Keep Echelon from listening. (Digest).In light of recently released information recognising the existence of the international `Echelon' signal intelligence (sigint) network, Albrecht Telecommunications developed its SEU-8200 ciphering module for highly secure communication over analogue (electronics) analogue - (US: "analog") A description of a continuously variable signal or a circuit or device designed to handle such signals. The opposite is "discrete" or "digital". radio channels. The system is based on complex digital signal processing See DSP. Digital Signal Processing - (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled). techniques and provides a speech encryption algorithm A formula used to turn ordinary data, or "plaintext," into a secret code known as "ciphertext." Each algorithm uses a string of bits known as a "key" to perform the calculations. The larger the key (the more bits), the greater the number of potential patterns can be created, thus making that avoids the disadvantages of existing Vocoder-based units. The SEU-8200 is neither susceptible to attack by eavesdroppers nor decipherable de·ci·pher tr.v. de·ci·phered, de·ci·pher·ing, de·ci·phers 1. To read or interpret (ambiguous, obscure, or illegible matter). See Synonyms at solve. 2. To convert from a code or cipher to plain text; decode. by using current analytical methods. The ciphering system can be integrated into existing radio networks without the need to change either communication structures or hardware. A ruggedised military version is available. |
