number and comparison repeated until no match occurs, whereupon that number opens switches W1, W2 to the corresponding register. Detector BC inserts the direct link D to prevent loss, and repetition may be effected if the level of a section is too low. Reference has been directed by the Comptroller to Specification 1,353,693.

FUNKTELEFONIESYSTEM

Apparatus for the scrambled transmission of analogue signals

A scrambling circuit VS in the subscriber terminal TEG of a mobile telephone system is connected to the signal path via an analogue/digital converter A/D. The signal to be scrambled is digitized and forwarded to a digital signal processor DSP. The latter contains a predistorter VV for high-frequency raising, which alters the characteristic energy distribution of human speech. Four frequency bands are exchanged according to a code in a frequency band interchanger FBT. The said code is generated by a code generator CG and transmitted via a pilot tone transmitter PS in the audio frequency band. This means that the switching-related signalling is not influenced. An equalizer EZ lowers the high frequencies again. In a base station BS, the code is made available by a pilot tone receiver PE for descrambling. Signals from the base station BS to the subscriber terminal TEG are encrypted using the same code. Although the subscriber terminals TEG generate the code, they do not decrypt it. The base ...

PROCEDURE AS WELL AS MECHANISM FOR THE BROADCASTING OF INFORMATION

Method for scrambling voice signals

A frequency band interchange method is employed for scrambling voice signals during radio transmission. The higher frequencies of the energy spectrum are raised prior to transmission. 40% of the energy of human speech is in the range of 400-800 Hz. If the frequency bands 1, 2 lying in this range are exchanged with respect to higher frequencies, overdriving results in the case of the subsequent high-frequency raising. Furthermore, analysis of the frequency bands having the greatest amplitude enables the signal to be descrambled with high residual comprehensibility. Therefore, the higher frequencies of the voice signal are raised prior to scrambling in such a way that a virtually linear energy distribution is produced. After the interchange and inversion of the frequency bands 1, 2, 3, 4, the high frequencies are lowered again and a spectrum is produced which is approximated to the clear voice signal. ...
