摘要： A method and system for the remote control of devices having a secure self learn capability. The system includes an encoder and a decoder, the encoder encoding variable information including a user key using a non-linear algorithm to produce an encoded value transmitted to the decoder, the decoder decoding the value using the same algorithm. In a learning mode a new encoder is to be added to the system. The new encoder produces an encoded value using a key generation seed. The decoder, upon receiving the encoded key generation seed, produces a decoding key based upon the decoded key generation seed. The decoding key is stored in the decoder memory allowing valid recognition of the new encoder in a secure manner.

摘要： Encoder and decoder microchips suitable for use in secure unidirectional remote control devices. The encoder microchip includes circuits for performing and encoding function on an identification number embedded in the microchip and a combination of a characterization number and a stepping counter value, so as to generate a transmission value which is only decidable by a related decoding function having access to the same identification number. The decoder microchip includes circuits for decoding the transmission value into a decoded characterization number and a decoded counter value and circuits for comparing the decoded counter value with a decoded counter value range. The encoder and decoder microchips are also provided with means for synchronizing the decoder microchip with a particular encoder microchip which has generated a synchronization command.
