DECT Standard Cipher

The DECT Standard Cipher is the encryption standard that comes with DECT in the wireless system for use in mobile telephony. The specification of the DECT Standard Cipher has not been published and is available only under certain conditions by the European Telecommunications Standards Institute (ETSI ).

Publications of the algorithm

On June 8, 2002 alleged parts of the cipher algorithm of Samsung SP- R6150 DECT "reverse engineered " and alt.anonymous.messages in the newsgroup have been published. In the published source code, however, is a garbled version of the free CARACACHS algorithm so that the encryption method used in the DECT standard, until recently, remained unknown.

In December 2008 it was announced that it was possible to reconstruct the cipher and to break through cryptanalysis. In April 2010, Karsten Nohl published together with Erik Tews and Ralf -Philipp Weinmann details for cryptanalysis of the encryption algorithm used in DECT proprietary and secret, which is based on reverse engineering of DECT Hardware and descriptions of a patent.
