A tap-proof phone home. (Digest).A new tap-proof crypto-secure telephone is in the making for the German Armed Forces. Rohde & Schwarz recently captured a five million Euro award to develop a military version of its Elcrodat 6-2 (shown), aptly named the Elcrodat 5-4, for use in analogue and ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. telephone networks. The phone uses standardised Adj. 1. standardised - brought into conformity with a standard; "standardized education" standardized standard - conforming to or constituting a standard of measurement or value; or of the usual or regularized or accepted kind; "windows of standard width"; Nato encryption algorithms 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 to ensure end-to-end tap-proof transmission of voice and data. Key distribution is performed automatically via the crypto See cryptography. material distribution centres already in operation throughout the German Armed Forces. The Elcrodat 5-4 is primarily being designed for office use, but satellite connections can be established from mobile applications in the field. |
