United States Patent 115
Abstract
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 infor- mation 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.

Technology Domain:
Unidirectional Wireless Access Systems
Product Category:
Garage Door Openers & Keyless Entry Fobs
Plain-English Summary:
Electronic lock systems where data flows in only one direction—typically from the key or remote transmitter to the lock receiver.
Relation to Claims:
The abstract specifies an encoder transmitting an encoded value to a decoder using a non-linear algorithm, which describes a unidirectional data transmission scheme common in simple remote controls.
