Chaotic associative memory and private v-mails

To support the 3rd generation cellular phone with broad band wireless video emails (Vmails), we develope a chaotic neural network (CNN) associative memory whose tying and initial value were sent by a private and free version of RSA security algorithm (patent expired). Receiver devices with the embedded system chip regenerate the specific CNN image series, so called the spatial-temporal keys (STK), which allow the RSA and the V-mail data to be correctly decrypted. Due to the fading and fatal noise in wireless communication channel, the STK must be robust and fault-tolerant proved by a field theory of associative memory and demonstrated by a collective fixed point of cycles of the whole bifurcated images.
