| Description: | Accepted in Physics Letters A, (June 2008)
http://dx.doi.org/10.1016/j.physleta.2008.06.066 This Letter describes how to determine the parameter of the chaotic Lorenz system used in a two-channel cryptosystem. First the geometrical properties of the Lorenz system are used to reduce the parameter search space. Second the parameters are exactly determined - directly from the ciphertext - through the minimization of the average jamming noise power created by the encryption process. The work described here was supported by Ministerio de Ciencia e Innovación of Spain, research grant TSI2007-62657 and by CDTI in collaboration with Telefonica I+D, project SEGUR@ (CENIT 2007-2010).
